This is on a 40-190.

I believe someone wired this set wrong and I need to clarify the connection of the CT of the high voltage output from the power transformer. Originally when I got this set the CT was connected to chassis ground. My notes and pictures verify this. I don't know if this is why the rectifier was blown and the power transformer was fried but I don't believe this CT goes to ground in this set. I believe it's B-.

The CT should be isolated from ground and connected to part #60, 150 ohm 1 watt resistor, neg. side of the 12ufd filter cap and on from there. Is this statement correct?

Thanks,
Pepper
