I'm going to try a 10k trim pot in place of the 10k resistor. I've already ordered it along with some other stuff that I needed.

According to the thread this was designed for the radio shack 2n2222 in the black plastic housing. They come in a multipack with two other transistors. I'll...

Help with Fuzz Voltages (Radio Shack Fuzz)
I found the schematic and layout to build this "Radio Shack Fuzz" on another website. I've built the circuit and checked it over about a dozen times...

My plan was to flip it over and poke around with a chopstick to see if I could locate the source of the noise. Before I did that I installed the Weber Signature...

Thanks for the jack setup. That is how I found it on most of the other Tweed amps online.
I fixed the jack and 'viola' everything works. The...

I just found that the connection to the tip of the failing jack is bad at the jack. I've got to run to Lowes, we're painting the dining room, yay . I'll...

Bruce,
Yeah I forgot to scrape off the white primer under the ground points, I'll definitely go back and take care of that.

This sounds exactly like what Dave Hunter does in his two stroke amp which is based closely on a 5F2A? I'm building a cross between a 5F2A and a two stroke...

I guess that I never realized that they were "the little guys". I've seen their stuff and their ads and I just figured that they were a big company....

I've had similar results with them. I bought a used, broken Route 66 pedal on the cheap and when I called them to buy a replacement pot they shipped me a...

I just measured my build (5F2A) and the tube sockets are 2 1/2" on center so they are about 1 1/2" apart. I based the spacing off of my Peavey ValveKing...

Changing filter cap values
I'm building a 5F2A Tweed Princeton project amp with some different mods. I've seen a few threads where folks had changed their filter caps from a pair of...
