PT with multiple secondarys question

Yes, just make sure the down stream components (pot and resistor) etc are connected otherwise the cap will see the full rectified voltage of the 330 / 400 (which ever is selected) vac windings.

I haven't seen it done before, but a voltage divider could be placed in front of the cap to protect it. This would only require adding a resistor across the cap to ground.

That's a 350V cap, even if it gets hit with 400 briefly it should survive.

Plenty of Marshalls have been made without any such precautions, too!

I'm not terribly worried about it, not like when I accidentally put 600V across a 350V cap...can you say BOOM

In any case, thx for the help. The circuit is in there, I'll let you know how it works out.
