I think if you are going to do any McIntosh repair or refurbashing there are tow choices that I would consider.
FIRST: McIntosh Labs SECOND: Audio Classics. I would try Mc-Labs first. They will do the most thorough checkout and return the peice to original spec. Be prepared to wait though as everything is as mentioned a very thorough checkout. Audio Classics are all old Mc people and can do a near equivalant job. But I think that Mc will actually re-ship in new box as well. They always have my stuff.
They are great people to work with and love their gear as much as we do.
