19" Porthole Zenith

[Carmine]

I don't know if I've ever shown any good pics of this one (not that these are very good), but the recent thread about the picture tubes re-kindled my interest.

I WANT IT

The metal back pictured doesn't look like the right one for that set, it looks like it's too small?? Maybe just because of the pic??

I have the same set with the same problem, A bad 19AP4.

What chassis does that set use? 24H20?

I'm wondering what the controls on the rear of the chassis are. From left to right i see focus, AGC, (?), horizontal drive,

anyone have the mystery control?

[Indian Head]

We have one almost exactly like that, except your cabinet looks a bit more deluxe than ours. For instance, there's no lattice grill over our speaker cloth.

The tube is good, but there's a foldover at the top, and other things took priority. Even so, it still is a beautiful design just as furniture.

Ours did come with a Lazy-Bones remote control set-up, although the cord was snipped off. We took the remote motor off the back because it made the set stand too far away from the wall. We kept it, and the handset just in case we wanted to restore it.

That's a nice set Carmine. We'll post a pic of ours in a day or so for comparison.

Thanks John.

Those big porthole Zeniths may look like Washing Machines, but I'd give my eyeteeth for a good workin' one-Maytag jokes 'n' all...

It isn't the correct back for the set, it's just what came with it. Better than nothing I guess.

Hi Carmine could you please help,

I have the same set and model #.
However when I had it shipped the 1B3 rectifier tube socket sitting on top of the little metal cup which in turns sits on top of the doorknob 500mmf/20K cap all came loose and was just lying there when I opened up the flyback cage. Consequently I am not sure just how that rectifier assembly is set up and your rear photo doesn't show enough detail. My question is; from what I can tell in your rear photo it looks like a short wire between the little metal cup just below the tube socket is going off towards flyback? Can you please tell me just what both ends of this wire hooks to it and also if there is some kind of bracket the whole 1B3 assembly sits on? This cap is suppose to ground at the base of the assembly I thought so what is this mystery wire for? My email is [email protected] if could help me with a close up pic of the flyback cage.

Thanks
Stan

I could try to take a better picture of the set, but I suspect that someone with more knowledge of the set than me, will respond first.

I also have this set with a good crt.

Hello guys, were can you buy the sealer to seal the front of the crt face to the metal bell of the tube. I would hate to see my 19ap4 go to air, any clue?
