Very nice! Sounds great.

Did you insulate the antenna from the enclosure, or is that a plastic enclosure?

That's great! You're welcome. I'm happy to help and glad that you got it working. Would be great to see a build report!

It looks like you used a pair of B2K pots where there should be B25K pots.

Take a look at the intensity and throb controls.

Also, be careful bending the legs of the pots, after 5-10 wiggles back and forth, they'll break.

Nice! Always excited to learn something new! Since I have a signal passing through the circuit and the fuzz side is working, what are the components controlling the theremin(still learning how to read schematics)? Just so I can narrow my search.

I'm assuming it's this section...

Yes, that's it.

Also take a look at R12 R13 R15

RE the 470k resistor between the base and collector of Q1, do you essentially mean solder a resister between these 2 points on the PCB (probably the back as there is no room on the front)?

Yeah, basically however you can get a 470k connected to the base and collector.

When I first typed it in, I wasn't thinking about how to actually physically do this... sorry about that.

Edited to add:

You could also try removing Q1 and running a few wires from the socket to an offboard 2n3904 and a resistor. Either solder the wires directly to the parts, or use a piece of perfboard if you have it. This would be temporary just to see if this solves the problem, and then we can go from there.

I have done some research and it seems the problem might be biasing the first transistor, but I have no idea how do do this. Any help would be appreciated.

Hi and welcome,

Try putting a 470k resistor between the base and collector of Q1, and then biasing as mauman described.

a vintage EHX Attack Decay.

One of the big ones from the 70s? I would love to see some pics!

By the way, I have some more stickers available to anyone that would like to send some out with won auctions. Also, did everyone that already requested them receive them by now?

I would love to have a sticker or two as a keepsake if there are enough available.
