need help identifying these quasar sets

[radiotvnut]

That knob tuned Quasar is in a cheap particleboard and plastic cabinet and I would be shocked if the CRT isn't weak. The flyback (IIRC, is a TLF14412F) was a high failure part and the chassis was known to have bad solder connections. Don't waste your time or money on it!

The keypad tuned Quasar looks a little older and is a little better TV; but, it's still nothing I'd spend a lot of effort on.

The RCA's were good sets. The main problem they had were loose connections in the tuner/tuner control module.

If you can get that older TV that doesn't work for a good price, get it. The fact is that most vintage TV's that you find are not going to work at 100% and you will have to do some work on them to get them back up to normal condition. The first thing you want to do when you get a vintage TV is check the condition of the picture tube and other vital organs (such as the flyback transformer). If these are good, it will be much easier and cheaper to get the TV back in business.
