I found one way down state, near Detroit. Can't remember the name of the shop, but after speaking with them we ruled them out. Was a 6 month waiting list. Now, this could be a good thing or a bad thing, if you know what I mean. I was hoping to find someone within driving distance for him, but that proved to be a fruitless endeavor. I used to use Mike's in PA., but he's disappeared. The thing is, I don't think the radio had a major issue. Sounded to me like a cracked solder joint. After two or three key-ups in SSB it would begin to throw a carrier during operation. It blew up his amp. Turn it of and then back on, or let it sit without keying for a few minutes and it was okay again for a very short period. Two or three more keys and we're back to throwing a carrier on SSB.
EDIT: Joanne's was the place near Detroit.
