there are some on a local CL, what do these have in them?

I have a few Quickfacts, mostly obtained through a closeout from a local distributor. They have summary schematics and some parts info - think of it as a digest of one manufacturers Sams info. My JCPenney one covers the gamut - RCA XL sets, NEC sets, and Admiral sets, all made for JCPenney. The least helpful is the one that spans the Zenith System 3 chassis. Lots of repetitions and useless info. Most helpful is the RCA (both), Wards, and Penney's ones, as they list about 20 chassis each.

Sams also published CounterFacts, an abbreviated parts listing for various sets. They are helpful in finding replacements - flys, transistors, and the like.

Cheers,
