No R speaker nor R line out, L &R phones out seem ok, as does the speakers
on/off sw. Amp hiss from the R speaker only, L is fine.
I got inside this 7 octave thing without breaking any foil ribbons. The
phones input socket switches seem ok, so does the line out sockets. But the
Line-In Left/ Mono input has a bad bypass switch. Although it is in a
position that would suggest a Ring contact it seems to be a tip contact
switch, difficult to trace the local traces as vias etc.
Anyone know if the problem there would cause the loss of one channel. As
difficult to "bench test" this sort of item, any other areas to look at
before some sort of reassembly?
