Default Service manual / schematic / help - Protek P3502 (Hung Chang)

I hope this is the right forum. Need a little help...

I have this Protek P3502 (aka Hung Chang 3502) Oscilloscope that has a couple of power resistors that got cooked.

I don't have the service manual or a schematic so this is a nightmare to figure out.

Anyone have a schematic or service manual?

Btw, I think these resistors are part of either the horizontal or vertical amp (ultimately the signal finds its way to the tube and it looks sort of like a symmetrical circuit... ???)

Thanks!
