Many folks are using the CL-90 Surge limiter/"thermistor". Its specs are about right for normal radios like we usually work on. You can get a spec sheet at Mouser. They will knock you down a few volts in normal operation but they also add heat in doing so. They get quite hot. Slows down warm up time but not terribly.

I'm fond of the Dale/Xicon chassis mount resistors, mainly because I inherited a good stock of 18/22 ohm ones at a good price Icon_smile Other guys cob in a bucking filament transformer which is a no-heat solution and also works well but presents physical limitations.
