Now that's something. I'll bet it gets a lot of bidding from the vintage tv/roundie collectors

Forget flat panels
Who needs 16:9 when you can have pi.
Hopefully someone rescues it. Prolly needs to be recapped and whatever burnt tubes and resistors replaced.

I think there's a brightener on that picture tube. Not a good sign, and I think those tubes are hard to come by.

Wow that is nice, I love mine, it took five months to restore, but I treasure it now and I love to watch my old B&W shows on it...
That's really beautiful, Robert. The round screen is amazing. However, it's the hoopty turntable that's making me salivate...
Beautiful cabinetry--and pretty nice equipment in it.Love Unimatics restored one.and yes the TT is kinda funky.The TV in the sale one would certainly be worth fixing up.
beautiful - but
These old babies have more than one TV-Techician notched on their belts. I wouldn't even dream of trying to fix it unless I knew exactly what I were doing - and even then would be extremely careful.
Definitely condensers, high voltage is out...
If I had the time, I'd buy it...but would only work on it following safety procedures *exactly*.
That turntable is a "Cobra" by the way - one of the first true automatics capable of playing various sizes and even shutting off after the last one.
At least it can use parts from later VMs...

Yes--the HV is dangerous-with some simple precautions it can be worked on.You will have to stay away from the HV connection on the picture tube and the HV rectifier section in the set.I used to work on TV's years ago-tube ones like the old Zenith-those were easier to work on than solid state sets.If you can get the schematics-or Sams Photofacts on the machine-it isn't too difficult.Now I work on very high powered SW broadcast transmitters-the caps in those store LETHAL voltages.Have to use the ground stick on those.Like the TV the transmitters have tubes in them and hard to get parts.We manage to keep 'em running.I did fix a "Cobramatic" TT in another Zenith Hi-Fi-needed an idler tire-the person who owned it liked slot cars--guess what made a good idler wheel for the TT-A racing slick slot car tire!! worked perfectly.Was a later model than the ones shown.The times I did get zapped by the picture tube HV I was thrown across the room-luckly the current there is very low-but voltage high.It could also be compared to getting zapped by a stun gun.The HV and current levels in transmitters I deal with are higher-esp the currents.You won't walk away from those.One xmitter here has one tech under its "belt"Am VERY careful with that box when working in it.Use the ground hook on EVERYTHING in it!!

Panthera.....
Hate to tell you this, but that was one of the most dreadful changers ever made! The cobra changer that you are looking at did not automatically shut off after the last record. By the way, that cobra changer was often referred to as the RUMBLE MATIC!....and are very difficult to service....and when they are running, they're not that great. Zenith finally let VM (and later, Webcor/Webster) make some changers for them. With all of the wonderful research that Zenith had, their record players were never that great. Magnavox always knocked them out of the water when it came to record players. Mark

If you take the time to study up on vintage electronics its perfectly safe to work on these wonderful old TV's. I've restored five of them now and use them to watch my favorite old TV shows on. I studied old tv repair books for a few months first and learned all the safety tricks.
Restoring this took about five months of work but it was so worth it. Here is a time-lapse picture of the progress I made with replacing all 60 capacitors in my blonde porthole Zenith...

Finally An Improvement
As a child, the TV always had the back off, we were constantly taking tubes to the grocery store and testing them there, buying replacements as needed,
The TV took several minutes to warm up. It always rolled and required constant adjustment.
The UHF tuner was always in shades of near tuning and often had a screwdriver putting pressure on the tuner knob to hold it just right.
When a tube and adjustment wouldn't do it, we had to call Harry's TV and wait for the taciturn, cranky man to show up.
The advent of a color TV in our house in 1964 only made it worse. A Curtis Mathes for 1,200.
Today, I can buy a 27in Flat Screen Phillips for 179.00 My current Magnavox was purchased in 94 and it plays daily and perfectly. It tunes itself to perfection. It has never needed a repair. If it did, it would be thrown away and replaced.
It is almost impossible to find anyone who repairs TVs anymore.

I truly lament the decline in quality and performance of most appliances, but the TV of today is a marvel of modern technologies.

Cobra Changers
Idler wheels are available for the early Cobra changers.

I wanted to add that the Cobra Cartridge used in the early cobra changers was great technology for the time. It works as sort of an FM modulator and record wear was quite low, again, for the time.
Also, these early changers have continuously variable speed.
I have one here that I rebuilt and it plays quite well.
