Don -
This definitely helps mitigate turn-on surge currents. It's critical to get the 'right size', and
to mount it away from other components, as they DO get hot in operation. 'OH NO, 'wasted' power!'
They also reduce the voltage applied to all components by a small amount, which doesn't hurt with
today's considerably higher line voltages.

I am trying a thermistor from Mouser on my 516F2 power supply for the KWM2A at the suggestion of a
friend. I don't notice the "thump" on the transformer anymore, so it may just be enough of a
delay to help protect switches, transformers, etc. Sure initially looks like cheap insurance!!
I'll post something again after I've really tested this longer term. I will try one on an AC4 also.
