21FBP22 on eBay
 

Poor thing was probably ripped out of a gorgeous set :tears:

Yes, it probably was. I thnk the CTC-10 was the last to use a 21FBP22, or possibly the cheap-model 11. I saw this tube, but it's WAY too far. Even if the seller offered shipping, I wouldn't risk it.

I emailed him and asked if there were any other parts from the tv available to sell. Looks like a sulphide tube, based on screen color. Could have been a replacement. The bidding should be interesting.

Looks like it could be a high hour tube looking at the screen shot. I'd want to see a tester on it before any big $'s were spent on it. Zenith had a lot of sets with that tube using a curved safety glass. Looks like it might have a 62 code date.
