Re: [TCML] Maxed out??

What type of spark gap do you use?  If you weren't using an NST, I'd
strongly suggest going with an asynchronous rotary.  That way you can time
your bangs with the time constant of the tank cap you already have, for
maximum current input from the wall. This works great for MOT and pig
systems, but NST's are a bit frail in async duty, due to the possibility of
irregular bangs, so a larger cap might be the way to go...
At any rate, whenever someone says they are under-performing I always look
at the spark gap first, cap size will help with bad quenching, but a better
cap design with some air cooling is always a cheaper first step, and
necessary for a resized cap anyway.
Just my two cents...
