ITEM 4.  CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANTS.

     On September 10, 2002, Digital Power Corporation (the "Registrant") engaged
the accounting firm of Ernst & Young, as its independent  certifying accountants
for the  remainder  of the fiscal  year  ending  December  31,  2002,  including
preparation  of the audit and Form 10-KSB for the fiscal year ended December 31,
2002. On that same date, the Registrant  notified Hein + Associates LLP of their
dismissal.  Hein +  Associates  LLP was the  independent  certifying  accountant
previously engaged to audit the Registrant's financial statements for the fiscal
years and periods ended December 31, 2000 and December 31, 2001. The decision to
change  accountants  was approved by the Audit  Committee  and the full Board of
Directors of the Registrant.

     During the  Registrant's  two most recent  fiscal  years and periods  ended
December  31, 2000 and  December  31,  2001 and the  subsequent  interim  period
through  September 10, 2002, there were no disagreements  between the Registrant
and Hein + Associates  LLP on any matter of accounting  principles or practices,
financial  statement  disclosure,   or  auditing  scope  or  procedures,   which
disagreements  if not resolved to their  satisfaction  would have caused them to
make  reference in connection  with their opinion to the subject  matter of this
disagreement.

     None  of  the  "reportable   events"  described  under  Item  304(a)(1)  of
Regulation  S-KB occurred within the  Registrant's  two most recent fiscal years
and the subsequent interim period through September 10, 2002.

     The  audit  report  of  Hein +  Associates  LLP on  consolidated  financial
statements of the Registrant and subsidiaries as of and for the fiscal years and
periods  ended  December 31, 2000 and  December  31,  2001,  did not contain any
adverse opinion or disclaimer of opinion, nor were they qualified or modified as
to uncertainty,  audit scope or accounting principles.  The Registrant requested
Hein +  Associates  LLP  furnish a letter  to the  Registrant  addressed  to the
Securities and Exchange  Commission  stating whether it agrees with the above. A
letter from Hein + Associates LLP is attached as Exhibit 16.1.

     During the  Registrant's  two most recent  fiscal  years and periods  ended
December  31, 2000 and  December  31,  2001 and the  subsequent  interim  period
through  September 10, 2002,  the  Registrant did not consult with Ernst & Young
regarding any of the matters or events set forth in Item  304(a)(2)(i)  and (ii)
of Regulation S-KB.
