Exhibit 99.1

          HEI, Inc. Recovers an Additional $521,000 From Former CEO

    MINNEAPOLIS, June 3 /PRNewswire-FirstCall/ -- HEI, Inc. (Nasdaq: HEII)
( http://www.heii.com ) today announced that it has collected an additional
$521,000 towards its judgment against its former Chief Executive Officer,
President and Chairman, and a current director, Anthony J. Fant.  Previously,
HEI was granted total judgments of approximately $2,250,000 against Mr. Fant
in HEI's lawsuit for non-payment of promissory note, conversion, breach of
fiduciary duty, unjust enrichment, corporate waste, and costs associated with
the forensic audit into Mr. Fant's activities.  To date, HEI has collected
approximately $1,400,000 of its total judgment against Mr. Fant.  The
additional $521,000 will be accounted for as income in HEI's 4th quarter of FY
2004, which ends in August 2004.
    The additional $521,000 was recovered through the court-ordered
liquidation of Mr. Fant's shares of HEI stock.  A registration statement for
the resale of these shares was filed with the Securities and Exchange
Commission on May 31, 2004.  It is believed that Mr. Fant no longer owns any
shares in HEI. Although Mr. Fant still maintains the title of a director of
HEI, he has not participated in any board activities since June 2003.  In
addition, the board of directors of HEI has repeatedly requested the
resignation of Mr. Fant from the board, but to date this request has been
ignored.
    HEI continues to pursue collection on the judgments in the normal course
in Minnesota and other states, where it is believed that Mr. Fant may have
non-exempt assets.  There is no assurance that HEI will be able to collect the
full amount of its judgments against Mr. Fant.
