Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

well phooey!

What started out as a simple little project to convert my old 300B amp into a test mule has blossomed into a major undertaking. I really do want to have the B+ adjustable for trying different designs, but even if I was willing to pluck down the $100 plus they want for one skookum enough to do the trick, there is no room on the old psu chassis for it. I suppose I could build a variac module and use that, but I already have a good variac.
Soooooooo it looks like I will have to go with 4 chassis instead of just two; one for the B+, one for the filaments and two others for the right and left channel tube and opt modules. Fortunately I have the last two already made from a previous breadboard project, so that will help.
Thought I would make one last plea for any other ideas anyone might have that would allow me to use just the two chassis from the old amp instead.
