I live in San Diego, and I have a C28 with a problem in the low-level inputs. One channel is out completely, and the other has a lot of static. I have taken it back to one repair organization three times. It works for a couple of days, and then starts to resume its bad behavior. Any advice on what is wrong? Is there a service center in San Diego where the technician will talk with client? The place I have used will not divulge any information. Thank you.
It is obviously time to find a new service shop that will talk to you. I have no idea who to send you to in your area. My best advice is to contact McIntosh or call Audio Classics in New York.
