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!
