Yes I think I will have to test the MOVs to really know. Or as you suggested
take a MOV out and measure resistor temperature.

It shows 320pF. Its marked 04UL is supposed to mean 40 joules, although
the
data sheet says 60J.

I want to conclude that the MOV can short pulling over 25ma thru the
1/8th
watt resistor, heating it up, due to 10khz components on the voltage,
and
not an actual high voltage. Would this be a true statement?

Without having the exact waveform, it is impossible to say exactly how
much current the MOV capacitance allows through. I suggest you try an
experiment of removing one of the MOVs and see how much cooler the
resistor runs.

I was suggesting that you might prove that the MOV current is the
cause of the resistor overheating, by removing an MOV and applying the
input signal. I can't guarantee the input will work, correctly, however.
