I was wondering if anyone knows where to locate a real schematic for the power supply board (A6) for an 8563E spectrum analyzer?  The line fuse is good, and the input voltage switch is in the right position.  It doesn't even try to power up.  I suspect one of the diodes (CR107) is defective because it reads resistance on both the anode and the cathode.  The service manual only gives a basic block diagram of all the boards.  I need something more to pin point where the short actually is.  If anyone can help it would be appreciated.

I clipped one end of that diode to take it out of circuit and it's fine.  I'm pretty sure it's the transformer.  I doubt I'll be able to find a replacement because this analyzer is obsolete...
