Item 4.01.  Changes in Registrant's Certifying Accountant.

(a)  On September 1, 2005, the Audit Committee of the Board of Directors of
Tech/Ops Sevcon, Inc. (the "Company") voted to replace Grant Thornton LLP
with Vitale, Caturano & Company Ltd. as the Company's independent registered
public accounting firm, effective immediately.

Grant Thornton LLP's audit reports on the consolidated financial statements
of the Company and subsidiaries for the fiscal years ended September 30, 2004
and 2003 did not contain any adverse opinion or disclaimer of opinion, and
were not qualified or modified as to uncertainty, audit scope or accounting
principles.

During the Company's two most recent fiscal years and through the date of the
Audit Committee's action, there were no disagreements between the Company and
Grant Thornton LLP on any matter of accounting principles or practices,
financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to the satisfaction of Grant Thornton LLP,
would have caused Grant Thornton LLP to make reference to the matter in its
audit report; and there were no reportable events, as defined in Item
304(a)(1)(v) of Regulation S-K.

The Company provided Grant Thornton LLP with a copy of the foregoing
disclosures and requested that Grant Thornton LLP furnish the Company a
letter addressed to the Securities and Exchange Commission stating whether
it agrees with them. A copy of Grant Thornton LLP's response is attached as
Exhibit 16.1 to this Form 8-K.

(b)  On September 1, 2005, with the approval of the Company's Audit
Committee, the Company engaged Vitale, Caturano & Company Ltd. ("VCC") to
replace Grant Thornton LLP as the Company's independent registered public
accounting firm.

During the Company's two most recent fiscal years and through the date of
VCC's engagement, neither the Company nor anyone on behalf of the Company
consulted with VCC in any matter regarding either (A) the application of
accounting principles to a specified transaction, either completed or
proposed, or the type of audit opinion that might be rendered on the
Company's financial statements, and neither was a written report nor oral
advice provided to the Company that VCC concluded was an important factor
considered by the Company in reaching a decision as to the accounting,
auditing or financial reporting issue, or (B) any matter that was the subject
of either a disagreement or a reportable event, as each are defined in Items
304(a)(1)(iv) and (v) of Regulation S-K, respectively.

The Company undertook a review of its independent auditors as part of its
ongoing efforts to reduce operating costs and expenses. The Company's Audit
Committee selected VCC based, among other things, on the fee estimates
provided by VCC and the closure by Grant Thornton UK LLP of its office in
Newcastle, near the Company's UK facilities. The Company expects to lower its
audit costs as a result of the change in accounting firms.
