Tube Amp Archive

:D Bought is amp a couple days ago and can't find a schematic. I get sound but tremelo doesn't seem to work. Big amp has 15" Jensen P15N with output transformer mounted on the speaker frame. Seven tubes -power are 6L6's. I would like to restore this. Sounds good to me now and I wonder how it would s...

If someone had a bunch of old caps would you willing to test them for a fee? How long does it take to test them.Is it worth doing- I guess it depends what they are and what they are worth.

My wifes father has alot of old parts he is willing to give. What is the deal with old caps do the sealed types stay good over time. Which types dry out or become unusable when they get old. He has alot of different types silver mica and alot of ceramic discs as well as some orange drops. He says he...

I have some Nos silver band resisters. Are they ok to use in a Fender type build. I see in some of the original parts layouts they called for 1/2 watt 10% tolence resisters. Any thoughts on this?

Do you guys know of any books or instructions online that explain the process of putting tweed covering on a amp cabinet. I have found a couple pictures here and there but not any real good instructions. I guess what I am looking for is dealing with the corner and foldovers. Thanks

I was thinking of setting myself up to make Hoffman boards because I want a couple for myself. And I was thinking of buying the setup to make them. Most of his board manufacturers sell complete boards but some also sell just the turret board. But I would be using his layout and instructions.

:cry: Wow! Makes you think twice about helping someone out with an amp. Maybe this is why there are so many people selling kits instead of finished amps. I remember reading about kit aircraft and that people were building small planes because of liability issues and the way around it was to sell a k...

Good idea to have someone else take a look just to see you didn't miss something. Thanks

:( Hi-not a fun subject. I am retiring from teaching at the end of this school year and am looking at things to keep me busy and to maybe even make a couple bucks so I can continue to buy my toys. I saw on another posting where a guy said he quit building amps for fear of being sued. Years ago I had...

What is the difference between a Hoffman boards and a traditional layout? Is the circuit the same or has it been upgraded? Thanks for the info.

I see that alot of Ted Webers amp parts are much less expensive than other sites especially his cap prices. Has anyone had experience building his kits? Or should I stick with name parts? Some of his caps are alot less like 20% of a Sprange Atom. I'm a Newbee so what do I know!

Hi- Does anyone know where I can find plans for amp cabinets? I am interested in building some but I don't want to reinvent the wheel if I don't have to. I can get the dimensions off ampwares Fender field guide but a plan would be great some amps have a sloped face and that is hard to tell off a pic...
