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.

Bob, K4TAX
