The first runs heating the poor allen wrench didn't use a tank

You need RF rated capacitors, or at least very low ESR types. They
are available, but they cost quite a bit more.


II'm pulling 10amps @ 24vdc from my power source during the graphite
heating experiments. The graphite is 1/2" in diameter and 1 1/2" in
length. Takes about 7 seconds to bring it up to orange heat while
running at 150mhz.
I'm assuming you mean 150 KHz.
