I had never heard of a varactor TV tuner with eight UHF channel slots either, until I read your post. Sylvania must have used a different type of UHF tuner in their '80s CRT TVs than Zenith used, if yours has a 20-position varactor tuner.

It's a '79 actually. I'm guessing it was very soon after that Sylvania went with inline CRTs and infrared remotes, which don't interest me. I don't bother with most 80s sets these days.
