"The people are stupider than Jerry Springer now"
LOL...............AGREE!!!!!!!!!!!!!!!!!!!!!
That isn't exactly entirely true. We've been importing millions of people from low eye cue (my comment will auto-delete with the proper spelling) countries. It's not just our people getting dumber (which they are through differential birthrates), it's the magic dirt fail.
Except springer is clever, he’s the one making massive amounts of money out of the idiots on his tv program.
@@Synthematix It's much more cynical than that. We should have never allowed pedowood to get rid of the censors. All the horrible stuff on TV and in movies started the second the censor boards went away in the 60s.
Many years ago when I was in the television business I worked in the repair shop in the 1970s and early 80s we saw a lot of these sets period as a matter of fact in the early 1980s and in the late 1970s you could find these round tube color sets littered all over the streets of New York City. Here in New York City in the 1970s the late seventies it was very very common to find stuff from the 1950s put out on the sidewalk for garbage collection. I was in high school in the early 70s and loved Electronics. I cannot begin to tell you how much stuff I was able to pick up from the sidewalks that were thrown out for the trash back in those days if I had a warehouse I would be a rich man today by saving it all. But nevertheless I did have some space so I decided to save small table radios I sold some a few years ago and now I believe that I have still have over 1000 table radios. Working in the television repair shop as a helper back in the day was actually very educational and it was fun. I am long since retired now and I wish that the younger generation would take interest in this vintage stuff to keep this hobby alive
I worked on those back in the 70's also and I was sad to leave them behind when the boss lost his building.
But they all had dead picture tubes.
I enjoy this stuff but for the most part tube era stuff was out of circulation when I was a kid except maybe amplifiers and receivers. I had a tube zenith set as a kid well into the mid 90s but tubes were already a special order item by then at the only place I knew to get them, Radio Shack. I think one of the issues with today's rookies is that these sets aren't really useful for much anymore. 16:9 downscaled 4:3 yuck. Maybe okay for watching vintage content if you can find a station that just puts through a 480p/I signal. The only ones around here that do it are showing weather graphics or infomercials. Everything worth watching has moved to at least 720p in my area.
SHAGOO66 WAT A KOOL RCA CTC16 VINTAG ROUNDIE COLOR TELEVISON TEX ME WHEN YOU HAVE THE TIME
SHANGOO66 WHAT A KOOL LOOKING ZENITH TEX ME WHEN YOU HAVE THE TIME
SHANG0066 YOU NO WHAT YOU AR TALKING ABOUT WHEN YOU HAVE THE TIME TEX ME
2:20 Shango has one less neighbor. Someone call a bambulance.
BLamBUblanz
Sounds like Chicago on every Saturday night.
@@shango066 The Blam mobile. You can see the sirens and hear the lights!
@@shango066 I used to work on a lot of these sets back in the 70s and early 80s when I was in HS and then college. I don't think the Zenith has a vertical output transformer issue. What I"m noticing is an AGC/sync separator issue. I've seen the delay line cause this issue and I've also lytics cause this issue in that circuit.I see the stretched scanning lines at the top but usually the vertical outputs work or they don't. I've also seen ceramic 3 legged caps cause issues. Those are so many issues that can fool you on these sets because as you said they are complex. You might even try the AGC tube. There is a 4uf cap bypassing the cathode on the 6BA11. Check that and also check the delay line or whatever feeds into the vertical multiplier.
The latest thing to call them is a Glambulance, and camping is now called Glamping, today’s generation of kids are complete morons.
Of all the TV's, there is nothing more satisfying than opening up a mid sixties Zenith color set. My high hours Zenith was worth pulling apart and scrubbing off the nicotine.
Mine had a cooked quad coil and cooked IF coils which had to be replaced.
I got a tour of Hawkeye in Des Moines in 2004. I am an amateur radio operator. While between jobs, I had almost daily lunches with a retired communication tech with Iowa Highway Patrol. He knew everybody and everybody knew him. One day he took us to Hawkeye. Their primary business at the time was rebuilding CRT’s for airports. It was quite an operation.
Thanks for being interested in tv😀
One thing I've found, over the last few years, since I've added a Beltron to my "stable" of CRT tester-rejuvenators is that if a Beltron cannot bring back a dead Roundie for a while, then it cannot be brought back. The Beltron is my "go to" if a shot tube needs a bump! That beautiful Zenith is worth putting in a new jug, it's been well cared for, looks like, and is about at the end of Zenith's line for roundie color sets. 40 years ago, many of these were still in service.
Yes sir. My grandfather had an old roundie Zenith he bought new. I would go visit him every month or so, we were about 120 miles apart. Watched TV together on that old Zenith till he passed in 1982. Still had good picture and color. And it looked brand new. Unfortunately though I wanted to have it, I hadn't mentioned it yet to my Dad, and they had already donated it to goodwill.
I worked for a couple of Zenith dealers in the late 60's and early 70's. FWIW, I've never had to replace a vertical output transformer. I have replaced a lot of (gasp) electrolytic capacitors in the vertical output circuit though. Axial part mounted sideways toward the front/center of the chassis.
My grandmother had this exact model. I recall watching Winston cigarette commercials on the Flintstones cartoon show on it. I really like Zenith sets. They're very well built.
The CTC16's always seemed to have an open ground connection on the R-Y/B-Y filament connection where it meets the chassis. We routinely jumpered the center of the tube socket ground connection to the chassis to get the filaments running again. The wafer switch tuners in the RCAs were crap.
First thing we do before working on them is to wheel them outdoors and blow off the chassis with an air compressor. Works great for getting rid of the dust on them.
Thank God for Mercury Magnetics being in Chatsworth California USA! They will rewind anything you send them. Like you said, it ain’t cheap, but for unobtanium it’s worth it.
In the early 80's i would find these by the side of the road quite often.
My wife at the time would not let me bring them home, they were too old and ugly with the round tube.
By the time I got rid of that wife there were no more roundies.
I know you hate this but I would just pull the small tubes, they were becoming harder to get.
In the early 80's there were a lot of tube sets to repair. At home I had a nice 26 inch Admiral console that I found. I fixed it by changing the donut on the flyback, it worked fine.
I watch Shango’s videos mostly for the educational value but a big percentage of why I watch is for the commentary on the news of the day. Lmao
I worked on hundreds of these back in the day. The ctc 16 was used by a bunch of manufactures back in the day. Easy set to work on. HV should be 25kv. If brigtness won't go down (and has retrace lines) video output tube could be shorted OO you could have a heater to cathode short in pic tube. Isolation trans would take care of that.
Good input.
Every time Shango touches that TV there is a loud bang even when he says there is no sound from the TV.
40:13 + 45:49 I guess it is hats off to the insulation on that green chinese clip lead. Seeing how it connects to the plate of the horizontal output tube with ~2kVpeak on it and then tightly hugs around the edge of the HV cage, I was sure it would arc through instantly.
Well there seems to be benefits to increasing insulation thickness in an attempt cover up for reduced wire gauge...
2kV isn't really too much for thin cables and thin insulation sleeves. With zero safety and environmental margins, that is.
Those sounds in the background that sound like explosions are just sounds of TV parts prematurely exploding as Shango works on those TV's.
Nice two roundies next to each other! The Zenith is a keeper because yes, the cabinet is in too good a shape to be made into a kitty bed. That RCA though, really nice, your friend is getting a good one. They built these things with some style in the day, not just black rectangular things we have today. I'm still amazed at what your Beltron can do, great piece of equipment. The greens are awesome on the RCA, those roundies were some good tubes. Happy 4th of July! (in mid-September).
The ending of your RUclips video vividly reminded me of working on my parent's Sears/RCA
"rounder" in the mid-late 1960's that had displayed JFK/Dallas images just a few years earlier.
(It was just starting to eat up IF, Sync and Color Demodulation tubes every 18 months or so.)
Whoever says Shango doesn't know what he is talking about, doesn't know what he is talking about.
My Dad had an old black and white 25 inch Zenith Console in the 70's and 80's. It still worked when we replaced it with a color Magnavox in 1989
It might be a good idea you having Herr Röntgen's x-rays detector nearby while playing with h.v. of old tubes ;)
not worse that a cigarrette pack
I picked up a marconi 50s crt today after watching your videos for a few years, I'm finally taking the plunge and having a go. Hope I don't pop any tubes. Thankyou for the inspiration
Love how this man be getting TVs older than my grandma in better condition nearly every day but when I try to get one I only get the old beater that has one remaining knob aside from the power button and a cracked screen protector...
Love these old sets !I'm 52 in new Zealand .I never saw colour tv till late 70s our first one was a vidmatic.always gave trouble !solid state .I love tube items .I never saw roundies here so cool
In 1970, our first color TV was a Zenith roundie. It was expensive, but it had UHF, which was new to us...
Your videos about roundies are absolutely my favourite. Thanks for this afternoon's great entertainment!
I’ve seen that frame linearity/line spacing issue near the top on quite a few TVs I’ve restored. Check for leaky capacitors and out of tolerance resistors where the vertical oscillator meets the output, as there will be something deforming that sawtooth waveform near the start of the vertical scan.
The distant gunfire is perfect mood & ambiance.... talk about production values! ⭐️
Looking inside that set , holy cow ! Wow. Where was that set located in a room and when was it found. Lol. My dad worked for Zenith in Chicago, Il from the 60's till the end. So i have seen them all. I miss when a Tv. & radio was a piece of furniture. Remember when you could bring the tubes in and check them yourself to fix a set?
Thrifty Drug Stores had a tube tester in the corner near the ice cream center.
One of the fireworks caught me off guard, I thought a cap had blown. Cool Video!
Always entertaining. I somehow like the old round sets.
love that you replace the tube and keep it running.
rgds
my parents had a set like this down stairs collecting dust back in the early 90s. The modern tv was upstairs but some nights i would hook up the nes and play super mario bros 3 when i was supossed to be in bed. the rounded corners were a bit frustrating. It also took a min to warm up the tubes.
Always enjoy Shango's videos and the ones about the color roundies are my faves. Even though that high-hour Zenith had a lot wrong with it, they are such special sets, they are worth the challenge of restoration. That particular "N" chassis was Zenith's last roundie, I believe.
Roundies also my favorites
thanks for doing more tv's ! its always great to see the ol tubes glow again ;D
Roundie TV news with Shango commentary- it’s the only way that 5 minutes of news was endurable!
I am always amazed at the diversity and amount of test equipment you have.
He bought it off Alibaba
Right up the sound of that tuner being turned was an immediate sign that something was up as a high hour set. At least it lasted.
I enjoy the diagnosis and repair of these old televisions, but I love the sarcastic analysis of the news broadcasts with the working set at the end of the video. Well done!
The news is so full of sh/t who watches it anymore
@@darrengruber9608 I agree, it doesn't matter which country you come from it's the same propaganda. .
Thanks for the attempted TV repair on the roundie. Dad used to take the set to this dude named Morse (how fitting) I guess his real name was Morris? Anyways this was at a time when room ac's broke at about the same rate as the station wagon, and the zenith. Dad had a nervous breakdown - go figure. Bless. Dennis in Miami, FL
Beautiful old sets
Thanks again for another great vid
You should hear the fireworks in The Netherlands at the 31st of December and the days before. It's like Sarajevo 1995 all day long and they don't use normal fireworks but heavy imported German stuff. Nitrate bombs. It's like dynamite.
They do that in the US, too. With July 4th and New Years’, we have a week (or more) of fireworks every six months.
Ah yes, the vacuum filled transistor saturated colour bulb.
Hello from maybe your only viewer from Philippines! Take care shango066!! I need your videos to get to sleep🇵🇭🙏
Always look forward on your videos love it shango
The Zenith is a nice looking set. Great job on the RCA.
Had a 25" Magnavox color TV from 1985 that lasted until 2004. The flyback literally melted itself apart.
It became intermittent and started making whining noises then died. So I went out and got a flat screen TV
and that lasted 8 years until it had a backlight problem. Happy Fourth of July!?! Fear TV news, it's the only thing
that is considered news still. Never let a disaster go to waste.
Thanks for the video Shango.
That Beltron is amazing!!!
The beltron saved the day love that tester darn old school love it.⚡⚡
Maybe
Would be neat to see an entire video on the Beltron, inside and how it really works.
Great idea!
Nice convergence adjustments... 10/10
When a CRT is as dead as that one, risking using the Beltron to revive it is a no brainer, 'cause you can't make it much worse than it was. Also, there must have been at least two dozen different 21" round color TV tube part numbers that should all be interchangeable with only a socket rewiring (except for the 21AXP22).
that never works for a long time....usually decays very very fast after a revive
The shop I worked at in the 1980's had the Beltron and the B&K tester Shango likes to use. The Beltron did a good job "cleaning" and rejuvenating the CRTs where the B&K would always do nothing. Short term yes, but how many hours would the Zenith see in use these days? I would also blast that weak CRT, spoke too soon here we go :-) GO BELTRON !
@@dstoll7958 the problem is that sometimes the "repair" lasts one hour of usage....you recap the tv because it works ,you refinish the cabinet and waste money and hours and then the picture starts decaying very very fast...i have had that experience couple of times and had to eventually find good tubes....it all depends..for example short neck tubes never take a rejuv well....they produce a great picture after a rejuv but it may last for minutes...also gassy tubes, when they glow purple or blue on the gun, the picture starts getting out of focus an i had onewere the picture got completely negative and the contrast control operated on reverse...all problem with air on the tube.the whites were dark and the blacks wre silver, very very weird symptom, killed my brain cells chasing agc, video amp and other sections and it was the tube, i saw the blue glow and replaed it, bam, fixed..
@@MrHBSoftware Understood, short term fix. However from past experience if the Blue lights flash as they did with this tube results should be pretty darn good. I did have a RCA from the 70's that I blasted and it was watchable for a few years after. Depends on the TUBE.
@@dstoll7958 i guess there are some tube were the cathode surface is large and it may work...i always seem to have good results but they last very very little and result in sudden crt death
Mercury magnetics rewinds transformers for old guitar amps . They might be worth a try.
Yes I love that zenith the CTC 16 you refinished the top I think it aired back in 2008 and it had a gessy 3a3 rectifier tube I always liked that CTC 16 myself
The RCA crackled cataract border would look cool with some multi colored neon paint in it. True retro vision in high def 480 with retrace lines. The good old days from yesteryear. I remember an RCA set just like that and watched original Star Trek on it.
STAR TREK ORIGINAL SERIES
For the first set you can try measuring the horizontal frequency with a scope.It does not have to be connected, it will pick up the signal in the air.
I love seeing these old TV's. I started out in electronics working on these.
I like the comment about people getting stupider than Jerry Springer. Just another symptom of the coming Idiocracy. Great movie!
I can’t find ANY of those vintage TV’s here in SC as well, all gone! Only memories of servicing them years ago!
Your the man for vintage tvs⚡⚡🎛
My next car will be "RESTORING INDICATOR BLUE". Nice color.
shango ignoring the gunshots in the background like a boss
Look at that movie LA Story(1991), starring Steve Martin and Sarah Jessica Parker. There's a scene showing a mild earthquake and no one appears to react.
Another scene: People lined up at the bank ATM and another line of muggers with handguns to take the cash from the people who withdrew the cash.
Hi my name is Dave I like your videos I watch them everyday I'm a retired tech I still have all my equipment and I do a lot of radios and TVs on the side like you do keep up the
work and continue to be safe and may God bless and keep you
Very cool vintage.
It's been always fascinating to watch tube colour tvs since here in Europe color tvs came much later. Also, it is curious that generally european radios had transformers and 6.3v E type heating, and the TVs were live chasis 300ma serial P type tubes.
I love watching your videos! I have this same model Zenith and noticed on yours that the blue wire on the yoke is unplugged and behind a clip. Mine has the two blue wires plugged into the top of the yoke next to the red wire.
Very cool sets always wanted a roundie
We had a zenith television like this when I child. I think it was a little bit newer though. My grandma bought it in the 70’s.
Happy New Year !
Painfully old memories,glad we are now in television.I can't even imagine the future in A/V
I hear some fireworks during one of the TV repairs. 4th of July is over, summer’s over, wait until New Year’s Eve.
It looks like it was made on the 4th of July which was three months ago. I was in Lake George when I saw it twice and it was too short, but not good, I went to Woodstock the next month and I saw it. I made a full video of the full fireworks show on my channel. And I did capture the fireworks from Coney Island which was “Fireworks Friday”, and I posted 10 videos of the actual show and it is on my channel as well. It ran from July 9th, all the way through September 10th, and I used Screen Capture to make a full video via EarthCam.
“ vacuum filled “ that always make me think about the term whenever I hear it xD
Its worth putting another crt in that tv it's a really nice set👍
Super relaxing vintage tv Analysis,Good work Buddy...Building 7 The towers and the People all gone...Surely the structural engineers did not get there numbers that wrong...in my head i still wonder.......
God, where on EARTH do you get these things?! Ive been looking for one of these for years and ive never found a single one and somehow you seem to fine one every other week- I tell ya delaware is utterly devoid of vintage televisions... At this point I'd be willing to pay hundreds for even a non working one of these and ive still never even seen one for sale... Having one of these would be a dream!
I know, right?
Sounds a lot like Switzerland - i can't find almost anything CRT based here, so frustrating.
There’s at least 4 large surplus electronics stores in the city of Los Angeles alone and hundreds more in the greater LA area. The one I go to has pallets of tubes and CRT’s for extremely oddball equipment. Sometimes, you’ll just run into old TV sets and console radios people drop off in hopes of someone using it for parts/restoration instead of ending up in the landfill.
I go there for wire mostly. The lacquered cloth insulated type for old transformer leads.
@@matthewf1979 That really hurts. There is nothing in the state of Arkansas anywhere close to that. They don't even do Hamfests here.
@@JohnnyUmphress it’s all about population. I have to drive 2+ hours to get over there and hadn’t been there for a few months now.
There’s nothing like that by me. Hell, the TV repair shop down the street turned into a lawnmower repair shop overnight.
Shango is in the heart of the beast.
Zenith pinched you RUclips Avatar Shango? Bloody cheeky!
Vacuum filled transistor saturated color bulb
Those sure sound more like shotgun blasts than fireworks!
2:17
Talk about...
*Gun fight background sounds
*"DARK!"*
I love those old Beltron testers. Had one back in the 1970s and really miss it. Can't seem to find another one, been looking for years.
they work great i got one just need to find more crt adaptors for it
The B and K 467 wasn't bad either. The delta guns would fare a bit better than later in line. But the idea was to use the clean balance and not go all out for the highest setting. Only used that on sets where the picture was so soft you hardly see it in a dark room. Always let the customer know that could be the end of the tube though, and many times it was
Could we get a video of you doing maintenance on one of your tube testers? would be interesting to see how they work.
Great idea
CRT testing is my fave!
I just shared this and I explained about the different capacitors the bumblebees the black beauties and I said I learned a lot from this guy and I did learn a lot from you and I explained that you are off of RUclips because of the Black beauty capacitors
Screen voltage was a bit high on the RCA you can see raster lines.
I think, that zenith was the model my family had. It got hit by a power surge from lightning. Blew out all the tubes.
Wow
At one time, these were someones pride & joy.
These tvs are great
I have an extremely high hour 1954 motorola set but the picture tube is a relative new replacement. The set works great but it needed a little TLC.
Multmesc foarte interesante sant tutoriale dvs . sant un pasionat electronist si am placerea sa urmaresc un specialist
You can also watch “My Little Pony: Friendship Is Magic” on an RCA Victor “Roundie” color TV from the 1960’s which is really cool.
I had a CTC-16 with a dead picture tube so I ordered one from Lafayette for $60. I think this was back in the later 70's. So Lafayette took my money and sent some receipts but I never got the picture tube. Then they went out of business. I was sad to have to strip the set of parts and throw the rest away.
I agree with you on the RCA vs Zenith thing, and I also think that RCA made the easiest to read schematics, in my opinion
You may both be correct but I can never give anything RCA more credit than sibling Zenith. RCA bigot here.
El CHASSIS ya esta muy trabajado, eso provoca perdida de algunas frecuencias, por eso la imagen se ve con falta de detalles y palida, es decir con COLOR DEFECTUOSO y con falta de BRILLO y detalles.🤔Buena revisión 👍
Someone got a lot of use out of that Zenith TV and took excellent care of the cabinet. Are the decorative handles at 00:16 a call-back to the console TVs from a prior era? Its CRT deserves one of the special Beltron "Serviced" cards from the kit.
Me too enjoy classic TV set
Me too enjoy classic TV set .
How would you feel watching this building come down from one of the other high-rises across the street? OH MY!
I knew you would give in on rejuvenation, I would have done the same
Mestizos love their fireworks.
Two lovely sets there! Pity if the Frame Transformer has bit the dust on the Zenith. Before you think about getting it rewound, is there something else that you could wire in that may work? You have done this before to great effect....
That rca is nice also great crt in it .
Nice set also
You're like me on the rare occasion I watch the news or any new TV. I cannot stand what we've become, or at least how they represent us and the mindless nonsense they focus on. It irritates the living you know what out of me. So like many, I no longer watch current TV. I watch channels like yours instead!
R/e the fireworks-
Just be glad the LAPD Bomb Squad is not setting them off.
With all the crap that's going on it was nice to see this video. Thumbs up forever bro you have a great day. PS I do love to technology they've always been magical to me
I remember these well. I had several where the degaussing circuit would smoke. I'm not sure what that was all about
