     Trio-Tech International, a California corporation (the "Company"),
registered on Form S-8 Registration Statement No. 33-33095 an aggregate of
500,000 shares of the Common Stock, no par value per share (the "Common Stock"),
of the Company issuable upon the exercise of stock options granted or to be
granted under The Trio-Tech 1989 Stock Option Plan (the "Plan").  In 1997, the
Company effected a three for two split of the Common Stock.

     Promptly after the filing of this Post-Effective Amendment No. 1 to Form S-
8 Registration Statement No. 33-33095, the Company intends to file a new Form S-
8 to cover, in one registration statement, all shares of the Common Stock
issuable upon the exercise of options granted or to be granted under various
Company-stock option plans in order to streamline the Company's filings.

     The purpose of this Post-Effective Amendment No. 1 to Form S-8 Registration
Statement No. 33-33095 is to deregister an aggregate of 7,500 shares of the
Common Stock covered thereby representing shares covered by the Plan which have
not been sold upon exercise of outstanding options granted thereunder (and after
giving effect to the above-described stock split).

          The Company does hereby amend Form S-8 Registration Statement No. 33-
33095 by removing from registration thereunder an aggregate of 7,500 shares of
the Common Stock registered thereby for issuance upon the exercise of
outstanding options granted pursuant to the Plan.

Securities Act of 1933, as amended, and the requirements of the Securities Act
of 1933, as amended, the Registrant has duly caused this Post-Effective
Amendment No. 1 to Form S-8 Registration Statement No. 33-33095 to be signed on
its behalf by the undersigned, thereunto duly authorized, in the City of San
