Well working order and within spec are two different things when it comes to 50 year old electronics LOL... Some caps die pretty fast while some of those older blue mallorys seem to last forever. You just have to measure and check it out. Unlike out vintage guitars, old electronics just deteriorate.

Yes they are separate circuits and for sure different tone stacks. However, both channels do share the same power section/supply. Everything is brought together. Fender amps that have 2 channels like a DR or any AB763 have two tone stacks as well and are brought together through the mixing circuit into the power section. This has been around many years. For you Marshall project think about having two circuits independent that share a common power section. I no longer build custom amps like you are asking about as the R&D is just too time consuming and am already VERY busy with the stuff I build. Good luck and I hope this helps a little. Cheers

Not sure buddy, I was just noodling around a but

Thx man. It hurts me pretty good to try but I'm gonna keep after it

I used a Skat Blaster with glass beads. Cheers

@@65Corvette Thanks, did it get a rust treatment as well?

@@DuyNguyenYT Nah, it is cast and was powder coated an hour later and sealed inside and out

Hi There, The "Marshall Side" is a different circuit on the left channel. The tone stack is a cathode follower as opposed to the way Fender did that. So yes there is a master but its not just adding a master, there is way more to it than that sir. Cheers!

12" speaker. And yes, my amps do have adjustable BIAS and is easy to set with minimal skills. Cheers

Hey there, the speakers in this particular amp are 2 - Celestion Golds 10" and 2 - Celestion Cream backs 10" - All 4 are 8Ω for a total impedance of 2Ω. I have used Webers in my Uncle Larry amps and IMHO the golds are far superior. Out of the hundreds of UL amps I have shipped only 2 had Webers which were later swapped out by the owners I am told. Cheers

@@65Corvette Thanks Mike, I had a buddy that play one of your amps, I guess it may have been the Tremendous Reverb, I think he said it had one of those Eminence EV speakers in it, is that your favorite now for the blackface stuff?

@@taggmanibanez My speaker choices depend on what amp I am building and what a player intends to do with them. There is no right or wrong choice as it really is subjective to each player, style, and what they want to hear. Cheers

HAHA, no way man. That is a hand wired tube amplifier built at p2pAmps.

Instant subscribe! 😁

😀 I am here when you're ready - Cheers!

I got what I got. A silver twin. An old Peavy 2 12. A couple of crate 2 10's And an amp I bought for a really great guitarist friend that took his life Fender hot rod. I need a music room.

That is a P2pamps bad dawg. I am the builder
