I can't remember where this came from but I was immediately fascinated by the idea of an old, small guitar amp that I could use... restore and use... however I looked underneath and just knew that it was not going to go "out of the box" so to speak, it would need quite a bit of work. I tried it and sure enough all voltages were out, the plate voltages on each side were completely unbalanced, caps leaky, resistors were out of spec and ... Anyway it went into storage while I moved house; and now it's out to be properly looked at but there is not much that does not need replacing, luckily there is not much there, oh the beauty of valve amps! Also I couldn't find a circuit diagram at the time, but maybe now I can, or I'll have to draw it out.
