Exclamation Bias procedure + Schematics cta 501

Is there a link on the internet or someone that I can contact about the correct Bias procedure for a copland 501.

and also i searched the net and I can download a schema for a copland cta 401 amp, but not the exact one for the 501.

Thanks in advance,

Hi Bas

I am also looking for schematic for STA 501, but more important the wiring details for the mains transformer.

If you know which colour wires go to the relavant pins on pcb, or know where I can get the info please.

Best regards
