KLH Model 20 Bias and trim adjustments

Recommended Posts

Hi folks,

I picked up a KLH model 20 with AM and will soon recap it.

There are trim pots on each audio pre diver boards and there are trim pots next to the output transistors.

I assume the pots are for bias and idle current. Does anyone know the correct procedure and setting for these?

A real bona-fide service manual would be great but I can only find a schematic and it doesn't say how to adjust or give meaningful voltages.
