There's been some discussion recently of the need for heavy-duty
power resistors as part of a network to protect neons from HF spikes.
An ordinary light bulb is quite good at high-temperature operation,
and its resistance at incandescent temperature is several times its
cold resistance---a nonlinearity that I'd guess would be quite
suitable for damping unwanted oscillations in our protective RFC-
BPC circuit. Does anybody use bulbs this way and if not why not?
