Two years ago, I brought home an 63 Zenith and a 66 CM in the same day. I saw the CRT in the Zenith had been replaced... i think with a late-70's Sylvania tube... it was dead. The Curtis Mathes (which has the instant on feature) had the original tube and tested just fine. Side note- I've brought home Sylvania round tubes on 3 different occasions... all had 1970's date codes... and they were all no good. I think the big advantage on CRTs that have been replaced is the situation where the replacement was a better tube (regarding design) than the original. For instance, the 21CYP22 in my CTC9 was replaced with a 21FBP22. The FBP should have better brightness and reds than the CYP.

At any rate, the face of the tube looks great. I bet it will wake up if you allow the tube to cook for awhile.

yea it checks out ok except the blue gun is weak and compared it between the sencore tester and the b & k the sencore showed alittle stronger but we will see i guess i should remove the lens & pva stuff while its out .knowing my luck once its all together and useing it a caterack will start to show . ill just brake out the sludge hammer and a couple of chissels and pop that lens right off.

Then leave it alone!!! I wondered if it was an FBP when I saw how reflective the safety glass was on it! Thats why I questioned the CRT lineage.

I'd wipe down the bell of the tube with a damp rag. Dont take a chance getting water between the safety glass and the CRT. The rubber gasket may be stuck from all the years of togetherness. I'd be really careful doing things here. GOOD LUCK!!

Nice Pics of Zenith Roundie
Back to the roundie for a moment...
If the CRT is a Zenith, why is there another small sticker on the bell of the tube that says "Hi-Lite" with the CRT type. I thought Hi-Lite was RCA's brand for new CRT's and Colorama was the RCA brand for rebuilt tubes.  Did Zenith buy CRT's from RCA? Nice JD dozer, BTW...

Come on guys, this set is a total POS. Show some self respect by putting your time into something more worth while like a set that is cosmetically sound that only needs ELECTRONIC repairs. The set will never be what it was again and whatever you do to restore it, it will still have a rusty crappy chassis that had mice in it and a moldy cabinet that was pissed in.
Roundies are still out there, its not like you found the only one thats left and its not a CT-100 or some other rare one of a kind set. Keep the CRT, scrap the rest. Lets get real folks.

I think he's more about enjoying what he is doing and there is NOT anything wrong with that, If he chooses to restore something that may not be worth anything to you, so be it.. Nothings worse then me picking up sets with my bad luck with bad crts, and on top of that, buying replacement from another collector which happened to arrive damaged, and this happened twice in a row, I spent over $400 so far on a Zenith roundie, which I'm still hoping I will get my money from the claim I submitted with Grey Hound.. I'm about ready to toss it, and now I know better to make sure the CRT is good in anything else I find or don't touch it with a 10ft pole..
