275v=256v
190v=177v
145v=140v
640v=539v
770v=750v
Motorola shows much higher, these voltages are just to low something is not right. Pin 8 of v6 is supposed to be 230v but it’s 110v so if the main power supply voltages are low so is everything else. I had already checked out the power transformer and found it to be fine and 15 minutes is long enough for the thermistor to heat up and I had checked that as well IIRC it was 1 or 2 ohms. And all this is checked with 121v at the outlet.

Try to differentiate between voltages that are all off by 20 percent and those that are off much more.
If all are off by 20 percent then none are pointing you to a particular trouble. The ones that are off by a much greater percent are telling you where to concentrate your trouble shooting. Pick one at a time to work on, and eventually you will fix one and then another.
