One thing about those "Globar" units - the type you want for the filament string is not the same as the type you want for the degausser. You want an NTC (negative temperature coefficient) type for filament string inrush current control, and you want a PTC (Positive Temperature Coefficient) type for the degausser.
Digi-Key ( www.digikey.com ) has these units under "NTC Thermistors" and "PTC Thermistors." I don't know if Globar is still around, but a lot of companies make them.
