Dug out a '77 19" RCA XL100 (CTC85A)

I dug out this 19" RCA XL100 from '77 that I've had for over a year. I rejuvenated the CRT and then the picture developed intermittent "ghosting". I resoldered the delay line and some other connections as well as replaced a 100 uf cap on the video board. I guess I solved the problem since it don't act up no matter how hard I bang on the chassis. I'm sure this set has high hours since both of the neon dial bulbs are burned out. The picture is not the sharpest and it needs the convergence and purity touched up; but, it's still watchable. This one may wind up at the SA since I'm running out of room and can't keep everything. When I was little, my parents had the colortrak version of this set with the single knob tuner. The CRT crapped out when the set was about 5 years old. My Dad had it changed and the set played well into the '90's. It got so it would give off a loud HV "snap" at random times during operation and that's when we got rid of it. It's been my experience that those late '70's-early '80's RCA delta gun tubes were almost as bad as the mid '90's Zenith tubes.
