-30 watts or so (?) into a 15" speaker--likely a Jensen unless it's been replaced since manufacture
-tubes: 2 6L6s, 2 12AX7s, and a 5U4 rectifier
-external speaker output jack on the back panel
-2 channels--clean or else tremolo with speed control, as well as tone and volume controls for each channel (the tremolo sounds amazing, which seems to be common among all amps of this ilk)
-1 footswitch jack to turn the tremolo on and off. My psycho-roommate's boyfriend stole the original footswitch because he was a kleptomaniac asshole, but my ex-husband made me a new one out of an old "teet salve" tin (I was not previously aware that cows' teets required moisturizing).
I'm guessing the circuit is probably similar to a fender tweed amp.
Each 12ax7 has two gain stages, so the firt is most likely 1 gain stage per channel. The second tube then has to have one gain stage for the tremolo oscillator and one tube for a split load pahse inverter, like a tweed deluxe.
The buzzing is either a bum capacitor or maybe a tube heater wire that's too close to the signal path. If you plan on playing the amp, and not just being a collector, switch out all the electrolytic caps (carefully!).
Keep the old ones because in case you ever do sell it, collectors are funny like that.
Cheers.
