Before I ship this thing off for repairs, maybe someone can point me in the right direction. It allows me to set the heater voltage and test for leaks, but that's as far as it goes. Go to set G1 voltage and the needle never moves. Power LED is not lit, but is getting 3 VAC. Input to wiper stack is 120 VAC. Output to G1 adjustment pot is 33 VAC, all legs of that pot read 33 VAC to ground regardless of pot adjustment. Reading between any combination of the pot legs is zero regardless of pot adjustment. R7 pot on board is roughly 15 VAC on both legs. Both large ceramic resistors on board are roughly 6 VAC on both ends. Every wire from the transformer is putting out AC voltage, most in the 40 to 60 volt range, one going to the board is 230 volts, which surprises me a little. Solder all looks good, no bulging caps or darkened components, this thing looks darn near new. So, any ideas appreciated as always.
