New Zenith porthole, finally!
Okay you Zenith "roundie" guys, its time to celebrate. After a year of serious searching I finally found what looks to be a nice, restorable TV locally. Just got it home about an hour ago and am looking it over. Appears to be a 1951 Tennyson model H2445R, chassis 24H21. Has a one larger splotch where the finish is gone on top and one major gouge. Rest of the cabinet looks useable as is. The chassis is dusty. Seems like I recall care need to be taken when removing the chassis. Something I recall someone said about the knobs being removed a certain way? Anyway, I'll have my friend Bob's assistance restoring it and that's a good thing. He helped me make my Predicta work about one year ago. No, I don't really know if the picture tube is good. How should we check it before we spend a lot of time on recapping, re-tubing, etc?
Thanks! SteveCopy of IMG_4222.jpg Copy of IMG_4223.JPG Copy of IMG_4226.jpg Copy of IMG_4227.jpg Copy of IMG_4228.jpg

Sorry
I inserted them into the text and probably should have attached them like normal. Will try again. Doesn't want me to reload the same ones I already have up. Oh well.

Nothing special about the knobs. If you can't pull them off with your fingers,
I would just give the chassis a quick yank, and they'll all be laying inside the pencil box.

Is it a 19" CRT - 19AP4 ?
Here is the Zenith Service Manual - scroll to the bottom: http://www.earlytelevision.org/tv_sc..._diagrams.html I have the "Bryon" 24H21 Chassis porthole TV - no doors but the bezel looks exactly like yours. Looks like your Power Supply is not in the proper position. They are indeed very collectible and nice TVs. Carl

It's a 19in, not sure about the CRT number. Where do you find it? When you say the power supply is not in the right position where should it be?

Look inside your cabinet for a sticker. The CRT number should be there. Here are my websites that shows where the Power Supply should be mounted: http://www.cerant.com/ZenithPorthole...ortholeTV.html http://www.cerant.com/ZenithTV-24H21/index.html Carl

CW, after looking at the pics in your links I see what you're talking about re: the power supply mounting place. The only thing is, on the lower part of my cabinet there is obviously provisions for mounting the power supply because there are two little female inserts. one on each side of the cabinet. Yet there is no evidence anything was ever mounted in that position, there is no wood shelf or evidence of one being mounted there in the past. Also, when I view the mounting for where the power supply is now it appears to be a factory mount just like the main chassis complete with the same type of screws and screen material for venting.

Yes those little knobs inside the pencil box can be a little tough to get off or maybe it's just my set . I don't know if mine were glued on by an owner or they were put on at the factory that way. I ended up leaving a bit of I think two of them on the metal shaft but figured I could just glue them back after the set is restored. The big knobs are easy to get off.
