Looking for good repair shop in Chicago

I have had very good luck with Stereo Exchange in Lincoln Square neighborhood of Chicago. Dave has repaired my very complicated Conrad Johnson Evolution 2000 hybrid amplifier and my Antique Sound Labs Flora that had shipping damage. They have a very cool vintage collection of gear so I would have no doubt that they would be very much at home with your vintage Mac amp.

Can you spend extra shipping to Tenessee.Terry DeWick is familiar with almost all mcintosh gear.He just did my mc-225 back to life and i will send my other one for minor repair and serviced.Every one knows him except he is that far from you?....I shipped my mc-225 from California,Sf all the way to Knoxville.

Check out Deltronics - they have two locations: one in Chicago the other in Woodridge. I had them do a little work on a Sonic Frontiers Line 1 preamp a couple of years ago and they did a good job for a reasonable price.

A dealer friend from the Northside sends most of his stuff to Deltronics, he says they do good work. I have never had anything repaired at Stereo Exchange but I drop in occasionally and they always have some great vintage gear. Nice guys too.
