[Hallicrafters] S-120 globar

[Robert Nickels]

Has anyone come up with a good substitute (or source) for the globar 
current limiter in the S-120?  The best idea I've seen is to use a 100 
ohm fixed power resistor in series with a modern NTC type in-rush 
limited, but they're mostly designed for loads in the several-amp range 
vs. the 500ma or so required for the S-120, where the old globar had an 
initial resistance of 880 ohms, dropping to 100 as it warmed up.  Thanks.
