Howdy,
 Am trying to repair a PSU in 1 of my SH-101s. Where in the world does one find diodes 1s1585, 05z36y, 05z11x, 1sp35-200, 1s2473?

Transistors 2sd571l or k, and 2sc1815gr?

Is there an SH user's group out there? Or do I need a cross reference chart to get some more recognizable part numbers for these.

I dont know if there is a short in T1, but there is some resistance on both sides. What the proper values are, I don't know. The R-8 1 ohm power resistor at the input started to smoke, apparently the CPU is done(I have a replacement), but I dont want to put it in until I know the PSU is up and proper. Any help would be greatly appreciated.
