Well, I don't think it would be as robust as a PIG because it is not
immersed in oil and I also believe that pigs take real lightning hits at
times and survive. I don't think the neon shops hit their bombarders with as
much nasty stuff as the pole pigs do.
It is a Voltarc-Hyde model SP.BOMB       is this company still in business?
240V 32A
30KV 250 Ma
7.5 kva
The core measures 20x11x5, it has 2 secondary windings that are 10x5 each,
the overall size is 20x14x10.
It has a variable slide choke that is 16x5.5 and weighs a ton.
The bombarder is in open air. It has 2 big windings on it that are wound
over the primary. I had a friend that had a neon business that went under
and I got it from him for $200! I would guess it to weigh a few hundred
pounds.
No, I did not get this off of EBAY, but I think I do recall seeing one just
like it on there. I wonder what it went for?
I am sure if you buy one now new it is a fortune and you could get a pig
cheaper. I always wondered why a neon shop would not rather have a pole pig.
Does anyone think I need to do anything more than put on an over voltage gap
for it? Has anyone ever used a transformer like this with a Tesla coil
before?
Does anyone know if this type of transformer will run fine on 400 hz?

Kevin,

Variable bombarder transformers are very useful and like gold dust. Their
high voltage and lower power rating compared to pigs makes them ideal for TC
use. Yes, running it off 120V will give you a perfect power supply for a TC.
One thing though, a bombarder transformer IS a pig, with a ballast and a
label stuck on it. dont pay extra for a bombarder over a pig unless it has
current limiting or a much higher voltage output than the pig.

Kindest regards,
Jason
