Hi all,

    I just finished my new 2.375" coil, it was working very nice. I was
getting over 18" constant streamers and occasional streamers over 22".  I
took a few pictures with my digital camera and maybe ill post em somewhere.
I also noticed a few things about the primary and secondary coil.  When I
had the secondary lowered down so the bottom turn was even with the bottom
turn on the primary, there was a ton of corona around the inside turn of the
primary.  I was getting alot of secondary to primary strikes.  Also streamer
length was way down probably because a bunch of the energy was being used to
ionize the air on the primary coil.  After I raised it above the primary so
that the bottom turn on the secondary was even with the primary streamer
length went way up, no more corona and no primary to secondary strikes.

    After running for about 30 secs every 5 mins for about 2 hours the spark
gap would stop firing and would start humming. Anyone know why this might
happen??? Note the transformer is a 7.5/60 new type with ground fault
protection made by franceformer, cap is a Maxwell pulse cap rated at 35kvdc
-at- 0.03uf, and gap was set at 0.170" Also if any one has any tips or
experiments for my telsa coil they are greatly appreciated!! Thanks!

Sincerely,
Nolan Moore
