Shango066, the man who has never found anything he couldn't criticize. Love it.

Wow, this was actually my television set. I bought it in 1975 when I was in college. I marked the date on all my equipment. Note the Dymo label on front. I owned it for over 35 years and sold it on Ebay about 2010. I bought it new. I think I paid $350.00 for it new which was a lot for a 22 year old young man back then. It had very little time on it over the years. The case was made of wood with a vinyl cover over it. It was a great set. I wanted to work in Broadcast TV. Back then to get any experience in broadcast television you had to work for a company that would hire you to get experience a studio or editing company. No luck for me to I started to buy TV equipment, video tape machines and cameras. In 1975 there really were not any VCRs, TV cameras or other consumer products at the time. I had a Cartrivision video tape cassette machine at the time and a 3/4 inch Telemation cassette machine. I also had an old Dage black and white tube industrial camera. I learned a lot and ended up working at NBC Burbank Engineering Dept for over 35 years. When I sold it it had some color convergence issues. The pots were bad that adjusted the RGB guns. The CRT should have many years left on it since I only used it for college projects in editing tape over the years. I sold it with a schematic. Hope the owner still has it. Thanks shano for fixing the set. I never would have found that diode problem. It would come and go. Always thought it was the pot. Thanks again for bringing back great memories of my youth.

Here’s the story behind Lifetime tubes per a friend of mine who was a Radio Shack manager. The Lifetime tubes were rejects and over runs. Sometime in the early 80s, RS dropped the Lifetime warranty as they were losing money on them and renamed them Long Life tubes. The last batch made in the 90s had a blue etch. They were total garbage as stated and from personal experience. Other brands of garbage from my experience are Lindal, ITT Raytheon from the 60s onwards Channel Master and Sonotone. I stick with RCA, Sylvania,GE, Tung Sol(USA), Westinghouse, CBS, and USA made Raytheon tubes and rarely have a problem.

I love watching shango watch TV. Reminds me of my grandpa that would comment on everything that happened.

28:31 I never get tired of that overhead view of the glowing tubes. Those who have never experienced that in person will never know the searing, breathtaking, overwhelming heat that tube TVs give off back there.

I think you'll find the sudden current drop during the 'capacitor reforming' was actually the degaussing thermistor warming up. Something to keep in mind when using a series light bulb when testing colour sets.

It is truly a beautiful audio/video appliance, and it is equally ironic that the current programming is so vapid and devoid of any redeeming qualities. Beautiful diagnosis and analysis... thank you, as always...

Another one with a plot twist, nice. Not jumping conclusions saves you money and frustration, shango is proving this over and over again. I recall these slider pots seemed to have a universal point of failure with contacts breaking off the plastic sled, unless the handle broke off first, that is.

Oh, man, I thought I'd just look in on this. & I'm going on how many mins now? It's been a long time since I've seen the insides of the back of a tv! My dad used to do most of the repair work on our old b&w console tvs from RCA until they went completely solid state. He worked there so he got a discount on all company merch, including all the tubes. I still have 2 1950's models I inherited, one that had picture & the other had sound. 😁 Had to laugh when you were enthusing "It just popped in!". That's one of the deals abt the old tv repairs I recall. Sometimes it worked like wizzardry - like there was no reason at all for sudden responses. My dad would meet a time like that by standing back a step or 2 & just resting his hands on his hips in wonder. I loved it. That's what encouraged me to start messing around w/electronic stuff. 😄

What a neat set... It brings some 80's space management maturity and sturdyness but with quite a lot of tubes.

In about 1991, I bought a Realistic "long life" tube that came in a blue box and had the number hand-written on the box. The tube was a dud, right out of the box. I got my money back and never bought another Radio Shack tube. As far as the video connectors on this set, my elementary school had 23" commercial-grade tube-type RCA color sets (CTC39 chassis, IIRC) and they had those types of connectors on them. They were mostly connected to Sony U-Matic tape machines and in about '87, they got a couple of VHS machines. After elementary school, I never saw another U-Matic machine in use at the school and the TVs were newer solid state Zenith sets. The only exception was one of the tube-type RCA's in my high school biology class and the one time I saw it on, it needed major help. I tried to get them to give it to me or sell it to me, but you know how schools are about stuff such as that. Even the tube RCA sets in elementary school were flaky and it usually took some fiddling to get them to look right.

Radio Shack sold lifetime and long life tubes. The long life were more common after the lifetime tubes went away. I used to buy the lifetime ones and I don't remember ever having one die. They had gold plated pins to make them supposedly get a better long life connection to the sockets. We had a Radio Shack very close to where I lived and they had the tube testor on the wall. One of my buddies got it when they finally stopped selling tubes directly in the shop. I was given a really nice suitcase one from a TV shop I used to get the TVs the customers decided not to fix. Another shop gave me a beat Beltron crt rejuvenator later as well and that really helped up the TVs I could get fixed and looking good again.

Panasonic sure made great products Thanks for this video shango066 !!

By looking at the old Panasonic insignia, I'd say this set came off the assembly line in 1973-74, just before Matsushita went to the new Panasonic block logo -- right around the time of the first Energy Crisis/Arab Oil Embargo.

Love the channel Shango, I come here for your commentary , the repairing is just a bonus! Keep up the good work!

I used to work on special assignment to do Inventory of Corp. Propaganda department back in 1989. I remember I saw this type of professional set including video camera and tapes set in NTSC/PALAM for 110v 50/60 cycles for activity recording and cable similar to this set. It is very expensive back then . This particular set could cost over than thousands dollars back then that not including camera and recording set that could added up to several thousands dollars back then.

Just saw the thumbnail and have to comment on how good looking that TV is. I gotta go somewhere now, I'll get back to the vid later.

What was interesting was how you placed that diode in the sun and it went open, then freezed it and it changed voltage. Cool tv and how it has a connection for an early VTR machine.

PL-259 was THE defacto broadcast industry composite video connector until the BNC started displacing it in the mid-70's onward. I had piece of 50's RCA TV broadcast gear with it. I have a 15GP22 based Tel-instrument monitor, RCA TM-21, 3 different EIAJ RTR-VTRs and a Sony VO-1600 (the first U-matic deck) with those PL-259 connectors for composite video. I wish I could find an early 70's Sony or Panasonic color VTR monitor to go with my EIAJ and U-Matic VTRs. That multi-pin VTR connector fed audio and video in and out between the TV and VTR eliminating the need to connect 4 PL-259 and 1/4" phone jack audio cables between the two. The cables themselves aren't common and are worth a lot of money (apparently they were used on some Star Wars film prop that everyone wants to recreate accurately for themselves).

Wow that set still produces some great color !

Beautiful set and diagnostics. Have to agree about the diminishing returns statement and a complete recap.....but it'd have to be a labor of love doing it.

I wonder if Bob Crane used a device like this to view his home movies.....

Fantastic fault finding . You seem to know almost by instinct what the problem is . Love watching you work . Lovely TV . I bet you keep that one . Best wishes from the UK ...

Allways a treat i watch all your videos to the end. Its even better watching them on my CTC117T.

Those slide controls always seemed to be much more problematic than traditional rotary pots. They were very popular for a while and you used to see them on everything. I used to have an old Altec 714 stereo receiver that had them for volume,balance,bass and treble. A couple were touchy even after cleaning.

Hello from Greece, i like that vintage beauties are back to life.

Wow what a great set! A lot of unusual features it has. Love the old Panasonic logo. Great video. Thanks!

At the start it looked almost like a toy. I think the Idea behind the small tube is that you won't see the low resolution as much as the first recorders for home use had a soft low res picture. Good catch of that diode, intermittent things like that can fool you for a while.

Absolute beauty of a set! Wish I had it in my home.

Those VTR video connectors were the standard on all VTR machines and quite a lot of VCR's in the 70's and 80's.

That poor old TV... it must live through those terrible shopping television programs from today... I love how reliable that old stuff is - it practically just works - minus one Diode...

Another cool TV and diagnosis! All my sets were 4.5 to 12 inch and B&W. Seem to get the sharpest picture on those. Bonus is they also worked on a 12V battery.

Cool little set

I remember in the 60's/70's in England and the channels selectors were a wider band (not sure of the right name) in certain weather conditions we were able to hear french television channels.

what a beatiful unit , thank you for sharing another great video :)

Hi Shango0. That's a cool set. I own a little Panasonic tv set. Still works pretty good. Has always All my very best.

I am always impressed when you begin the attack in one area, only to find the real spot is a half inch away!

Oh, man, I thought I'd just look in on this. & I'm going on how many mins now? It's been a long time since I've seen the insides of the back of a tv! My dad used to do most of the repair work on our old b&w console tvs from RCA until they went completely solid state. He worked there so he got a discount on all company merch, including all the tubes. I still have 2 1950's models I inherited, one that had picture & the other had sound. 😁

Nice looking TV!

Ahh the old 8 pin EIAJ VTR connector. I remember having a National (Panasonic) TV in one of my classrooms in primary school here in Australia. It was a later solid state unit, had the same style inputs and outputs on the side of the cabinet including the 8 pin connector. Always thought the PL259 jacks were odd for video. It explains why many of the AV cable and adaptor multi packs back in the day came with PL259 to BNC or RCA connectors. I can't remember if it had 1/4" audio connectors like yours or if it possibly had RCA connectors. It had a pair of inputs and outputs and the 8 pin, and a TV/VTR switch I think.

That commercial grade Sony and Panasonic stuff from the 70s-80s were beauties of engineering

😊 nice restoration job dude for that old TV for great thanks I really enjoyed the video🎉

Great video. I dabble with TV, I'm a ham radio operator & we just cannot help it. About your old analog system there in USA NTSC. We call it never the same color as compared to our PAL system here in Britain we always thought NTSC color was over the top. I had a multistandard TV & a 1.5-meter dish motorized. That TV was great JVC did PAL, SECAM 4.43 & 5.58 color systems I received NTSC transmissions too on it & I did think the color was over the top,

That is super super cool. Awesome TV business 👍

Esta LIMPIESITA para ser una TV de VALVULAS electrónicas, estas si son ABUELAS TVs pura CALIDAD de la buena, tu si le sabes Jordan buen trabajo GOOD WORK 🙂🙂

I like the look of this Set, it does look New as well.

It's a beautiful set!

Gotta comment early and say that is a COOL set!

Built-in composite input? Truly a "gamers-choice" TV! 😄

1st class video to watch thank you take care kind regards from me kenneth

Interesting set!

PL-259 connectors were used on all broadcast VTRs since they were invented. They were changed to BNC connectors on the 1" machines in the 80s I have been in the broadcast industry as a video tape operator then later as video tape editor since 1960. Now I restore these 2 " machines

Would be cool if the guy that put in the isolation transformer saw this video and got in touch with Shango.Be a good chat for both of them.

My Realistic tube experience. I have used many Realistic Lifetime matched pairs in audio equipment repair and restoration back in the day. Some of that equipment is still in use today. With any audio output tube driven hard they are pretty much toast after 5000 hours. When attempting to get replacements for the Lifetime tubes I was given Longlife tubes that were overrated. Ie 7189A (EL84M is close) with 6BQ5/EL84(s) that amp lit up like a Christmas tree! I went round and round with Radioshack they never did replace them with the correct ones. The 6GH8As' were replaced with 6U8s'. Try to get a stable chroma oscillator in an RCA TV with that. The gold clad pins were cool too. Worked great in worn tube sockets although the socket would have to be replaced once a regular tube was to be used.

A Wonderfully obscure set.

Look at that thing! It's amazing.

Great fix, no one ever suspects the diodes!

Wow! Awesome TV!

LOL that TV was a Turd when I had it on my bench in 1983.

26:34 - Chuck Norris doesn't eat honey. He chews on bees.

Of all TV's in all the shango066 videos I have watched so far, this my favourite It could be used even for retro gaming in my opinion and it isn't that esthetically old The only problem I see is that the picture tube is a little small, but it has a AV input and output

26:35 Showing Chuck Norris just put that TV in perfect calibration and extended its life 5x

WOW - That's a beautiful thing!

didn't try the composite input! thanks for the nice video, was cool to find that bad diode

I had one of those sets without the transformer and modifications, Nice littlt set!

Very good overall convergence, but in fairness, small screen CRTs usually converged much better than their big screen brothers. Great diagnostics and fix.

Nice score I wish I could find one of these

“Baked” make my day …

It's a super tv, natural colors from vacuum tubes!

I have the little stand alone Panasonic color tv version of this set. Same tv chassis. My set looks identical if the left hand side with the VTR stuff was cut off, makes a nice color picture. My set originally had no fine tuning, was just gummed up with old grease. My on-off power switch is bad, so it's bypassed.

Nice TV! Technically totally reminds me of the Hitachi TV I have. This one also has problems with convergence maybe I need to look for these diodes as well.

A tube set with composite video input! That is a rare bird indeed!

Very unique tv still beautiful 📺

Nice Job and I have had diodes flake on me too !

Leak-O-Matic, love it!

Mas que tv linda!Nunca vi um exemplar desse no Brasil.

These sets were often coupled with the Panasonic color EIAJ 1/2" open reel videos tape decks in the 70s, as by the 8 pin connector on the back - we had them in school.

thats a really great looking TV, I love the design aesthetic on the old panasonic TVs and radios, like that one 2" (I think) CRT portable they used to sell, with the magnifying attachment that turned it into a slightly larger lesser quality image. Always wanted to get one and see if it would be possible to mod it for composite.

大変興味があります！😊修理世界一でしょう。

I love the round corners and curved sides. The only CRT television I have left is a mid 80s 13” Sony Trimitron. It’s still beautiful but the squared off tube doesn’t give a vintage vibe.

Shango 066 you have me rolling on the floor with your comments . very funny😃

Perfect for those ad agency offices to capture the competitors crap...so they can study later on how to outcrap them.

PL 259 connectors were quite common for CVBS video in the 60s and early 70s. I have an old sony reel to reel VTR which has them. I also think that the very first top loading VHS recorders made by JVC also have PL 259 connectors for CVBS in/out. Edit: @Free in Jesus was faster than me...

Enjoyed that as usual, thanks. Interesting that you still have proper 4:3 broadcasts. We have 4:3 content shown on UK channels but the broadcasters often forget to send the aspect switching signals or worse: pad the sides to fit a 16:9 display, which results in a horrid squashed pillar-boxed image on a 4:3 set .. unless your converter box happens to have a centre-cutout option.

I'm trying to imagine the mindset of someone going into a showroom, seeing that utter monstrosity, and then thinking - "that's the TV for me!"

Wow very nice I bet that might be the last one left !

Great Work 🙂🇮🇪🍀

Baaaaaaaaked! great vid as always

I have an NEC v t r three-quarter inch deck from that same era and it appears the remote cable jack is similar, Master Control used to hook to that green Jack on the VTR for a b rolls and edits, we never used Panasonic equipment in the studio, the Eng Crews use Panasonic as they were cheaper.

Panasonic made some great TVs.

Greetings: Early in my video career, our facility used many of Panasonitc's triple wide rack mount b&w monitors on editing consoles and singly on each VTR computer control status output. Each and every one had PL-259 to BNC adapters because of BNC ease of use. Not certain, but some early Sony U-matic VERSION may have been similarly equipped. Without use of a power transformer, how was it possible to safely connect grounded video and audio cables to the HOT chassis? Is that scheme practical for use generally with similar standard video chassis or was it a special conversion just to enable the equipment attachments to avoid the dangers existing?

Thanks!

22:35 I think I saw a Horizontal Amplitude adjustment on that board you repaired, that horizontal coil with that white adjuster on it.

you got me laughing at leak o'matic fantastic video thanks

Sony made the best TV's back in the day but Panasonic made the best for the money...that all being said the best TV my family bought was a Montgomery Wards 21" color in 1977...it seemed to work forever without ever needing servicing...

Sony BW TV/ monitors in the 60's and early 70's used PL259 connectors for video in/out.

Here I was thinking that the VTR would be built in to the TV. I like the design of that set.

Awesome

PLEASE can we go back to the 70's so I can have more stuff to repair.
