  1. 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. Thx, Techfixer
