RCA Parts Cross Reference Source

[EdKozk2]

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.
