It should work, you'll just have to find the right voltage to be able
to saturate the core thus stopping all A.C then throw a potentiometer
across it as a voltage divider and you'll be all set. BTW a couple of
days ago I visited a local Neon sign establishment and they had two
bombarder transformers on their work bench. One was about 20 years
old and to control the current it used a large choke (about 15 inches
long X 4 inches in diameter) and to vary the current you pull the
core gradualy out of the windings. The other bombarder was brand
spanking new and guess what, it uses a D.C. controlled saturable
reactor to control the current!
