The 1975 17" Chromacolor II I've been fiddling with needs a new Thermistor, I assume it's for the degausser, it's about the size of a Dime and it's fallen apart.

Anyone have a specific part number that will work?
I see some nos kits on eBay but am not going to pay $25 for one!

Check out this place. I've been getting most of my stuff from them. They've very helpful, knowledgeable and have a decent stock of NOS parts for Zenith.

You can usually solder them back together.
$25 is highway robbery. they were less than $2. You could try
the common 120ohm cold 63-10710 or workman FR922 IIRC.

I have a typical 120 ohm new degauss thermistor if that would work for you, send me your address and I'll mail it to you free. It's usually coupled with a varistor which is a big black flat round one about the size of a silver dollar. If it's alone by itself it's probably a ptc positive temp coefficient degauss thermister. In that case the 120 ohm one won't work, however the TV should operate without it, it just won't degauss automatically. If it's the 120 ohm one and it opens up usually it melts the big black varistor, that's why there sold as a kit together. I used to change a lot of those when I was in the TV repair business.

Okay, that explains why the $25, it was for the matched pair with the large black Varistor.

The one I have seems to start at about 17 Ohms, heating it on the stove it went up to over 200 Ohms, probably more but the meter was set on 200 and it exceeded that.

A Workman FR1010 starts at 16 ohms but they don't say if it goes up or down with heat or what the load is supposed to be, I would assume it has to go up. It would help if I knew the OEM Zenith number but there's nothing on the old one.

The chassis is a 17EC45 if that helps.

We bought them 10 at a time from Bluefield distributing for 3.50 each. 1992 Zenith price guide shows 4.10 for the dealer net, 8.70 list. Zenith consolidated all of the later (non-tube) thermistors to the 63-10710, a 12 ?? ohm thermistor. There is also an "A" version, IIRC, that came about after Zenith parts went to LG long format. 063-10710A is listed several places on the web, so that may be the new part number.
MAT Electronics, Acme, or Talon, your best bet.

Cheers,

Okay, I went ahead and ordered the 63-10710 from Talon, about $10 with shipping, or twice what I paid for the set but what can you do, gotta have it. :D
