Vacuum Tube Amplifier

After several weeks of fiddling and some exciting pyrotechnics, the circuit worked (due to the labeling on the output transformer it was impossible to tell if the feedback was positive or negative :) -- this is also the explanation for the name of the amplifier). I then added a reverb circuit and cabinet of my own design to finish it off. It sounds pretty good. You have to turn it up quite loud to get the 6L6's to distort.
