Hello friends. I have a question....
I'm about to start a 6G6B build into an old junky SS combo I had laying around. This will be my first build from scratch not using a kit. I've already sourced all my parts and stuff.
Anyway I'd like it to have an adjustable bias. I swear I've searched and researched and read threads and seen ideas and I'm just a little confused as to which would be the simplest way to add a pot to the stock bias circuit. I've seen many different ways to do it. I think I've overloaded my brain and given myself paralysis by analysis. Should I use a Blackface style bias circuit? Or where would I tweak the 6G6B bias supply to give me some adjustment? Any help or ideas is appreciated.
I'm attaching the schematic and layout.
