after spending many years in research and development, cary audio brought out a line of digital home theater products to complement our music systems. sharing the same hallmark sound quality, whether used for surround sound or stereo music, these processors and amplifiers quickly garnered a reputation as the finest sounding home theater systems in the world. with the same fanatical insistence on achieving low noise and low distortion, selecting the best quality parts and the very latest in digital signal processing for both audio and video, sourced from the most respected suppliers, cary audio has succeeded in once again not only raising the bar, but setting a new standard for entertainment systems. taking digital design a step further, cary audio is now introducing a new generation of source components that allow streaming of music to and from a network, easy archiving and enjoying a large cd collection, and accessing the myriad of music available via internet radio .
our output tubes are new production tubes and are installed in matched sets. because they are new production we are able to have them matched for us by our suppliers. as a result they will be all one brand. with regard to the many nos tubes utilized by us, we are buying them in large quantities from various suppliers and doing the matching here at cary audio. we are very familiar with the characteristics that are most important for tube life and optimum performance. rest assured that we have 100% quality control (qc) on your new cary audio component. in addition, we have done 100% qc on the included tube set with your new cary audio component .
the cary cad - 805c has become a classic. first introduced in 1991 as the cary cad - 805, this single - ended triode (set) monoblock amplifier looked and sounded completely different from any other high - end tube amplifier available at the time .

reviewing affordable gear, i will from time to time examine so - called
trickle - down
designs from high - end designers who have made their mark in the upper - price echelons. more and more, such designers are taking what they' ve learned and applying it to less - expensive products in order to broaden their customer base. cary audio design, for example, of single - ended triode fame, has entered the ring with the slm - 100 pentode monoblocks .

note: some other tube amplifier designs will oscillate or go into overload if they are used without a speaker or resistive load attached to the speaker output terminals. cary audio tube amplifiers are inherently stable designs and may be operated without a load on the output terminals for adjusting bias or while in burn in .
cary audio was founded in 1989 with a firm commitment to producing the very highest quality two - channel vacuum tube equipment, and we continue to innovate and lead the industry in this market sector. our dedication to accurate and lifelike reproduction of music has led to many awards and rave reviews all over the world. our efforts are guided by the knowledge that we sell not just audio gear, but rather a means to enjoy music and video entertainment .
plug the bias cable into the bias connection jack on the chassis and connect the ma meter. start by setting the bias potentiometer screw all the way counter - clockwise on your cary audio vacuum tube amplifier. this setting should yield a zero ma meter reading if the all of the output tubes are functioning properly .
by our unswerving insistence on quality and performance, and by constantly listening to our consumers, cary audio stays at the leading edge of our fast - developing industry. as we have evolved from strictly two - channel purist music systems into cutting - edge digital home theater and streaming solutions, we have remained true to our dedication to produce the finest high performance products on the planet. whether you listen to a brand new digital to analog converter (dac), streamer, or a tube preamplifier and amplifier that were developed 20 years ago, you’ll experience the comfort of knowing that you have invested in cary audio, the very best !
the unique slim design allows the model sub to be displayed prominently on the floor, mounted on the wall via the included keyholes, or laid flat on the floor to arrange the best bass response for your system .
a set of hand - matched tubes is provided with your slp - 05, as well as a matched pair that simply power a built - in headphone amplifier. all of this technology simply means that you will be listening to music that is lifelike in its richness and clarity, and full of the tiny details that raise the slp - 05 from simply good to world - class. cary audio’s attention to detail in circuit design, parts quality, and a superb finish, makes this truly an investment in musical enjoyment and pride of ownership .
the original cary cad - 805 was named after its output tube: the 805. the amp had a 6sl7 input tube (which has remained constant through various design changes) and an el34 driver tube. the 805 output tube was soon switched to a 211. dick olsher reviewed that version in january 1994 (vol. 17 no. 1), and it inspired john atkinson to write his most famous cover line with respect to the cary and a solid - state krell :
if either of these amplifiers is right... the other is wrong .

during production we assemble a new component, test it in the qc department with the tubes to be shipped with it, ‘burn it in’ on our burn in rack, test it again in the qc department and then pack it for shipment. all cary audio components have been burned in from 24 to as much as 72 hours prior to shipment and have been tested twice for performance against our rigorous test standards for each model. we do this so that you will have a great sound experience with our audio components .
cary audio’s finest preamplifier has been the recipient of many awards and glowing reviews. it consists of one enclosure housing the preamplifier itself, and a second separate power supply to keep noise out of the musical signal path and provide a more stable electrical foundation. like most cary audio products it is fully differential - balanced in construction to further reduce electronic noise, and uses no global feedback for faster response. the slp - 05 features three pairs of rca inputs plus a tape loop, as well as two pairs of xlr balanced inputs, and includes a cinema bypass mode so you can share sources between the music system and a home theater processor without worrying about degrading the signal path or having to readjust volume .
the model 10™ am / fm clock radio is the smallest and best performing stereo system we’ve produced in our 10 years of design and development. not since the introduction of the model one has a radio delivered such great reception and high fidelity sound .
my reaction to this experience was not to join in the single - ended triode frenzy, but to run in the opposite direction .
these cary guys are pretty clever. i wonder if they make any
balancing style technology and audio quality the model one digital is a radio for the modern era. it delivers a new spin on the original model one by offering dab / dab +, fm, wi - fi, and bluetooth®. it merges the simplistic elements and user - friendly features tivoli audio’s classic line is known for, but with a tech refresh .
i get a kick out of those who accuse cary of designing in or adding second - order harmonic distortion to a single - ended amplifier. we don' t add it; it comes right along with the design. now there' s a way of eliminating it. all one has to do is listen to a cary cad - 805c and turn up the feedback control. the amp becomes a real champ on the test bench with the feedback turned up. but what you find is that you' ve lost the richness, the foundation of the music, the width of the soundstage. now it sounds like you' re listening to a push - pull amplifier .
tivoli audio was created for one purpose - to bring beautifully designed, simple - to - use, high quality audio products to consumers at a fair price. the company was founded by tom devesto, a highly respected innovator in the audio industry whose decades - long career includes senior management positions at advent corporation, kloss video and the co - founding of cambridge soundworks. as ceo and head of r & d at his former company, tom was responsible for the development of some of the best selling and most innovative hifi and multimedia speaker products available .

for many, many years the sli - 80 integrated amplifier has been the standard by which all other vacuum tube integrated amplifiers are judged…period! as cary audio’s entry into the magic of vacuum tube music systems, it’s nothing short of stunning. thousands of music lovers all over the world have heard (and seen) the virtues of this spectacular vacuum tube integrated amplifier. before we gloat about the sound of the sli - 80, just look at it. it’s audio jewelry. the open chassis showcasing the warm soft glow of the tubes only enhances its sonic beauty. it is a display piece for any setting, pure and simple .
the sound must be heard to be fully appreciated. as the world’s premier vacuum tube audio company, cary audio designed the sli - 80 to have no peer. the design reproduces every musical nuance and detail in a lush, open and airy presentation while providing bass texture and impact that belies its rated power output. the depth of sound and transparency will cause you to snap your head in disbelief as you look to see the musicians performing in front of you. a pair of toggle switches select either triode mode producing 40 watts per channel of pure class a power, or ultralinear mode which doubles power to 80 watts per channel in class ab. if you’re listening to more subtle music and want to hear all of the inner detail and richness, select triode mode for the most lifelike imaging and tonal accuracy. or, if you want to really let loose, switch to ultralinear mode and enjoy the extra power and dynamics. your choice !
that was almost 10 years ago, when few people (including me) were familiar with set amps. some of those audio writers who were saw sets as anachronisms. or threats—to their own sanity, perhaps ?
wrapped in a premium italian leather strap and carry handle, the beautifully compact andiamo uses easy high - speed bluetooth 3. 0 pairing to transform audio files and streams from any smartphone into fabulous full - range music .
connect the provided bias cord into the bias connection jack. (if you have the cary audio ma - 300 bias meter then skip to step 4 .) it has a 1 / 4 inch mono ‘phone plug’ on one end and a pair of alligator clips on the other end. plug the phone plug into the jack on the chassis. the red alligator clip is for positive electrical connections, the black one is for negative electrical connections on the milliampere (ma) meter .
other cary audio designs do not have an led next to an output tube to show bias levels. the same overall trouble shooting method will work for all of them though. (as well as most brands of tube amplifiers .) replace each output tube, one at a time, until you find the defective tube. when you have a zero reading with a ma meter and the bias potentiometer is set full counter clockwise you are ready to begin to set bias in the amplifier .
sitting on its four conical feet of hefty metal, the 34 - lb cd 303t player is no less impressively built than the more expensive cd 306, and though it lacks the 306' s copper chassis and copper - plated partitions, its interior is similarly laid out, in three sections. the rigid chassis holds a well - organized layout of circuit boards and mechanical parts. the central section contains the transporta sony assembly remanufactured by cary to include a new aluminum disc tray, among other partsas well as the digital input / output and control circuitry. the left section houses the power supply, the right the d / a and analog output circuitry. cary is based in north carolina; wheras cary' s amplifiers are made in america, the 303t is assembled in hong kong .
dennis had was also the founder of the dentron radio company, the founding owner and designer of the ameritron amplifiers, and the amp supply company. dentron radio manufactured all sorts of amateur radio gear; amplifiers, tuners, and for a very short time high frequency transceivers. amp supply company and dentron are no longer in business. ameritron is now owned by mfj enterprises. dentron, ameritron and amp supply company were all based originally in ohio. amp supply moved to cary, north carolina and soon morphed into the cary audio company. amp supply was eventually closed. interestingly, amp supply, dentron and ameritron amps can all be found on e - bay to this very day. amp supply products are not commonly found on e - bay, but dentron and ameritron are very common .
the operating class of the amplifier is determined by how much bias current is present. if there is a lot of bias voltage, only the tube which is driven by the positive going half wave of the signal at any moment is conducting. class b sounds distorted because the point where the signal ‘crosses over’ from positive to negative and begins to drive the other tube is not reproduced cleanly, and this creates crossover distortion in the circuit. as the bias voltage is made less negative, crossover distortion diminishes swiftly, and you are in class a / b2; a little less negative, and they both conduct more, and you have class a / b1. if you go further, you get to the point where both tubes always conduct, making the amplifier work in class a, which has the least crossover distortion and best sound of any of these operating conditions. (cary audio class a single ended output tube designs have ‘0’ crossover distortion due to circuit design and their operating parameters) .
the term bias refers to the amount of voltage held on the grids of the output power tubes. bias is associated with the “operating class” the power amplifier is working in, by design. there are three classes used in hi - fi: class a, class a / b1 and a / b2. class a means that the output tubes are biased so that both tubes are always conducting. in class a / b, the bias is set so that on a signal peak, one of the tubes is off for some part of a signal wave form cycle. in class a / b1, no grid current flows into the grid of the tube, and in class a / b2 some grid current is driven into the grid of the tubes. there are also class b designs where both tubes never conduct current at the same time, only alternately. we at cary audio do not make class b designs. they are frequently used in radio transmission designs, such as amplifiers used for amateur or ‘ham’ radio .
as more audio enthusiasts migrate toward or begin to think about downloading and playing high - resolution audio files via music servers, players sporting multiple dac inputs will become more popular, and single - purpose players will disappear. buying a digital disc player with no dac input today, particularly an expensive one, is a poor investment and a fast path to obsolescence. once you' ve lived with a music server, you' re unlikely to want to return to fumbling with jewel cases; and once you' ve heard hi - rez digital, you won' t want to go back to vinyl. just kidding .
found that the cad - 805c didn' t intrude itself on the sound to the extent that all recordings sounded the same. the main thing was the pleasure i got from listening to the cad - 805c—there' s really no amp that i' ve heard that' s quite like it, unless it' s the $ 40, 000 / pair cary cad - 1610 .
in addition to the usual player controls, from the front panel you can select digital inputs, disc layers (cd or sacd), and your choice of solid - state or tubed buffer / output stage. a small cover plate provides easy access to the four 12au7 tubes (ecc82s can also be used). while cary clearly encourages tube rolling, i used only the stock tubes for this review .
the design features a pair of 6sl7 tubes as the input, pre - driver, and phase - inverter stages, with the input stage buffered and direct - coupled to the phase - inverter. the amp uses svetlana kt99a (6550) output tubes in a push - pull configuration, and employs a custom - designed ultralinear output transformer. in the dark, the sight of the slm - 100' s row of output - tube filaments gleaming off of the chrome was stunning. (a friend refers to them as
the apostles' tongues of fire .
)
preamp. (the cad - 805c needed an active preamp, i found .) speaker cables were the aforementioned xlo ultra 6. power cords all around were the silver - coated copper xtreme from audio magic, which retail for a relatively modest $ 69 each. yes, i did hear an improvement over the stock belden cords i had on hand: more detail, less grunge, cleaner sound .
the cd 303t is an unusually versatile, fully balanced sacd / cd / hdcd player - dac combo with multiple digital inputs and outputs. it can upsample cds to as high as 768khz, and even offers, at the push of a button, the choice between solid - state and tubed output. the cd 303t is the model below cary' s cd 306 sacd professional and costs $ 1500 less. while i didn' t review the 306 (john atkinson did, in the
sacds stubbornly survive, thanks to support from audiophile - oriented labels that continue to release new and reissued recordings on the format, even if the major labels have given up. according to the recording industry association of america, in 2009 the industry shipped just 200, 000 sacd and dvd - audio discs. while i don' t believe the riaa counts sales at the
audiophile
websites where most of these discs are probably sold, even if you double or triple this number, the total is still small .
also like the cd 306, for sacd playback the cd 303t' s clock runs at twice dsd speed, or 22. 5792mhz. four burr - brown pcm 1792u 24 - bit chip sets run in parallel pairs to handle fully balanced, dual - differential digital - to - analog conversion for both dsd and pcm. cary' s dsp - 300 upsampling filter also decodes hdcd - encoded discs, which can deliver 20 - bit performance from cd. in fact, keep your eye on the cd 303t' s hdcd light and you' ll probably be surprised by how many discs in your collection that
qrp is the
art
of making contacts with low power transmissions - typically 5w or less output power. it can be challenging to make contacts with less than 5 watts of power when you are competing with other operators running 1000 watts. some qrp operators build their own inexpensive qrp transmitters in matchboxes and tuna cans or from readily available kits (search for qrp kits on the internet). there are many clubs that design and build such kits and here in the triangle area of nc you can start learning about kit building and qrp (low power operation) by checking out the knightlites club at http: / / www. knightlites. org. qrp operation is especiallypopular with cw operators due to the ability to reach greater distances with cw - and don' t forget that the technician license allows operating cw on some of the hf bands .
slow scan tv is a method of sending still pictures over the amateur radio frequencies. it requires a pc and an amateur radio on each end. typically software is used to
scan
a picture into digital format which is then stored on the pc. software can then send the file as a digital stream to the sound card which converts the data stream to tones which are then sent to audio input to an amateur radio transmitter. on the other end the amateur radio receiver sends the received tones to the input of the sound card which converts it back to a digital stream for the computer software to display as a picture on the screen. this is the same process as sending files between two computers using a modem and phone line. the sound card provides the modem function and the radio replaces the phone line. the fcc limits the bandwidth of this type transmission so it is not fast enough for moving pictures like you get on your home tv, its more like a slide show with pictures painted line by line down the screen in slow motion, but the limited speed means a narrow bandwidth which allows it to be used on hf where using just your pc, some free software, and your hf radio the signal can go around the world to display your picture, or qsl card, to a distant operator. in some areas sstv is also popular using vhf and uhf radios .

the arb - 704 advanced interface is compatible with all common radios and amplifiers even though radios and amplifiers do not have standardized voltages, accessory plugs, or wiring. this interface is designed to work with any amplifier / radio combination .
the input is designed to be compatible with any transmitter or transceiver, and the output is compatible with ac control lines or dc positive or negative amplifier control lines having up to 200 volts peak open circuit voltage and 300 ma of operating current .
amplifiers can damage radios if the amplifier has too much relay control voltage, voltage spikes, or excessive current on the relay control line. such damage often appears as
stuck
or
sticky
transmit relays in exciters or shorted transistors on transmit control lines. in most cases where the radio is damaged, the system transmits normally but the external amplifier stays locked in a
transmit
mode. this prevents receive signals from coming through the amplifier with normal levels whenever the amplifier is in the

ameritron al - 811 linear amplifier gives you plenty power to bust thru qrm .
you get a quiet desktop linear thats so compact itll slide right into your station - - youll hardly know its there... until qrm sets in. conveniently plug it into your nearest 120 vac outlet - - no special wiring needed. three tough 811a transmitting tubes, extra heavy duty power supply, all hf band coverage, pressurized ventilation, tuned input, dual illuminated meters, adjustable alc & more .
the al - 811 gives you 600 watts pep output - - thats nearly 2 full s - units over your barefoot rig. that could mean the difference between hearing ,
youre q - 5 armchair copy
and ,
sorry cant copy you, too much qrm .
now you wont have to stand aside while the
big guns
steal your dx. youll be able to log some of those stations first. going from 600 watts to the full legal limit gives you less than one s - unit increase. but is that fraction of an s - unit worth the 3 or 4 times more money itll cost you? al - 811 gives you a powerful punch at a price thats easy on your wallet .
the al - 811 covers all hf bands. theres no compromise on warc and most mars bands - - you get 100% rated output. you can operate the al - 811 on all modes. get 600 watts output pep ssb and 500 watts output cw. you even get 400 watts on demanding continuous modes like rtty, sstv, fm and am .
first theyre constructed with widely spaced elements that minimize the chance of touching and causing a short - - even if the plate gets hot enough to melt. second they use a directly heated thoriated tungsten filament cathode that prevents the electron emitting layer from instantly stripping off - - even if mistuning causes a sudden, sever current overload. the ameritron al - 811 is excellent for the newcomer because its tough enough to withstand momentary mistuning. and the tubes are so inexpensive that you can replace one for mere pocket change .
the heart of the al - 811 power supply is its heavy duty power transformer with high silicon steel core weighing a hefty 17 pounds. a full wave bridge using 52. 5 ufd of total capacitance (four 210 ufd, 470 volt capacitors) produces 1500 volts under full load and 1700 volts no load. thats excellent high voltage regulation! full height computer grade filter capacitors with screw terminals are used - - not short stubby. light duty soldered - in
high technology
capacitors that cant dissipate the heat generated by high current .
rectifier diodes are rated for a massive surge current of 200 amps. they wont blow even if you accidentally short the high voltage supply. wire wound, 7 watt, 50 k ohm equalizing resistors safely protect each filter capacitor - - not 2 watt, 100 k ohm carbon composition resistors that can open and cause your filter capacitors to explode or fail. the ameritron al - 811 power supply is built tough so you get peak performance year after year .
a pi - network tuned input provides a 50 ohm load for your rig. even fussy solid state rigs can deliver their full drive to al - 811. low loss slug tuned coils - - tunable from the rear panel - - let you optimize performance. high quality low drift silver mica capacitors maintain proper tuning .
the low loss pi - network output tank of the al - 811 has been carefully designated for optimum q on each band and built with quality rf components. the result is peak performance over each band, wide impedance matching range and exceptionally smooth tuning with efficiencies close to 70% . even a 3: 1 swr load wont damage the tubes or tank components. a ball bearing vernier reduction drive makes plate tuning precise and easy .

the ameritron al - 82 linear amplifier is designed to give you years of trouble free service at the full legal output power limit .
an 1800 watt continuous commercial rated hypersil transformer is standard with heavy duty rectifiers in a full wave bridge supply with computer capacitors. two bias settings allow either high efficiency rtty and cw operation at 1500 watts of output at nearly 70% plate efficiency or low distortion 1500 watts pep, ssb or sstv output. silver plated tank components provide high efficiency operation above 20 meters. the pi - l tank circuit permits full impedance matching capability over the entire 160 meter band. the tuning capacitors and bandswitch have a 35% safety factor to virtually eliminate tank circuit component failures, even under adverse operating conditions .
the cooling system keeps the components and tube safely below the manufacturers ratings, even while operating at 1500 watts output with a steady carrier. the filament supply has inrush current limiting to insure maximum tube life. shielding and by - passing help prevent tvi and rfi at the high power levels in the al - 82 .
the al - 82 has two illuminated meters. one is the grid current meter that provides a continuous reading of the 3 - 500zg grid current. this is an ameritron first. grid current indicates proper amplifier performance better than any other parameter. the other is a multi - meter that displays plate voltage, plate current, peak r. f. output power and drive power / alc detector voltage. some competing amplifiers using two 3 - 500zgs cant deliver as much power as the al - 82. why? because the lightweight power supplies they use dont deliver enough high voltage to permit use of the full capability of the two 3 - 500zgs. the al - 82 corrects this problem while still keeping the price at a reasonable level. the power supply in the al - 82 has a commercial service rated 32 pound tape wound hypersil transformer and heavy duty rectifiers in a full wave bridge circuit with computer grade capacitors. no load voltage is 3600 v; full load voltage 3300v - - better than most competing dual 3 - 500zg amplifiers .
examine the features and component ratings of the al - 82 is a well engineered amplifier, built to give you years of power house service .
: 1. 8, 3. 5, 7, 14, 21 mhz and warc bands. export / user modified models include 28mhz .
adjustable pi - network, vswr 1. 2: 1 or less at resonance .
a 50 ohm broadband pi - network tuned input is used. even the fussiest solid state transmitter will deliver full power to your al - 80b. low loss slug tuned coils - - tunable from the rear panel - - let you optimize performance .
a carefully designed pi / pi - l output network using the optimum q for each band gives you exceptionally smooth tuning, extremely wide matching range, full band coverage and peak performance at all power levels. ball bearing venier reduction drives with logging scales on both the plate and load controls make tuning precise and easy. it also lets you rapidly retune to your favorite frequency .
when you first turn on your amplifier, a massive inrush current flows. your house lights flicker as you hear a load
thump
from your amplifier. this terrible inrush current stresses all your power supply components to their limits. your cold tube filament suffers abusive thermal shock. eventually, this massive inrush current will damage your amplifier. the al - 80b special step - start inrush protection stop damaging inrush current. by starting your al - 80b through a 10 ohm current limiting resistor, then shorting the resistor with a relay, the al - 80b gives you a start up sequence thats easy on your tube and power supply components .
excessive line voltage stresses components and causes them to wear out. low line voltage causes a
soft - tube
effect - - low output and signal distortion. ameritrons exclusive multi - voltage power transformer lets you optimize for different line voltage. select from 14 different primary voltages from 90 - 140 vac and 205 to 250 vac. the high voltage secondary can be wired to reduce plate voltage for efficient operation below 400 watts for use outside the usa .
ameritrons dual illuminated cross - needle meters give you four separate meters to monitor your operating conditions - - you can tell right away if something is wrong. grid current, plate current and forward pep output power are continuously monitored to tell you of improper loading and abnormal conditions. the fourth meter can be switched to monitor you 3 - 500 tube dc plate voltage, reflected pep power and the swr of your antenna, alc voltage to your rig and the grid current that starts alc action - - you get a clear operating picture of your al - 80b .
for lightning fast qsk operation use the optional ameritron electronic pin diode qsk switch. get the external qsk switch (
an operate / standby switch lets you run barefoot, but you can instantly switch to full power if you need it. has transmit led; 12 vdc, 200 ma accessory jack; 12 vdc keying relay for solid state and tube rigs; tough, nearly indestructible lexan front panel. shipped with transformer installed and wired for 120 vac. draws 12 amps at 120 vac .

it is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. by using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. keeping two separate amplifiers also makes any inter - channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well - defined. the simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts .
is this extra expense worth it? one listen to the cad - 211fe will convince you that it most certainly is. with over 70 watts of class - a power, automatically transitioning as needed to over 150 watts in class - ab, this powerhouse will effortlessly drive nearly any speaker to realistic live performance levels. it includes a bias meter on the front panel to help you maintain your amplifier at its peak operating level, and offers both xlr balanced and rca single - ended inputs to match your system. fully differentially - balanced construction, zero global feedback, and huge reserves of current and power mean that your system will come alive with all types of music and movies .
