Title: Laney Pro-Tube 50
Post by: h4ck.b0x7 on June 23, 2017, 09:47:23 pm

I'm replacing tubes and biasing this amp. This is the Pre-AOR model. While I have the chassis out I'd like to replace the electrolytics.

Does anybody know where I can find a schematic?

Has anybody serviced one of these before?

Any leads on finding caps?

since you're just doing Ecaps and bias supply, I'd start with the AOR50 schematic and note "oddities", caps are easy, Dougs selection is good, mouser etal
