Bob and all,
I have been blowing caps left and right and have mutilated my primary in the
process. Last night I cut it down to 2.25 turns so I could run a .84 uf
cap. (My primary is made of insulated #10 AWG and unlike bare tubing, it
makes moving the tap a total pain) It was a large microwave cap rated at
24000 VAC. It didn't last 5 seconds. I have seen variable vacuum caps on
ebay. They are generally rated for high voltages. Having an adjustable cap
seems extremely nice although I would never put one on a TC that isn't
already running smooth. Bob, I would like to see the pics on that design.
