- I replaced a tube In my Zenith color round TV. Mind you I don’t have any previous knowledge of tube TV’s and this is my first. I intend to use this TV as a learning experiences for a way to further my knowledge in analog technology. Any advice would be appreciated and for those who may get upset at my lack of knowledge and take solace in knowing That you can’t start with knowing, you have to learn, and this is my way I wish to.
I remember old TV's took about a MINUTE to even think about coming on!
Man I love your setup - vintage roundie, records and stereo speakers everywhere.
I do, on a purely freelance basis, what you demonstrated in this video, albeit with patterns on DVD and BluRay. Today it's called display 'calibration', but I think a better term would be alignment, as it is akin to wheel alignment - for your TV! 😉
If you like the vintage stuff because the channel is more for my Twitch videos, you can check out my Instagram @GVComputing
@@timtheenchanter0476 Thanks!
My mothers favorite tv along with RCA
Thanks!
Fantastico!!!
I'm hoping you are aware that these old tube CRT's can and do generate extremely high voltages at the plates and caps, high enough to be deadly. Learning is great and yes, everyone has to start somewhere, but those old TV Repairmen went through highly structured training programs under mentorship of senior technicians, mainly manufacturer specific models. None of them (that survived) just sat down and trained themselves. Please be very careful. Assume the line is hot. Assume the plates are live. Assume the caps are charged. ALWAYS!
I have a degree in electrical engineering and mechatronics. I am very familiar with safety processes. I’ve been repairing vintage tech since I was about 12 and have had many people help me learn. I will be careful.
increible, but true.
It would be wise to replace all paper capacitors in the set. Seems that the electrolytics are fine, but at that age, those are risky, too. You likely won't have a proper stable picture until the paper caps are replaced, and you risk damage since leaky capacitors throw off grid bias.
I would love to but I am having a hard time finding any good guidance on how to do so. If you know of any good sources please let me know.
I believe at this point Zenith was using those orange Spraigh orange caps. This TV looks to be 1966.
@@edp9821 Were they film by then? I've seen maroon Spragues that were film, which, of course, is good quality.

@@td3993 orange gum drops they were called.
I hope this TV has been recapped. An exploding electrolytic is not fun.
It has, I refurbish vintage tech mostly TVs
¿Cómo se llama el aparato donde colocas las cartas de ajuste?
