RE: To Terry or Not To Terry ?

Thanks Terry

I hope it is better than a NST, the secondary wire is heaver than a NST
, no centertap but I think I could add one if needed as it has two
windings and one output post on each winding , they are tied together
with a wire and that is where I think a center tap would be. It was a HV
supply transformer from a laser unit.

Hi rich,

The filter was only designed for NSTs and their problems.  Assuming your

transformer is basically better than an NST, then just safety gaps
be fine.
