Dear Readers,
Anyone ever run a medium or large coil with a glass cap? I'm trying
to figure out how bad the heating problem is at 1KVA and up. I've
only built 3 small coils, all under 500VA. All I've ever used is
glass caps, and I've only experienced one unexplained failure in a
foil & window glass cap on a 380VA coil. A hasty autopsy revealed
glass panes laced with very fine, spider web-like cracks. Might've
been due to thermal effects. My current 450VA coil runs with salt
water bottle caps. I think the water sinks so much heat, I'll never
be able to detect RF heating at such low power input levels.
