Tube Amp Archive

Which of the several Master Volume designs did you use? Pre -PI? Post PI? And how do you like it? Grats on the build! That looks vastly better than my first, umm, several builds. Thanks man! I've used Pre PI, read a lot and I think it's work better for me. https://robrobinette.com/Generic_Tube_Amp_...

Yeah that picture with the 335 is killer. @Alextsayun please elaborate on the master volume if you will. It's not 335, it's 330 :) About master volume, from my perspective for Princeton better works this mod — PRE Phase Inverter Master Volume https://robrobinette.com/Generic_Tube_Amp_Mods.htm#Pre_P...

Thank you my friend!

Frankly speaking it's not a real black tweed, it's a yellow tweed painted black acrylic over the top and after that lacquered.

hahah, I'm not a big fun of black, but ...

And it's ready to use and guys it sounds amazing, really

Ok, I've lacquered cab using german shellac and added a few mods

Bright switch to volume pot



and the Master Volume for the bedroom use

Put reverb tank to the case



and all other parts to cab

First "ON" oh my god it's working

Put the handmade label so as not to forget where the valves stand

2/2 parts ready to use

The difficult part for me is to wiring all this spaghetti, oh "so much fun"

Trying to check "the view"

Next step is assembling main board
