I could use 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!
