1957 Motorola restore
Newbi here. I recently went to San Antonio TX to pick up this old TV my wife watched as a child and want to restore it, so I have a couple of questions that I hope can be answered. The picture tube has been smashed in the back , I am wondering where I might find another one. I took off the back panel and it says Zenith, so did they put Zenith picture in Motorola televisions? Also I would like to find new or at least better looking knobs for this one. I have posted pics below. Any help would be greatly appreciated. Thank you.

If you post the model number from the TV's back cover, perhaps someone can look it up and tell you exactly which picture tube you need. (There are various types of CRTs, not necessarily interchangeable.)

Finding CRTs is difficult. Unlike most other parts in the set CRTs were normally rebuilt instead of replaced (the last rebuilder has been gone a few years now) so there are not large stocks of replacements around. The reason a Zenith tube is in a Motorola is that the original Moto CRT died and was replaced with a Zenith branded one.....CRT's of most given CRT type ID numbers (especially the common 10", 17", 21", etc. types) were often used in sets by various (sometimes all) makers.....Most CRTs are not specific to a single set or brand (though there are exceptions to that).
All that said if it is a 21" CRT (type# should start in 21 ie. 21ZP4) you are lucky. 21" sets are the most common monochrome TV, and the tubes are relatively common still. You first need to find the type number of your CRT (likely on the tube layout chart inside the set or stamped on the CRT) then check this sites' CRTs for sale page ( http://www.earlytelevision.org/ ), Bob Galanter's site (he is user ohohyodafarted, and his site is linked in his signature), and if those fail post a want ad in the classifieds. To be blunt 1950's 21" monochrome console sets are the most common and least valuable tube TVs around, and if it did not have any sentimental value to you (and you just wanted to restore a 50's TV) most here would advise you to scrap it and find a similar set in better shape. Those sets WITH a good CRT can cost almost as much to restore as they are worth after the resto, and the CRT replacement will likely set you back 1-3 times the set's value.

Thank you for your quick reply's. The model number is faded , but I did measure the screen, and it's a 21 inch. Yes this set has been abused, and except for the sentimental value for my sweetheart I would not have bothered. I do like the look of it and am thinking of painting it to give it a sharp look. Thanks again.

If you take off the back, the picture tube number will be written on some paper
sticker inside the tv, It will be something like 21ZP4, 21NP4, 21ASDP4 or anything else you can imagine... But it will start with 21. Post that number here, someone will be able to tell you if it's a correct number, and if it can be had..... Please don't paint it, you'll end up hating it, find a way to restore the wood, someone here can get you on the right track with that too.... It will take some time to get it working, so be prepared for a little bit of learning, and for it to take some time.... Good luck, and good to have you with us..... Better than being against us anyway.... .

The entire chassis and CRT assembly is removed from the front of the set. The chassis number should be stamped on the back edge of the chassis. TS5****. The tube location diagram should be on the bottom plate.
