Tube Amp Archive

Hey Guys. I've been working hard on my build and finished up the wiring this morning. This is my first chassis punch and I changed my mind a few times...forgive me if its a bit messy. I followed Tino Z's schematic and layout with a few small changes. I plugged it in this morning and the pilot light ...

I too found a run-of-the-mill Vintage 30 to work REALLY well with this amp. Very full, warm, punchy, and balanced. Not bright or shrill at all. With an archtop, you hear the guitar very clearly. Smoky and jazzy, but not in a muffled way as if the tone were rolled all the way off. Comfortably loud. ...

M Fowler: Your voltages look right in line with Tino's. I have that book as well and I'm trying to decide if I want to build it to his specs or go with the original B+. Does yours still have the classic CC tone? What speaker did you use? Colossal: Thanks for that. I hadn't seen that version of the s...

Great stuff guys! Dave: The LC feed goes: PT > 5AR4 Rectifier > Choke > Reservoir Cap? Colossal: I think I understand what you're saying, but I'm not positive. Do you have a photo or layout handy? I've looked for pictures of your finished build but haven't had any luck. I might be searching the wron...

M Fowler: Thanks a ton! What did your B+ end up at? Your build looks great too, I'll be referencing it a bunch. Did you punch your own chassis? Colossal: I definitely want to use a tube rectifier and be somewhat historically accurate. I won't be using a field coil speaker but would love to have the ...

So I should look for a PT with something around 400 on the secondary?

What transformers did you guys use in your builds? David you used an all TP25, but are there better options? Do you guys have a recommendation for a low voltage secondary PT? Is it better to get a higher secondary and drop it with a Zener?

Thanks.

Thanks! I did a bit of fruitless searching but I must have done something wrong because those results didn't turn up.

Hi all!

I'm a newcomer to the forum and a hobbyist builder. I've built a number of tweed circuits and I'm thinking of a Gibson EH 150 next. It has been tough to find info and other builds. Any one have experience with this circuit?

Thanks!
