<< Ed,
Running _any_ cap at higher break rates in Tela Coil service will
certainly stress it more. If it has any internal weakness (especially a
poor/higher resistance interconnection), it may fail from the additional
heating and vibrational stress. However, ANY cap, if pushed far enough,
will fail. High break rates (>600 BPS), coupled with high TC primary
currents (i.e., relatively low primary L) are a recipe for cap failure.
Safe coilin' to you, Ed!

Bert,
What do you call low? When the C.P. cap failed, I would guess the primary
was tapped at about 80 microheneries. I was running at about 7 kva at 14,400
volts. As I said, the break rate may have been as high as 1,000 bps -
probably just beating the hell out of the cap.
