This is basically what I did. I believe the material I used was delrin
stock. It is a 5" x 4" square (1/2" thick). One electrode at the top, other
at the bottom. It is incredible the difference this made. I must have had
the "slow drain" going on. I think this was happening on my old gap as
well. The difference now is the gap is louder, crisper, and whiter. I
cannot check the output yet because of a little problem. My capacitor SG
(1/2", loop end design) is popping at very moderate levels, almost
constantly. I powered down and called it a night (close neighbor was home).
I think my problem is 60hz resonance similar to Ed Sondermans a while back.
I've been running without series resistance with my variac ballast. I think
the wood was acting resistively until it finally carbon tracked through.
So, I'm going to try a little R with variac and see what I get.
