a xl100 19 inch

I have one of those last 19" delta gun colortrak's from '79. It has a digital keypad with a standard knob power/volume control. It worked when I got it. Then, a resistor opened up on the vertical module. Now, it works until it gets hot. Then, I get a blank raster and a bunch of noise out of the speaker. The CRT was replaced, under warranty, with an RCA Hi-Lite in 1980. When I first got the set, I had to give it a little boost; but, it came back strong.

The set produces a really nice picture, almost as good as the CCII set I have.
Maybe at the start of the new year I can get around to getting some sets tweaked and displayed properly.

I found one of these when I was in high school, set out for the trash at a curbside. We were walking to the town park from school for physics class to demonstrate physics properties with the swings and merry-go-rounds. I picked this set up from the curb and carried it about 1/2 mile to the park! and then began to carry it back. Luckily the lady who took janitorial supplies to the schools in the district drove by and gave me a lift back to the school.
The set worked fine and my parents used it in their bedroom for a long while. I'm sure its still at their house somewhere.

Do the crts ever die on these sets? I have seen them with what looks like a million hours and the crt still tested new.

Those late '70's delta gun RCA tubes tended to not be that great. My family had a '77 19" RCA colortrak that got a new tube in '83. I have a '79 colortrak that got a new tube, under warranty, in '80. And, I've seen many late '70's RCA consoles that had weak and/or shorted CRT's that were too far gone to rejuvenate. The older RCA tubes, up until the mid '70's, seemed to hold up better and would usually take a hit and keep going when they became weak.

your right about those crts.the colortrak and later delta guns seemed to last about as long as those black matrix sylvanias.the best crts were made in the early 70s as far as 25v s were concerned.

On those late '70's RCA's with weak CRT's, I'd try to swap them out with Zenith chromacolor tubes if I had one on hand from a junk set. I rarely ever run into a bad Zenith delta gun tube.

only seen one zenith with a bad crt.it was weak,but still delivered a good picture.the red was a little smeared,but still looked better than most other crts.the zenith in a rca is a great swap.that will really make that set tops.
