This is such a simple looking schematic yet its throwing me off and driving my Fluke DMM crazy. I cant get real voltage with the DMM for some reason. The machine does not work but it looks like the transformer is ok. Meter too. When I took a reading with either multimeter across the line voltage or filament voltage the meter on the machine went alive and the needle went all over the place. How does it measure plate voltages?
