thanks a lot,
Saturday Audio Exchange in Belmont is a reliable repair shop.
You might try Decibel Audio on Milwaukee. Their prices are quite reasonable.
I've had good luck at Midwest Audio in Des Plaines with two repairs,
Deltronics located at 2003 W. 75th Street in Woodridge. The owners name is Mike and the business phone number is 630-910-6630.
You might try the Audio Shop in Racine, WI

It looks to be the current location of a guy that has done work for me in the past...nice guy & very good work. If it is..he had a shop inside Al's Stereo in Racine up until Al's was sold and moved/closed.
thanks guys will try those shops.
