Al, sorry about the amp.
My advice would be to look for a local tech, I am sure there are many. I would look at a local high-fi shop. Some have repairmen. I used one at a place called Brooks Berdan (here in LA) once for the Audio Note.
My amps seem ok (fingers crossed). I do however have one casualty, the HE90 gets static on the right side when i jiggle the wire going into the connector (amp side). I guess several people were wondering why it is folded in half entering the connector and were trying to fix it.
