put them in this pedal.  It's a prescription electronics yardbox.

Nice!  :)  I would be scared I'd damage the transistors during the pull, so I'm impressed. Looks like a Tagboard layout! Love them.

Yes I was very fragile with those trannies.  I didn't pull out or jam it in too hard :) And made sure it didn't get too hot.  That sounds dirty ;)

This is super cool. I have an old retro radio that I want to pull the trannies from, but it is functioning perfectly so i'd feel bad doing it. UGH!

Nice work. That radio case would make a hella cool headphone amp.

Didn't even sockets those boys, you just licked them and jammed them in didn't you?
