My first recapping of a CD player went badly: at first I had no right channel, but fine digital out. Then the drawer wouldn't open or shut, but spin fast counterclockwise for five seconds then, with another push, spun more normally clockwise for a second or two, repeating this for more pushes, counter reading eight zeros or two zeros, all repeatable. I changed to newer belts (this is a Denon 1600, virtually identical to the Denon 1500 II), but that made no difference.
Paul Porcelli, the Turbo DAC maker, suggested to me that I may have blown or burned out a regulator. This player has five, each with its own heatsink, as usual. I've measured VDC between the outer (of three) legs of each, and get repeatable results. But is that the right way to check if they're okay? I bet someone on this Forum can tell me--and maybe even offer other useful advice. As usual, I'll be very grateful if so.
