Bad Transformer?
#18

I found out you need to not have the power turned on when taking ohm readings, the numbers don't jump as much and i'm getting the correct readings.

So my readings from pin3 to pin 2 is 265ohms. From pin 2 to negative lead of part 61 is 128ohms. From pin3 to negative lead of part 61 is 138ohms. That's 266 ohms together and that's what pin2 to pin3 measure. That's good I think.

My reading from part 64 the ac line conditioners to the on\off switch is around 3ohms, the specs call for 7omes. Not sure what to think there.

I'm probably going to need a new transformer, but I wanted to know for sure and figure that out by the multimeter telling me that there's a problem.
