RE: FILT1.JPG (Was Terry's NST Filter Network)

I think you will have a problem using the resistors that you described.  The
resistors in the filter network will develop 10's of kV across them.  The
aluminum heat sink on your resistors will reduce the maximum voltage the
resistor can withstand, and you will get arcing from the leads to the case.
You have to use air-cooled ceramic resistors.
