When did RCA stop making XL 100 sets?

I recall the first time I had to work on my first XL 100 set. It was one of the first solid state RCA's I saw. Never got to work on the CTC-40 series chassis, either.

I replaced a glo-bar resistor on it, and it worked perfectly. Back then, I didnt fill in the model numbers or chassis numbers on repair tags. I started doing this later, when I became an authorized service shop. At one time, I had HUNDREDS of RCA modules in stock.

The mid '80's XL sets had issues with horizontal sweep modules, and pin to module connectors burning up.
