Using a power factor correction cap works when the load is a bunch of inductive 
motors.  But it won't really work for the pulse type load from a capacitor input 
filter.

Power meters measure RMS current and RMS voltage. But Watts RMS only equal V rms 
x I rms when the power factor is 1.  For lower power factors you pay for Vrms x 
I rms which is greater than Wrms.

The surplus 50V DC power supplies for LDMOS transistors are always power factor 
corrected.

 From an operating point of view, the PFC type power supplies cause a lot less 
flicker in the lights when operating high power SSB...which could be either good 
or bad depending on what you're going for.
