Does anyone know of an RCA parts cross-reference source ? I wanted to find out the specs on some NOS RCA parts. One is a thermistor number 137762, and the other says resistor on the package, but it looks like current limiter. It's black and has the part number 132502.
I was given a box of RCA repair parts years ago. Some of parts are easy to identify and others don't have any markings on them.

IIRC findemkeepem has one. Wont get much from that
just subs & general description. Put up pictures & if they
are common we can ID them.

These are the pictures, Zeno. The cold resistance of the thermistor was about 50 ohms. The package marked resistor has a cold resistance of 60 ohms. The resistance of both parts descends the longer I leave the test probes connected.

The resistor looks like a VDR that was used with the thermistor in the degausing circuit.

Thanks for the lead , I'll look in a few Sam's folders to maybe compare.
The parts were given to me from a former RCA repairman long ago.

This may be a typical thermister/vdr pair for degaussing.
The thermister is marked QTP for quick turnover part.
When looking in Sams keep in mind the 6 digit part ##'s
were assigned in order. Odds are both were used in color TV's.
