You need to be sure that it's the right kind of thermistor. Some drop resistance when they get hot (used in PC power supplies), not what you want here. You want a thermistor that increases resistance when it gets hot. Any BPC set will have one (often enclosed in a plastic squarish box), and you could use its degauss coil as well.

i'll have to order one in a couple weeks. Looks like around $11.

Of note - most BPC sets of late (as WA2ISE correctly pointed out), use a PTC thermistor, usually 15-25 ohms. I had a stock of RCA 141239 thermistors I used or gave away, and they replaced about 90% of the 2 legged kind in 32" and smaller sets. I scavenged the 3 legged TDK/Kamko thermistors from anything I junked, so I had plenty of both kinds at one time. I may still have one or two, but just about any 2-legged thermistor from a BPC set will replace any other. For a 36" set such as this RCA, the inductance/resistance of the coil places a bigger load on the thermistor, so you'll want to have the original type if possible for longer thermistor life. Old sets using the thermistor/varistor combination used an NTC thermistor, and most are replaceable with a Workman FR191, FR291, or FRTV kit. Oneida, Ambassador, and GC Walsco had similar thermistors with similar part numbers (GB191, GBTV, etc.), typically 100 - 150 ohms cold. Just please - don't go buying a 25 dollar thermistor on eBay - what a ripoff. My CTC16 has a new Workman I got off of eBay for 2.99, plus 4 bucks shipping. ......and then I found my stash of thermistors. Cheers,
