I bought a bunch of junk

There's a list of most of the audio stuff.

I'm not looking to start an online store or do a bunch of shipping, but if there's something on that list that you need to finish a project, it's not available other places, and you're a forum member whose posts amuse me, there's a decent chance I'd be willing to drop a couple pieces in an envelope for you.

"Hmmmm for this build I still need a 100n cap, a 33n and a 680n ...
1, 2, 3, 4, 5 ... 97, 98, 99... 100 1n caps.

*sigh*
1, 2, 3 ... 98, 99, 100 6n8 caps. Good. 680n
Only need 10 of these in parallel, but with tolerance drift I've still only got 29n7; can throw on another 3n3 — that's 1,423 of the 3n3 caps still in stock... I gotta find a way to use more of these guys up.

Hmmm I need to order more 1590DDs for these Fuzz Face builds...
"

*sigh*

Feral Feline you SOB!

I don't know much about power transistors, but where would you use a PNP power transistor?
No idea! 🤣

I replaced a few power transistors in a PA amp a while back but I don’t know if they were NPN or PNP.

All that stuff I bought came from a place that makes fancy microphones, and a lot of it made sense for that application - special low power, low noise stuff, but the power transistors are a mystery.

I guess they might have been building gear related to testing mics too?
