You found one of my Babies. I worked for Zenith from 1973 till 1994. I was part of the electrical design team that produced that TV. Large B&W TVs sold well in the southern US through the late 70s. That set has a voltage regulating transformer power supply, very premium for the time.

A few things: -You can adjust centering by manipulating the rings with little tabs on the back of the yoke (the blue thing on the neck of the crt) -the horizontal stretch/squish issue is from the horizontal linearity being off. There's often adjustments for that and width (also two for vertical linearity and height) on the back, but it might not be labeled. They often fight each other so you'll have to tediously tweak both width/size and corresponding linearity till you get a good balance. Find the model number (stamped on the chassis) Download the SAMS service data for it. www.samswebsite.com/ -the image collapsing to a bright dot when turning it off is often due to a bad bleeder resistor connected to either the cathode or screen of the picture tube. You can either change the resistor or just crank up the brightness all the way before turning off the set so the crt discharges. (it'll prevent a spot from burning in of the screen). -you often don't have to worry about 'lytics from the 70's on. They seem to have held up better and are much more reliable than the ones from the early 60's and earlier. Unless you're getting humbars in the picture or the image is shrunk I'd leave them in... BTW, if you end up needing to get into the chassis, Zenith was smart enough to have the "$ervice $aver" feature, where simply turning the set on its side and popping off the bottom metal cover gives you access to nearly the entire chassis Hope this helps!

This is definitely a vintage television. Zenith really had high quality components in their televisions. If it was me owning this kind of television I would invest the money to have it fully restored so it could last another 50 years or more. This appears to be either a 21" or a 23" being it has the legs for a minature console set. I'm a collector of old TVs that are solid state or transistor type. I would try to get more sets with vacuum tubes but they are expensive to maintain if you don't have tubes on hand which I don't. I gave all my vacuum tubes away when my last vacuum tube television was beyond repair and had to junk it. This was back in the late 80s. The last vacuum tube television I had in my collection was an RCA Victor New Vista KCS149N. I hope you can find a cover for the picture neck so they'll be less risk of it breaking. I am very surprised that the neck was not broken when you found it on the curb due to the cap missing. Awesome video. :)

I've got a Motorola hybrid b/w from 1969. I carried it home a few blocks when spotting it roadside on my early morning paper delivery route. It just needed a new solid state rectifier diode and a fuse. It wss probably 1985. Used it at home for several years. When I moved away for college I left it with the radio museum I was involved with. 20 years later I got it back. The vertical is shrunk and bounces like yours, but starts at about an inch. It heals completely after a few hours. If I used it daily it would be no trouble. I'm going to rehab it and bring it home soon. Something not quite right with the video circuitry or IF. The high frequency fine detail is poor. Enjoy your TV. I'm going to look at some of your other videos. God Bless

I watched this video again just now and wasn't sure if you had done anything more with this TV, but sometimes the vertical linarety control can cause the image to be off center vertically. Usually what I do is adjust the height to see which part of the picture I can get just to the point of the black disappearing, then adjust the linerity control to see if the bottom or top black space comes back and vice versa with the black going away; then I try to center the spacing of the black so its equal on both top and bottom then re-adjust the height for a centered vertical picture. I do agree with you though that the capacitors in the vertical circuit can cause an uncentered picture if there's no additional controls for adjustment. I will say though that picture is nice and bright with high contrast between the blacks and the whites. That's how I like black and white sets to perform so that everything is visible. Were you able to find a cap for the picture tube neck?

Can't even give it away, now....Cool old Zenith you found, though. My dad was a tv repairman back when I was growing up, in the 1950s and '60s, even when some were still using vacuum tubes! I remember how proud he was when we got one of the first color sets, an RCA Victor with a "round" picture tube, about 1963? A lot of tv shows were still black and white....
