Default Linn LK-2(60) One Channel has Failed. Anyone familiar with this circuit design?

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!
