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 

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.
