No!
PFC capacitance on neon primaries is used to reduce the apparent
RMS amperage draw from the line. In short, PFC on neons allows
you to operate a larger bank of transformers on a circuit with a
fixed amperage capacity.
Example:
You are running four 12kv 30ma neons in parallel with 120 volts
input into the neon primaries. These cores are not power factor
corrected. Your output to the coil is 1440 VA, but you keep
tripping the 15 amp breaker on the 120 volt circuit from the
breaker box. This is where PFC capacitance will correct the input
RMS amps to bring about a closer match to the output VA. The
result is still 1440 VA to the coil, but the 15 amp breaker does
not trip.
