If you see any BPC CRT sets at the curb you might be able to grab a free thermistor out of one. Da Shacq might carry thermistors or might not, you will have to check.

Most later model sets have a thermistor with a lower resistance at 25 degrees C - something like 12-20 ohms cold. Most tube sets (and indeed his set) have thermistors rated at 120 ohms cold. The Workman FR191 was the universal tube degaussing thermistor for large screen sets. Others, such as Ambassador, MidAmco bargains, and Oneida also made the universals, and even kits (FRTV and others) with the Varistor. RCA's 107191 was the same 120 ohm thermistor - we bought them from the distributor about 20 at a time for about a buck or two.
For BPC sets, you sometimes have a three-lead thermistor. Again, we either used an RCA 143596 (replaced the old 141238), or bought the cheapie Samsung "boxy" three lead. For all other two leaded thermistors for BPC sets, you couldn't beat the price on the LGE (actually Zenith) 063-10710/A thermistors.
I cringe at the folks buying the 24.95 kits off ebay - that guy is a rip-off.......
