I have a copy of "NEON SIGNS" by Miller and Fink (bought
from Lindsay Publications, which describes bombarder transformers
as being at least 5 kVa and require EXTERNAL current limiting.
Figure 73, page 171 shows three circuits for limiting and
regulating the current. First uses a series resistor (rheostat),
second uses a tapped autotransformer (this is 1935, variacs were
not around yet as far as I know) which controls the voltage, and
third shows a series inductor with sliding iron core.
