Everybody make a Ruby Amp!
It's a nine-volt, 386-based amplifier that actually kind of cranks. It has a gain pot and a volume pot and can be used as a headphone amp...and the parts, all together, only cost like ten dollars. You might well have them in your workshop.

Mine's in a homemade pine cab, covered with crushed velvet. The speaker is a 6" Jensen MOD ($15) though I have made one with a 1" Kobetone speaker (built into a Hammond stompbox case!) from Mouser and it almost sounds kind of OK! The sound is akin to a Tube Screamer with a speaker stuck on it. There's also a mod that is supposed to make it sound like a Bassman. It doesn't, but it's got some of that tubey "sag" and really reacts strongly to picking strength.

I just grounded everything to the board ground...input, volume pot lug 1, 9v-, and there's no significant noise. The first time I did it I forgot to send lug 1 of volume to ground, and it was really noisy and the volume didn't work. That's not marked on the layout diagram, they just figure you know.
Stereo Ruby
That's one fine looking amp!
I made a stereo one to power two separate cabinets. It's pretty loud. (sorta ugly, though.)

not to worry, just keep tracking....
