Hi Weazle:

I notice that you have a couple of doorknob caps across your hyperbaric 
gap.  From the perspective of these doorknobs, with every bang of the gap, 
the full charge in the doorknobs is being directly shorted.  While this may 
shunt some HV/HF noise generated by the gap, it's not at all healthy for 
the doorknobs, which are not known for their ability to handle high 
discharge currents.  If the goal is to protect the power transformer, then 
putting some HV resistors (i.e. an R-C filter) between the gap and 
doorknobs would make the caps much happier!

But to switch sides and play the devil's advocate for a moment, I wonder if 
there is any benefit as far as improving quenching or reducing gap 
on-resistance, afforded by having a cap in parallel with the main gap?

Hello Coilers,

My buddy with the digital camera finally got a shot of the new coil,
its temporary MOT power supply, and the TC controller rack.  We have
a lot of tuning and tweaking to do on Big Arnold yet, but right out
of the blocks he produced 40 inch streamers.  Check it out at my
web site listed below.
