Shango, I will NEVER get sick of this amazing experiment you're doing. Please keep it up because it shows us youngsters how reliable these TVs were back in the day.
Love the 'Republic' comment; you exactly right; the founders were really worried about a 'democratic' mob! Oh wait, we already have....... Anyway FYI: I realize this has no relevance to this video, but the thought occurred to me when you were talking about the transistors that were giving problems. You can look up 'Machine-Pin' IC sockets on (pick your favorite supplier) and they (originally mil-spec) are very reliable. But what you can do is to break-out the individual machine-pins from the plastic-carrier, and use them as individual transistor-lead sockets; and are better than all but the most expensive dedicated transistor sockets. I normally abhor any type of sockets for long-term reliability but these really standout. Once the transistor is plugged in, they also provide a nice 'shelf' as a resting place for your meter-probe. I started to routinely use these because of problematic PC-boards that were susceptible to lifted traces. 73...
That sure has had some very interesting failures. Good sleuthing on your part! - And no..I've found this ongoing project rather interesting actually. Keep it going!
Some of those old sets were problematic. That is why they had repairmen such as yourself. God forbid America become a Constitutional Republic the way the founding fathers intended... Thanks Shango.
People complain today about tvs being unreliable, damn these things were pretty bad to be honest, real problem Childs, very unreliable, its had about 5 faults in 18 months
Instructions: preheat circuit to 350 degrees. Insert 1.8k resisto-fromulator, and bake for 30 minutes, turning occasionally. Remove and let cool. Serves 1.
My crazy OTL amplifier design uses 225 Watt wirewound resistors running at 63 Watts. They get too hot to touch even at about 1/4 of rated power. I am making them non inductive by winding a copper coil over them. Got to keep below 212 degrees Centigrade to avoid damaging the magnet wire.
Hello Shango. In one of your past videos you used small variable trimmer caps to determine the capacitance required after removing the bad mica in the if cans. Could you tell me the video it is or go over the procedure again please?
It's a good thing that they don't make em' anymore like the good old days. That TV seems to have the same reliability as the reinteraction of that brand, Packard Bell. Those computers from the 1990's Those were pure crap too.
The thing was made in 1968 with original components so it's no surprise they're failing. Good luck watching even a brand new LCD or OLED TV after sitting for that many years. Maybe, I guess. But probably not much better
I would love to see how a NOS Zenith from the same period does. 7K plus hours on 55year components with just 3 o 4 failures ... IMHO it is actually very good. If a was an enthusiast about sets of this period, I would go for a PB.
My 1953 Zenith AM FM PHONOGRAPH with the Cobramatic turntable, console is now 71 years old. My great uncle bought it new. I inherited in 1994 when he passed. 30 years now, I play alot of records on it and a fair amount of radio. Ive never had any issues with it, sounds great, looks beautiful, all the tubes inside are Zenith except for 1.
Shango has a better supply of parts than most radio TV electronics stores did back in the day! Too many ceramic resistors next to each other did this one in as it was almost touching the one next to it. The new one is at least an inch away now from the other original one which should have been replaced too as it's life is well, on borrowed time as demonstrated at 9:26 in.🚬🔥 Excellent correctly stated political advice noted at the end! You are the best Shango!
That's not his stash of power resistors. That was almost certainly at Torrance Electronics, one of the last old-fashioned electronic parts retailers left here in Los Angeles.
@@auchterawer1150 He never actually said anything about that in his video so I guess I was fooled like many who would also think he has a stockroom of parts on his compound! I believe you as I think he once visited the place on video and went into the back room for an exploration.
@hestheMaster he made the comment that the resistor was $2.50 so I assumed he was at the local electronics store. Sadly all the ones near me are gone now.
Its funny, yes it seems pointless, and sick but you take me back to my childhood and teenage days of color tv. I did fix a few tube ones and my uncle had an RCA ctc 25. They were built to fail and i made money off the customers at the tube checker, working at radio shack 1976 to 78. Thanks
Thanks for that update. Strange behaviour of that resistor for sure. It is not a saftely resistor with inbuilt thermal fuse. And I would assume that a normal wirewound resistor from that era(!!) specced at 15W would dissipate those 15W indefinitely and then some. Even if by way of a temporary short on the 18V rail the resistor dropped a full 145V it would dissipate short of 12W. So going open at a mere 7W is strange even with other heat sources nearby. I think the Nichrome Wire broke at a weak spot or it corroded under the influence of impurities in the quartz sand filling. The latter may actually hint toward a manufacturing problem that could affect resistors of the same brand and age. It may be worthwhile to stock a replacement for that preceeding 470 Ohm /15W. Maybe a quick autopsy of the resistor would give some insight.
I would have just used a calculator to find V squared over R for the power but I'm old school. At least I wouldn't have pulled out a slide rule to do it, not THAT old school!
You have to wonder how much of these failures are related to age. I know this stuff was not as reliable as the later solid state TVs. But this seems excessive. If I recall correctly, this is like the 3rd or 4th service call not including the power strip failure.
Go figure that the tubes were the ones to be the reliable side of the set. Early hybrid tech had it's drawbacks. At this point there was much more tried and proven technology and vacuum tubes that are wearing discrete ICs and transistors
That set is a total lemon! 3 times in a month?? you would be lucky to get out of the house with out having a shotgun pulled on you! Customer's complaint " It's the same thing!" And in a way they would be right. It's the same symptom not the same part, Good luck telling the customer that! I would have bought a new set after the second transistor blew.
Yes, it was common to have to bring your set in for repair, or just as common ypu'd have a repairman come to the house and fix it. They were nowhere near as reliable as today's stuff...
@@brentwegher2014Magazines had ads for TV repair schools. You built your own test equipment and even a Heathkit TV in the Bell & Howell correspondence course. You could make good money in the trade.
For me this has been very interesting to see how use and age affects components. I wonder if something else is going on to cause that resistor to get so hot.
7616 hours is quite impressive. Let's say you use the set for one hour per day - that's 21 years! And the TV is still going strong. Let's assume the set has another 10 years in her (3808 hours). 30 years in total would mean this could very well have been a lifetime buy for someone in 1968. Not bad at all.
10 hours per day seems excessive. I think a more typical use pattern would be an hour in the am and maybe 4 at night. A lot of women had another TV in the kitchen they watched soaps on.
Not sick of that set shango.. always enjoy your videos.
Same deal here , keep it up Shango !!!
Love the content!
Nice!
Love the content! i 3rd that notion God bless

Shango on a Sunday is like finding Sunday cartoons playing back in the 1970’s! Yea Shango!
“…and to the REPUBLIC, for which it stands.”
PSA!!! Don't forget to flush your schiff after using the toilet!
That civics lesson... priceless!! I learn much more about politics and civility bahaviour here, than all those wasted years in screwal.
The sarcastic political comment at the end… 😆
if all repairs where so simple, life would be good but it would be boring for the channel. Still nice to see.
I'm not getting sick of that TV I want that TV.

Sunday Shango - Yey!
Agreed!

Uh, no. It’ll become a dictatorship. Trump said so. I say, “Nyet!” I’d say something else, but it would probably be de-monetized. 🤣😆
I think the test of the Packard Bell set is cool!
I am following it. Cheers! 🍻
That resistor was baked. LOL.
Baked…. BAKED!
Shango066 on Sunday is always a super surprise to wake up to.🎉
Some of those old sets were problematic. That is why they had repairmen such as yourself. God forbid America become a Constitutional Republic the way the founding fathers intended... Thanks Shango.
Republic is OK, but is Trumpistan republic?
At 7600 hours, that set actually has performed quite well. Fun experiment!
Nice Sunday Coffee break with my favorite Shango program Love this channel
No Mustie1 this morning, but we got a Shango! Nice!
I thought I was the only person who noticed that.
Make that three of us! Ha!@@jgarner420
I just hope all is well with him.@@jgarner420
Packard Bell........ Classic TV's... then onto building the world's worst PC Computers.
A vedio from shango made our day awesome
Thanks!
Only Democratic or Only Republic. Disappointing, no options for Peoples Democratic Republic...

Ancient parts, though.
@@mikafoxx2717 Which is what would have been in the tv from new, still unreliable I'm sure shango would agree, old electronics weren't the best
I wonder if it would perform differently if it were ran fewer hours per day but for more days?
Instructions: preheat circuit to 350 degrees. Insert 1.8k resisto-fromulator, and bake for 30 minutes, turning occasionally. Remove and let cool. Serves 1.
transistors failed wow........is this because the transistors are just coming out in curcuitry in 1968 or bad design tv?
my brother i love the hack ANYTHING to avoid pulling the chas.
9:36 Doc Brown - "No wonder this circuit failed. It says 'Made in Japan'..."

Yummm Silicone based goo dripping & corroding my chassis. Yeay Zenith picture tubes !
The reading is 374 kWh
kWh stands for kilowatt-hours.
Kilowatt and kilowatt-hour are two different things.
Kilowatt is a rate, kWh is an amount.
Love these updates. Interesting to see what parts fail in a new old stock set. The parts are new and low hour, but are year wise over 50 years old
Curious to know, now long the set would have ran. Back in its day, before it would have had issues.
Maybe the aging filter caps are loading down the power resistor?
Hello Shango. In one of your past videos you used small variable trimmer caps to determine the capacitance required after removing the bad mica in the if cans. Could you tell me the video it is or go over the procedure again please?
Not sick of it at all, I look forward to the content and the commentary.
Democracy is still the best choice. A republic without it isn't good for us, the working class.
Are the amount of failures that this TV has seen typical of a new set back in the 60's or are some of these failures more age-related?
Do an Elvis special on this thing and smell the freedom of a Chinese made LCD as a permanent replacement.
Permanent replacement? Chinese goods are like Taco Bell. You only rent them.
Chinko sprinkler tv?
Chinese goods are like Taco Bell. You only rent them.
TV repair shops made big money from sets like these back in the day.
We are a constitutional Republic.!!😉
nope not tired of these videos!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

That was an interesting short video. Thanks.
i will never get sick of your projects
You can always rely on this TV for new content .
Love this set, it's been a great experiment.
Nice to see the update. 7600 hours is a lot.

I mean the parts are well over a half century old now. So not all that would've happened from new.
Oohh... an extra helping of Shango sauce this weekend! Nice.
When these TV sets were brand new, did they have similar issues??
Yes, it was common to have to bring your set in for repair, or just as common ypu'd have a repairman come to the house and fix it.
They were nowhere near as reliable as today's stuff...
Different brands had different levels of reliability.
In the 1960s we has a TV repairman make a house call about once a year or two.

11:40 unfortunately i dont think enough people know the differences.
That's all well and good but let's see you assemble and Interocitor.
Really bad weather in socal...who knew....please do blather on...😊

Sunday shango fix it 😂
it is one year older than me. I like it
Multipurpose american equipment allows you to watch and listen to propaganda and warms up LA's winter nights.
Never worked with vacuum tubes , i find them fascinating , and no , we are not sick of that set .... keep it up Shango !!! Thank YOU !!!
I never worked with transistors. I'm old school vacuum tubes all the way!
I should add that I was born in 1912 so I am pretty "old school".
Good find and fixed again!
wow
I wonder why that resistor was running so hot. Very odd.
I would check for excessive current draw.
Raining outside here in alsace françe , Shango Time ! Nice
