...Yow! That's really an interesting mix of design choices..! A tube-hybrid set-- in 1983..! with electronic (varactor) tuning..! *and* Nixie tube channel indicators... *and* it's B&W... Amazing..!
Not only does it seem very surprising that anyone would have still been making tube-hybrid TVs as late at 1983, but the use of Nixies seems especially surprising-- LED readouts would have been a lot cheaper in 1983-- Nixie tubes were pretty expensive, and quickly lost favor in the 1970's after LEDs dramatically came down in price. I don't think any production USA-made TV ever had Nixie tubes, though I do have an old magazine (I think it may have been an issue of
Radio-Electronics) with a picture of an RCA "concept" multi-screen TV that used Nixie-tube indicators for various functions.
