 A
few years ago, I posted an article about the restoration and
installation of my
Alliance Model U-100 Tenna-Rotor. I'm not sure of the exact vintage of my Model
U-100 Tenna-Rotor, but this full-page advertisement from a 1956 issue of Radio-Electronics
magazine presents the Alliance Tenn-Rotor Model U-98, so mine must be sometime after
that. From what I can tell based on the ad, the controller appears to be the same
or very similar. "Model U-98 - fully automatic - incorporates 32 distinct improvements
- eliminates all arcing and consequent picture distortion - points directly, positively,
instantly to target station - 'just set it and forget it!'" It seems they forgot
to make a couple other needed improvements. As I mentioned in my article, the ker-chunk,
ker-chunk of the solenoid stepping through the angle increments is a very strongly
nostalgic memory from the days of yore, back at 114 River Road, in Mayo, Maryland.
