I think the XFMR has four connectors on one end and two on the other end. The bottom two of the four are to be strapped and make the B+ connection for the modulator. The top two, of the four, are the modulator plate connectors. The two on the other end are the secondary winding to go to the final plate circuit.
This is from memory and pictures, so don't take it for 100% accuracy.

I need the pin outs(wiring diagram to pins, etc.). I ordered a manual from the surplus place in Lima, OH. Hopefully I will have QRO on 160 by this fall. BC-339 will be QRO on 75,40, and 20.
