Found a 1979 XL-100 15"

[RobtWB]

Here are 2 more toys I picked up at the same sale. Got them both for their styling only - I certainly don't need any more sets.

The ColorTrak has as good a picture as any I have seen on a CRT set. I had it connected to the satellite, and had an old Emerson vcr playing 007 tapes. It dates to February of 1988. Model FPR 520 WR.
The old Electra Bearcat III scanner is just plain cool - and it has the added bonus of having the local weather channel crystals already installed.

All 3 items totaled less $ 21.00

That's an interesting looking set!

Of course, there isn't a whole lotta life left in that CRT, but you can squeeze a little more out of it.

Memory's a little vague, but didn't summa these (not RCAs necessarily) have a low value resistor like 2.2 ohms or so, in series with the heater, mounted on the socket board? I seem to remember "brightening" a weak CRT by shunting this resistor. Or maybe i wuz dreaming it.

Last June when I set up the DTV converter box on it, it looked like no one had unscrewed the antennas since October 1979.

Probably what needs to be done on mine, the audio is a bit crunchy and distorted sounding.

For some odd reason I remember internal flyback arcing on those. It looked like horizontal circuit problems and after fighting one for days I finally changed the flyback. I remember two resistors always opening in the vertical circuit causing no vertical sweep (220 k?)
Audio problems were generally a touchup of the quad coil. Other than that they played fine.
