Greetings Tyler and all,

...All good advice on ballasts - and PLEASE follow Jim Mora's advice with 
regards to safety - with 12-20 kv present, you become a sufficiently low 
enough impedance for the amp or two of current at that voltage to vaporize 
you!!!

ANYWAY,

...There's a better way to ballast your pig - a far better way (imho) - The 
preferred device is a staple found in many neon sign production plants that 
the neonist calls - rightly so a "choke" or slide choke. This device is a 
simple variable inductor, with a large coil of wire - usually 3-4 layers of 
#10 - #6 magnet wire  and a moveable core of iron laminations (about 2" - 4" 
square and 15"-18" long). This is a brilliant way to both limit current - 
and allow you to VARY it in a stepless fashion - the other methods (like the 
spool of #12 or #10 wire leaves you no practical way to "adjust" current, 
and the old buzzbox welder is "stepped" as the coin contacts are switched.

I have sold a number of these to various coilers with good results - They 
sell for between $250 $500 depending on kva, etc, You can alos check with 
local neon sign shops - and if you can speak with the "glassroom" see if 
they have a spare bombarder choke.

Holler if I can help - I do have a few floating around at all times
