Just discovered this place. Reminded me of my 1st amp: I was 16, had no clue or money, but a cheap japanese guitar and a soldering iron. I searched until I found a ca. +9V contact joint and attached a 1 transistor preamp to it (free floating). Plugged my guitar in, recieved no electrical shock (and therefore survived) and had lots of fun. The radio survived the torture, too, don't know what has become of it.
