Re: Dropping B+ problem! Don and Bruce! I don’t know about this. There’s no sep. bias winding on the PT. I’m aware that there cannot be two CT’s – but it’s a fact that there is two taps grounded on this PT. I guess I could do some resistance measurings on the PT to get some clues on the *mystery* tap. But it works fine now, so I think I’ll just leave it for the time being. Maybe I’ll dig into it later. Thanks all. Lion |

A 2nd grounded "tap" is often a static shield. If you do the ohmmeter test and one of the grounded taps doesn't seem to be connected to any of the others, that's it. Reid |
