Germanium bass pedals?

[matmonster58]

Ive just come into a pretty large stash of TI 2n404a transistors.

What projects should I add to my list?
Also can someone recommend me an affordable transistor tester?

I definitely want to build a dizzy tone/buzz around
I have an npn version on strip board right now that is not currently working

I'm going to reply to this thread with ideas I've found in case anyone else wants to reference it in the future

@matmonster58 — Do you have a Redstone PCB source?

Ahh I see Fuzzonaut has built one on a DEFX PCB!


Cheap tester: TC-1 manual PDF

Not sure if it can test for leakage, I vaguely recall it does not according to some posts I read somewhere on the forum.

TC1 users, some questions for you

I just ordered a TC1 tester--my intent was to get ballpark measurements for some Ge transistors. I'm pretty frustrated with it though: I'm finding it doesn't detect JFETs, it doesn't detect Ge transistors, and it can't measure detect several types of high-gain BJTs (I'm getting no readings on...

Looking for a transistor tester

Finally got my small bear order in and need to measure pinout, hre , and leakage. I've got npn and pnp for both silicon and geraniums. Is there a cheapo one from Amazon you guys can recommend? Thanks

The strip board layout is on tag board. It's nice to know a PCB exists though
