I am trying to repair a VAX 4000 power supply. Does anyone have the schematics? I can't find anything on BitSavers and I'm not completely convinced it was even designed by DEC.
The VAX turns on and the status LED stays on F. The DC lamp does not illuminate on the PSU. 5V rail appears fine but there is nothing from the 12V rail. There were some *very* dodgy looking caps which I have replaced, and some *very* exploded MOSFETs, which I have also replaced. If anyone has schematics, or know where I might find them, it would be much appreciated. Thanks, Aaron.
