Actually the resistor was mounted on the top of the 5kV Doorknob capacitor and it measured 50 ohms shy of 1 Meg Ohm, so it drifted down a little bit over the years but its still within tolerance suprisingly enough.

which means that it could be the 5kV doorknob capacitor we'll have to look at next...

Dang. How'd I miss this post earlier? (Thumps forehead)

Is it honestly labeled 5KV? It should be rated at least 20 KV.

Temporarily disconnect this cap and see if the HV comes up.

It's the original doorknob capacitor to the set, look at the parts list in the Sam's for this set, it says 500 mmf 5kV.
