My amp's one channel has failed. Reading no DC Offset(-60 mV very close to the working channel), just very low level hiss/hum (like working channel when there is no signal).
I replaced all transistors & diodes including the Output devices (TIP35C & TIP36C) on the non-working channel but made no difference.
All the DC voltages seem to be the same as the working channel as well.
I understand that the protection circuitry consists of a couple transistors (A93 & A43) and a couple of caps that charge up when there is a fault.
Is anyone familiar with this circuit?
Thanks in advance!
