The problems involve the TSR-500 regeneration circuit board, primarily when it comes to the speed conversion circuitry and the LED drivers.  I have the schematics and manual for the MPC-1000R, but I'm missing the schematic for the TSR-500.  I've looked online and none of the sites with Dovetron info have it.  Does anyone have a copy they could email to me?  I'd also be happy to pay for copying/mailing costs to get a copy.
