When I reassemble it I'll double scope the outputs, but anyone know if one
amp output , to the output board that is, is inverted relative to the other
somewhere.?
For the 1/4 inch outputs , violet,A, L ch is normal sleeve ground but yellow
ch is tip ground. Likewise the paralleled speakon outputs , inner and outer
contacts are swapped between channels.
BTW to work on this amp in 2 halves , you need to fudge a chassis ground
interconnect
