Tube Amp Archive

Wow. My first 5E3 "ish" build 20+ years ago was from cobbled parts and iron. I never got picky about an exact much of anything and it turned out great. Maybe I just got lucky. Looking back at these old pics I start to cringe knowing what I know now ;) Cool thread. I will be watching and as always, c...

Soldering is an art form of sorts that takes experience, practice, and even better, some amount of in person training before diving into a project. I would suggest you watch some tutorials and practice on a junk piece of equipment or make a practice circuit board. No offense but the solder work I am...

I have successfully made many 18 watt Lite IIb amps using Hammond AO-35 organ amps.

Thank you for the heads up and thank you for reinforcing my disdain towards filmosound amps . I swore off of them a long time ago. Total PITA as far as I am concerned. They are a rats nest shoehorned into a tiny box. Gutting them and starting over is a good idea. What circuit to you go with upon reb...

Nothing wrong about getting a shiny new one. For $25-$50 you'll find not so shiny but fully functional on FB Marketplace. Fiberglas dust is very bad for your health. Once you breathe it in, it stays there forever. Please use dust collection when drilling your boards. From a Google search: AI Overvi...

Yes, plenty of iron on those.

I have built a few Brown Note Lite IIb amps out of them. Myself and many others liked them.

Playing aside, there were some clean tones that sounded reasonably good, and in skilled hands, would shine through. But then he turns it up, and the harshness shows up. It could also be blocking distortion Could also be a crappy mic on the cam. I have had that trouble before. Sounded great in perso...

I was REALLY surprised to see that he wasn't flaring out the back side of his turret lugs. Probably OK for an amp that isn't regularly on the road though. Loved the carbon fiber stuff! Anyone here playing around with that medium? Thanks again, Dave O. I was thinking the same thing about the turrets...

You will not get any reading on your DVM if the speaker is blown. Generally speaking this is true but not always. I guess it depends on the definition of "blown". If you "bottom out" the voice coil in the magnet and cause a mechanical separation and the speaker still makes sound but rattles and pop...

Original thread is here https://tubeamparchive.com/viewtopic.php?t=25701 It's a Gibson EH-125 but with a different tube layout than any others that I have seen. So I replaced all of the caps which was really straight forward. I also added a 3-prong checked and swapped tubes, cords, etc. The sound I ...

I've got a callous on the pinky finger of my picking hand from the use of volume/tone pots! :P No Fargen stomp boxes for me! Although I do dearly love my "tweaked to personal taste" wah-wah! :mrgreen: Gene You have what on your what? I have a roll of duct tape holding together my reading/soldering ...

You can make a pedal that is nothing more than a volume pot. Kick it "on" for rhythm playing, bypass for leads. I have some salvaged organ parts around here somewhere. Volume pedal from a Hammond organ. Mechanically it works about like a Cry Baby. I save everything for parts down to nuts and bolts....
