I friend just dropped of this set he picked up down in the Champaign/Urbana, IL area. The owner ssid it had been in his family since 1952.
I don't think that's possible though since it has UHF and the inspection tag says Sept, 1953.
It's a 17" set in a black bakelite (or is it plastic ?) cabinet. Rather light since there's no power transformer.
Odd that his dad would get a set with UHF way back then. Did they have UHF in downstate IL back then or could he have picked it up from Chicago ?
It has a TS-410 chassis.
Uh-oh, that doesn't look good

Sure enough - the 17HP4 is dead
That's a shame it was replaced with a Sylvania Silverscreen 85 in 1963.
