The Amp Garage

Make a demo video. The better it sounds, the closer you’re likely to get to what you want for it.

Just to eliminate the obvious, but are you sure it isn’t just the buzzy hum of a valve with imperfect heater - cathode insulation, eg fitted into V1? The 2k7 // 0.68uF partial cathode bypass opens the door to that issue. Heater elevation can eliminate it (as can fitting a different valve). Yes, I’v...

I have that same question, why do you want it reworked? What is it not doing to your liking now? I'm in Cairo/greene county, moving to canajoharie/Montgomery county sometime in October so does it have a problem or are you wanting to do it "just 'cause"? i tend to try to talk folks out of unnecessar...

Hello and thanks for reading. I’m looking for someone within a couple hour drive from Albany New York who would be interested in doing some work on my JMP. Long story short, looking to have the "Larry ground scheme" implemented. If this sounds like something you’re interested in, or you have the con...

I built a deluxe reverb clone. Low hum, low noise, but the amp just sounds way too ... punchy is the word that comes to mind. I'm referring more about the initial note attack. It sounds kinda hard for lack of a better word. I'm using an ET65 speaker. Amp is biased around 20 ma. I'm using tung sol 1...

What makes you think that an amp has to being built from a kit? I like how it looks, by the way. Have fun with it! Thats a good question. I just assumed that it was built from a kit because there was no brand on the cabinet. Here is a picture of it. My wife thinks the color is why it was being offe...

it is a blue cloth on it, sort of fuzzy. the output is extremely low on it. there is some oxidation I found on the power supply board that I cleaned off and just starting to look through the amp. Any help would be greatly appreciated. Thanks https://medias.audiofanzine.com/images/normal/polytone-mi...

I'd be interested in this Schematic. I have one on my bench now and the ones I have found online half of the schematic you can not read. Any help would be greatly appreciated Thanks in adavnce Hi, what amp exactly do you have? What kind of tolex? I have a bunch. If you tell me the symptoms I might ...

Far from an electronics expert here, but my 2 cents. It did have a bit of a "splatty" sound to the distortion that reminds me of a tube being hit too hard. Your cleans sound fine, so it makes me think you should try backing down the level hitting the OD circuit with the internal OD trim, and/or lowe...

The Duncan tone stack calculator is online now and has that control. By playing with the values, you can get a lot of interesting curves. Also, at 10 there is almost no insertion loss. Perfect for a tweed amp to add versatility. https://www.guitarscience.net/tsc/framus.htm#RIN=1k&R1=50k&RM=1M&RL=1M&...

Hello everyone! I'm planning to have a new version of the boards produced soon, and I'd love your feedback. What are some things you would like changed in the boards? Are there some errors you found that I can correct in the next revision? Any comments regarding the documentation? I saw some of you...

Thanks Steve. I'll pm you.

I'll pm you. Thanks for the reply,

Hello and thanks for looking. I was hoping someone here could point me in the direction of a tech with dumble experience who can work on a clone I picked up on a trade. Members here are welcome to respond as well. Preferably near N.Y.

PM's preferred.

Thanks again for your time and consideration.
