     The registrant hereby amends Item 8 of its Annual Report on Form 10-K
for the fiscal year ended September 30, 1998 by revising the Report of
Independent Public Accountants to expressly cover the consolidated
statements of comprehensive income included in Item 8 as follows:



               REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Tech/Ops Sevcon, Inc.:

We have audited the accompanying consolidated balance sheets of Tech/Ops
Sevcon, Inc. (a Delaware Corporation) as of September 30, 1998 and 1997,
and the related consolidated statements of income, comprehensive income,
stockholders' investment, and cash flows for each of the three years in the
period ended September 30, 1998. These financial statements are the
responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based upon our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Tech/Ops Sevcon, Inc.
as of September 30, 1998 and 1997, and the results of its operations and
cash flows for each of the three years in the period ended September 30,
1998 in conformity with generally accepted accounting principles.

Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule listed in the index of
financial statements is presented for purposes of complying with the
Securities and Exchange Commission's rules and is not part of the basic
financial statements. This schedule has been subjected to the auditing
procedures applied in the audit of the basic financial statements and, in
our opinion, fairly states, in all material respects, the financial data
required to be set forth therein in relation to the basic financial
statements taken as a whole.
