Good read. Always admire a hacker like myself. Never messed with tube amps though.

I TOUCH THIS HUGE BLUE THING AND MY GOD, IT WAS LIKE BEING PUNCHED IN THE CHEST BY MIKE TYSON
Here's the funniest part.
Luckily, I stumbled onto the Variac transformer soon after. I'd bought another Marshall amp, and I had no idea that it was actually a European model. I plugged it in, and I'm waiting for it to warm up and thinking, I got ripped off here, there's no sound coming out! Pissed off, I came back an hour later to give it another shot. I'd left the amp on the whole time. I didn't know it was set on 220, so when I turn my guitar on it sounds like a full-blown Marshall, all the way up, except really, really quiet. That was when I realized there was something going on with the voltage. There were these cheesy light dimmers in the house, and I hooked it up to one of those. Of course I wired it backwards and shorted out the whole house, so I went down to a place in Pasadena and asked if there was some kind of industrial-size variable transformer that would let me adjust voltage, and they introduced me to the Variac. It's just a huge light dimmer. I plugged it into the amp and controlled the voltage from that. That became my volume knob. I would set the voltage depending on the size of the room we were playing, getting all that feedback at any volume.
