You can always use variacs too. 1156's by powerstat work great

reetings Tyler and all,
...All good advice on ballasts - and PLEASE follow Jim Mora's advice with 
egards to safety - with 12-20 kv present, you become a sufficiently low 
nough impedance for the amp or two of current at that voltage to vaporize 
ou!!!
ANYWAY,
...There's a better way to ballast your pig - a far better way (imho) - The 
referred device is a staple found in many neon sign production plants that 
he neonist calls - rightly so a "choke" or slide choke. This device is a 
imple 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" 
quare and 15"-18" long). This is a brilliant way to both limit current - 
nd allow you to VARY it in a stepless fashion - the other methods (like the 
pool of #12 or #10 wire leaves you no practical way to "adjust" current, 
nd 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 
ell for between $250 $500 depending on kva, etc, You can alos check with 
ocal neon sign shops - and if you can speak with the "glassroom" see if 
hey have a spare bombarder choke.
Holler if I can help - I do have a few floating around at all times

A Hamfest is a good place to get parts.
