I have a scan of a schematic for a HR40-5.
It has a 60Hz switching pre-regulator that's a nightmare.
If you can't find the right one, I can email this one.

I would appreciate it if you could send along the schematic you have. I rea
lly don't mind a challange. Hopefully the schematic is similar. I suspected
 it was a switcher as the transformer looked small for 30-40 Watts. Please  
send it to chrmiss<remove>@gmail.com. Plan on starting with the caps and th
en maybe one of the power semiconductors.
