 I'm not sure. But honestly if you are paying someone else to fix your
amp it is quite unfair to ask that he be tutored for free! I am sure
that McIntosh can fix your amp (probably by board swap so the whole
chassis need not be sent in) or if not that there are talented EEs he,
or you, could hire for a consulting fee. There are many out of work you
know.

 If this were a DIY hobby project and I knew, I'd tell you. My guess is
that unless you can fully backwards engineer the circuit from the
schematic you are going to have to very painstakingly shotgun it (no,
not blast it with a 12-gauge, replace parts and redo connections) or
compare a lot of voltages and resistances to a working unit if one can
be borrowed.
