Perhaps I have incorrectly described my observations. I have tried proivde as much information as possible and I appreciate your assistance.The filament leads were disconnected from the circuit. Leads 1 and 2 are green. The center tap is green with a white trace. This is as it is described in the transformer wiring schematic.
These results are with the leads disconnected from the circuit.
Test A had DMM common on center tap.
Test B had DMM common on lead 2.
Test C had DMM common on lead 1.
Test A) 1 2.22V CT 3.36V 2Test B) 1 ??V --> 2
Test C) 1 <--??V 2
Tests B and C are NOT stable. Voltages vary from 1.8-3.2 V
Continuity tests positive from CT to 2. Negative from CT to 1 and from 1 to 2.
Below are voltages referenced to AC ground with the leads disconnected from the circuit.
1 .05
CT 17.49
2 15.08Thanks.
