I did this last week before finding this group, so no pictures of my soldering. I take it that the purpose is intended to be general electronics?
I bought a used tube amp for $400 (great price, I think), but it was noisy and smelled of smoke. I took it apart to wipe down the insides with isopropynol. I discovered the filter caps were leaking--no surprise really.
$50 of parts later, I replaced the larger capacitors and made a few tweaks to the tone stack. Sounds good for $450.
Maybe I'll post some more stuff later. I'm working on a custom mechanical keyboard with an interesting design. Still working out the kinks.
SAFETY NOTICE: don't open a tube amp without knowing what you're doing! Those big capacitors can carry enough voltage to kill.
