Zenith Model 5119

[Kevin Kuehn]

I fired up my 1964 Zenith for the first time last week since I acquired it last winter. Pictures of it in operation after I replaced the blue and green driver tubes and ran through the gray scale adjustment. The FBP CRT tests strong on all three guns. Set uses a 25LC30 chassis. Oops, I just noticed I didn't have the on/off-volume knob on for the pictures.

Nice set. I have the 1965 version with UHF in the same cabinet, 25MC33 chassis. I probably need to check my color driver tubes because I get green flashes on the screen for about 10 minutes until it warms up.

In your caption you reference a "FBP CRT."
I hope not. Your set requires a 21FJP22 for the safety of its laminated safety glass. The 21FBP22 is for installation in sets which have a separate safety glass in front of the CRT.

No.

It could be an FBP - Zeniths had a conformal safety glass that made it LOOK like an FJP, but it's not. It has a rubber gasket that outgasses and leaks oil over the years. It looks just like an FJP in the cabinet - you can't tell, but it really is an FBP.

Better an oil leaking and gassy gasket than an unsightly cataract, I would say.

I'm pretty confident it's an FBP. I stole this service manual picture off of ebay. The 5119 is listed as having a FBP.

In RCA and Zenith sets, the lower priced sets used non-bonded CRT's.
I, personally like it better that way.

It would certainly be a lot easier for us now days if they were all non bonded. Interesting that some of the real wood RCA cabinets actually had the non bonded.

Here's a safety glass for a Zenith with the FB tube. They are thicker and have that glossy/shiny appearance. The FJ's are thinner, yet bonded with a satin/low gloss look.

Ah...the joys of changing a non-bonded tube like for like, firing it up, then discovering dirt between the CRT and face plate!
Personally, I was glad (no, ecstatic) when the non-bonded types were replaced by the bonded types in the aftermarket supply chain.

Very nice Keven, I now have a Zenith itch to scratch.

I think the thinner glass used on the bonded CRT's is not tempered. The resin was the implosion protection.
When removing the nasty resin from a CRT with a cataract condition and reinstalling with a silicone resin around the diameter, all implosion protection is lost.

That's a scary thought, considering how many FJP's have been modified in that way.

Yep! I'd agree.

And I don't believe any one of us here would get mad at a football game and throw a brick at the set either!!
