Unfortunately, I forgot to take pictures of the chassis after working on it . . . but I replaced all the leaky coupling caps, the electrolytic caps, installed a 3-prong cord, fuse, and installed several input options, including a stereo 1/8" for plugging in an iPod. I connected a relay "sense" circuit to the 1/4" guitar input, so that when a guitar is plugged into the amp it automatically switches the output from the internal speaker to an external speaker jack (with a switched dummy load resistor, of course). The owner of the amp restored this beautiful G.E. radio cabinet to house the amplifier.
