So I found that C76 was shorted. the screen of the HV Oscillator. it was a maroon drop from god only knows when, someone probably pulled out from their stash and yea. Anyways, it was shorted and it fried the 1500ohm resistor.

I changed those two out, and now I have a raster! However, I noticed after it was on for 30 seconds or so, the resistor in line with the diode started smoking.

Someone took out the original 2.5 Ohm resistor that was in series with the selenium rectifier, and replaced it with a little 10 ohm with a silicon diode.

Its probably apparent that the little 10 ohm 1/2 watt resistor isnt big enough to hold the load of the system, so I wonder originally what its wattage might have been?
