My CTC 11

[Kevin Kuehn]

My RCA field service guide states that CTC-11's could have come with one of three types of CRT, including CYP, FBP, or FJP. But there's no elaboration as to rhyme or reason.

I THINK...the first run of them had a CYP...then they went to an FB/JP tube.

I remember seeing that notation!
It must've been the real early production set that used the CYP. I've never seen one.
Tom S. would have to look inside to see if there is a serial number tag on the CRT matching the chassis tag.
Either that, or the CRT is a replacement.
