From Pin 7 to foil 6.5VAC steady thru cycle.
This is confusing, pin 7 is supposed to be FLOATING, disconnected from the foil it is USUALLY connected to.
edit TWO: read the whole thread down to my latest post, and JUST find a 1.2 megohm resistor.
edit: did you connect the red dmm probe to the foil connecting r9 and r10, the black probe to pin 7 and then take a voltage reading? Or do a misread and misreport on a current (amperage) reading? The current through the voltage divider bridge is about 21 microamps (0.000021 Amps), so it won't take much extra current draw from pin 7 to upset the voltage divider bridge.
Ok, assuming you meant the foil.
56.3v ac going into a voltage divider: Desolder and checked R9 and R10. R9 694k; R10 1.92M. Re-installed.
That calculates out to 14.947 volts. Correcting for a 10 megohm dmm yields 14.19v, even assuming a 1 megohm ac voltmeter, it's 9.8v
since this is all rather offbeat and cobbled together over many sessions, it's not trustworthy.
Your confidence is precious, and taking the readings should utilize your efforts wisely.
The resistance readings stand for themselves, but I am forced to assume a lot of things.
SO, do this EXACTLY:
You can also set your meter on AC amps and measure the current being pulled from the divider bridge.
connect the red dmm probe to the foil connecting r9 and r10, the black probe to pin 7.
I HOPE your meter can read this. There is little chance of damage IF those are the only two points probed on AC amps,
so when you finish THAT reading, turn your meter BACK to DC VOLTS.
Right now I mistrust the PA3004 chip, but am conflicted by earlier reports of your other unit doing the same thing.
