Good point Jim. I missed that. In that case likely the fault would be the
bias control on the Bias/QSK board.
Without doing a magnetization test, as the primaries will show a very low DC
resistance, a primary short would be difficult to determine. Of course if
the primary is shorted to the frame, a DC measurement would show this.
Sounds like further and detail trouble shooting might be in order.

Something about this does not compute. The original post said that he
didn't blow fuses until he went from standby to operate. If the
transformer were shorted, I'd expect a fuse to blow with first power
applied to the transformer.
