DC -
I'm sure you intended to say that you place your "RF hash chokes" in
SERIES with each leg of the NST primary, and not "across" the NST
primary (which would be a dead short across the primary).

Use RF hash chokes across the NST pri between the xmfr and the
Terry filter to delete the RF spikes. Iron core, 2 inch ID PVC
tube, 70 turns #12 AWG on both hot and neutral legs.

Hi Dennis,
I'm using 80 uf per 15/30 so I would try 160 uf. The last time I
measured the PF, I think, it was very close to 1.0 with PFC. I
suspect that you had a bad cap or the voltage rating maybe too
small. My caps are rated for 370 Vac (rms) and I use them on
120Vac line. The NST load shouldn't effect the reliability of the
PFC caps unless perhaps there is excessive RF coming thru the NST.

Smoked my PFC cap last night. Not sure if I had the righty my
for my coil, but it seemed to be working OK, until last
night. Then bang, sizzle, etc.
Could someone suggest the correct value for motor run caps on a
15/60 coil with a 0.03uF tank cap?
Also if any of you have the right PFC caps laying around that
you'd like to sell, I'd be glad to take them off your hands.
