I've had fair results using a CD cap for the "C" in a RCR filter. Although I
did need to remove some of the Al coating to eliminate flash-over to the
leads which were just Al taped to the CD's. Anyway it works in a pinch but
the Poly Carbonate losses would be too high for a tank cap operating at TC
frequencies...

Hi,

CDs have a very thin layer of aluminum vacuum deposited inside them.
However, it is so thin that any real current will vaporize it as shown by
the microwave and top of coil experiments.  I would imagine the 1000+ amp
primary circuit would destroy the layer in the first shot.  Connecting to
the layer with a high current connection would also by very hard.  I can't
see any way to use it as a primary cap...

Cheers,
