Hello colleagues.
I have a problem with the input board (gain control) on a Linn Akurate 3200 (3 chanel x 200W power amplifier).
From one day to another the third channel stopped working and does not emit any sound. I have tried to connect the outputs of channels 1 and 2 to the power amplifier of channel 3 and it works perfectly so I deduce that it is the input pcb.
I have been studying the circuit for several days but being multi-layered, I can not understand the tracks and follow the signal to find the fault, apparently the problem is the opamp Burr Brawn BB2604 but I'm not sure ....
Does anyone have any schematic of this pcb?
Any help would be good, thank you very much
