OK, Rob, this has become a private war for me. We gotta fix this thing. I think I have some ideas but need more info. Can you answer the following 5 questions?

1. Does the rest of the power supply (A and C voltages) work?
2. Please read off the voltage labels for the taps for the output that are stenciled to the B+ Output edge of
the board. Is the highest B Voltage 180V?
3. What is the value (uF and Working Volts) of C3?
4. Did you get a package insert or instruction sheet for the transformer?
5. Are the wires numbered?

The following is a link to an instruction sheet for this transformer:

This transformer is essentially an Isolation transformer with 2 primaries and 2 secondaries. The wires are supposed to be numbered. What is supposed to happen here is that Line 1 connects to Line 5, and Line 2 connects to Line 6 on the primary. Line 8 is supposed to connect to line 11 on the secondary. When you connect the primary to 120V, there will then be 240V between 7 and 12. Test this off board. If you get zero volts but the transformer does not get hot, then the transformer is not phased correctly. The transformer will "buck" itself and the net power will be Zero Volts.

If the Highest available B+ voltage is 180V and C3 is a 300 or so working volt cap, then the primaries are supposed to be in parallel and the secondaries are supposed to be in series and must be in phase.

Let me know. Good luck.
