September 1962 Zenith roundie ad

[Electronic M]

1962 Was when their first consumer color chassis 29JC20 came out. I've got one and seen a few, but I can't say I've seen one with the remote option....Can't be many around.

One of my regular customers had one. The remote control chassis was still tube. The 5Y3 went bad and I didn't have one with me, so I used a 5U4, until I could get back. It was chancing it, as the power transformer isn't that large.
The set was probably ten years old at the time and the picture was still excellent, with the original RCA CRT.
I still don't know what the difference was between the 21FKP22 and the 21FJ. The FK was the CRT that was in Zeniths of the era!

I am fairly certain 21FKP22 was a Sylvania-produced tube that was the 21FJP22 alternative. The FK used clear safety glass unlike the tinted glass used by RCA. Both my Zenith roundies have replacement tubes and I was not aware of when Rauland started making OEM tubes for them, so this makes sense.
