Try contacting ARC directly, they should be able to provide it to you possibly even as a pdf by email..

Hi Zeferino,

Can't help you with the schematics but i'm also a CA-50 owner.
Very fine amplifier! Have you tried some tube rolling for finetuning te sound or still the sovteks and svetlana's ?

I would appreciate a copy/scan of the schematic from you when you have it...very helpful in case there is a problem. So far not with my amp. After 6 years still the first set of tubes in it! (and they still measure OK)...

greetings,
Sander
