Re: [TCML] Filter Choice
Hi Scott,
Yea, it sounds like you need to remount your capaciotors.
However, as Bart and others have already pointed out, you
need to leave the capacitors completely out of the circuit
until you have the gaps' spacing set for the peak voltage
output of your transformer. The capacitor will likely form a
resonance with the transformer and because of this, the
peak voltage can reach far higher than the rated output of
the transformer and can quickly destroy the transformer
and/or the capacitor. Once you have the gap set to the
transformer's peak voltage, then you can add the capacitor
and tank circuit assembly and never touch the gap again, at
least as far as the spacing goes ;^)

"And if you're at all unclear on what it means to properly set the gap,
please ask!"
My spark gap is made of of 8 copper electrodes about 1 mm away fom each
other. My current method here was just to start the gap at at one
electrode,
and then increase the distance one by one until it can't break down the
air
anymore. I understand as you increase the distance, and NST has to pull
more current, so if there is a better way to calibrate it, please let me
know.
I actually had to stop it today because at a certain voltage pull, I think
4
electrodes, there was arcs across the cap bank (as in the caps were
putting
out orange arcs that shorted out nearby ones in the wrong way across the
circuit). I think putting them on a PC board wasn't a good idea :(
Anyway,
I'm going to remount them on a plastic panel and get some better
insulation
there to eliminate that little effect.
