My OG homebrew Marshall 50w

[SpiderWars]

This was my first true from-scratch build. Probably around 2000. Not a kit just sourced everything, mostly from Hoffman Amps. The cabinet was made by Armadillo Amps, always thought it was a cool looking smallbox cab. It’s very well made.

Modded to hell and back. Today was bringing it back to stock 50w 1987-circuit glory after a long strange trip to high gain land. It still carries some of the early weirdness but it’s both quiet and loud af. Lots of gain.

I’ll probably try 22n output couplers but it sounds pretty killer as is.

SEXY!

Dang, she's a beauty. I wish I knew how to build an amp like that. I'd love a 50 watt Marshall someday with a nice 2x12 open back cab or ever in a combo arrangement. You's alright Spidah!!!

Great looking amp. Would love to hear some clips!

(Also digging the Shelby Cobra on the lower head in the stack!!)

Thanks for the comments!

22n Mustards are hard to find and super expensive so instead of reducing the output couplers from 100nF (Super Bass) to 22nF (Super Lead) I used 27nF Mustards which were not that expensive. The PI input coupler is 18nF, also not that expensive. The 18nF leans out/tightens the PI a tiny bit and the 27nF gets any lost fullness back. You’d be hard pressed to hear it. But now I don’t have to run the bass super low, I can crank it now.

OEI output transformer since the beginning but this is the third PT. Mercury Magnetics running at 425-430vdc. Dagnall choke. Built when LCR filter caps were still being distributed.
