Today's Mystery Guest (RCA CTC-4)

[Phil Nelson]

I haven't done anything besides power it up at reduced voltage and take a few readings while watching out for smoke. After the holiday, I should have time to replace the seleniums and start on all that other good stuff.

Thanks to the generosity of another VK member, I have a 21FJP22A with good emission. It arrived yesterday, in my homebrew CRT box that I shipped to him empty. He popped in the CRT and sent it back, and it arrived here in fine shape.



I haven't tried anything on for size yet, since the cabinet is completely disassembled, but I guess some people would cut a notch out of this retaining ring to avoid fouling the 2nd anode lead on the new CRT.



It may be a while before I get to try out this CRT with the chassis. During our remodel, my workshop is packed into 100 boxes and temporarily piled in our new garage, which doesn't have power yet. Our living quarters are so crammed with overflow that I had to unpack the CRT in our front entry -- and then clear away all the mess before dinner guests arrived.

I previously posted this RCA production line photo to ETF. For those that have not seen them I'm posting them here as well. Phil, perhaps one of these is your CTC-4 "Director".

Wouldn't it be cool if mine was one of those? Wonder what "adjustments" those experts are doing in the publicity photo? Checking to see if the top covers fit?

Good one Phil. The photog probably told them to look busy. Here's another photo of the CTC-4 production line I originally submitted to the ETF site.
