RE: Arc output problems
Do you know if your coil is in tune? Is there a primary tap that produces
better output than taps on either side of it, or are you at the limit of
your primary?
Is there any airflow across your cylinder gaps? It will make a very big
difference.

I was looking for some help on my TC. The last tests I ran I
was only
able to get about 10-11" of spark. Here are its specs with
links to the
pictures. Perhaps the cap was all my problems but maybe im
overlooking
something else.
Secondary - 4.5x20" wound surface on 4" PVC pipe
Primary - 12 turns 1/4" copper refrigerator tube 1/4"
spaceing.
Power supply - unpoted Franceformer 12kv 30ma in mineral oil
Topload - Originally two potlids ,but new toroid has been
built. 17x4"
larger toroid made no output
Original cap used - rolled poly .0089uf ~19kv
Original gap used - 10 section cylinder made from 1x2" hard
copper pipe
0.180 total gap
safety gap - 1/4" each side. Hv-grnd-Hv type across nst HV
terminals.
~I realize .0088uf is not the size for a 12kv 30ma but i was
told the
tranny was 9kv. I found it was 12kv later on.

is a
schematic there that you can click on the parts of ind it
will take you
