Via EDGAR and By Facsimile (202-772-9218) Securities and Exchange Commission Mail Stop 6010 450 Fifth Street, N.W. Washington, D.C. 20549   Attention:         David Burton       Staff Accountant   Re:    Richardson Electronics, Ltd. Item 4.02 Form 8-K Filed April 7, 2006 File No. 0-12906   Dear Mr. Burton:   We are writing this letter on behalf of Richardson Electronics, Ltd. (the “Company” or the “Registrant”) in response to the letter of the staff (the “Staff”) of the Securities and Exchange Commission (the “Commission”) dated April 11, 2006 regarding the above-referenced filing.   This letter sets forth the comment of the Staff and, following the comment, the Company’s response.   Form 8-K dated April 4, 2006   Item 4-02. Non-Reliance on Previously Issued Financial Statements   1.       Please tell us if your certifying officers have reconsidered the effect on the adequacy of your disclosure controls and procedures as of the end of the period covered by your Form 10-K for the fiscal years ended May 31, 2003, May 29, 2004 and May 28, 2005 and Forms 10-Q for the interim periods ended September 3, 2005 and December 3, 2005 in light of the errors that you have disclosed.

Response: As previously disclosed in its Current Report on Form 8-K filed on April 7, 2006, the Company has discovered errors in financial accounting relating to one of its Italian subsidiaries. As a result of these errors, the Company has concluded that its previously issued financial statements, including those for its fiscal years ended May 31, 2003, May 29, 2004 and May 28, 2005, and the interim periods ended September 3, 2005 and December 3, 2005, should not be relied upon.

As the Staff is aware, internal controls over financial reporting are an important component of the Company’s disclosure controls and procedures. In its Annual Report on Form 10-K for the fiscal year ended May 28, 2005, the Company disclosed four material weaknesses in its internal controls over financial reporting and a plan to remediate those material weaknesses. During the implementation of its remediation plan, the Company discovered the accounting errors disclosed in its Current Report of Form 8-K filed on April 7, 2006. Because the accounting errors relate to material weaknesses the Company has already identified and disclosed, the certifying officers do not believe that the these errors are an indication of any additional material weaknesses impacting the adequacy of the Company’s disclosure controls and procedures.
