- You've seen the before restoration in the porthole video, and the gutted chassis after I sold the cabinet* in the ETF items for sale video. Now you get to see the resurrection between those 2 points in time...
*I did have it listed cheaply on the vintage TV marketplace facebook groups for 2 weeks before I let it go to someone local who will be putting an LCD in it...If collectors won't buy what has to be sold then someone else will.
I really like the way you present your video. Subbed in the first 20 seconds. I'm getting a little tired of how a lot of youtubers are developing a very fake "accent", or way of speaking with inflections. It drives me to smaller channels such as yours that are just a smart guy doing something for his youtube friends.
This gives me good nostalgic memories of late night TV and VCR tinkering.
HELLO BEAUTIFUL TV , BRAZIL
"I'm gonna go full Shango on this". LOL 1:20.
I have one just like it, that I had to rebuild it from scratch 12 years ago. the man that I bought it from, let it set in his barn for 20 years, and the mice moved into it. the tuner was a solid mass( stuck) due to mice piss/ fecal matter. all the lytic caps would not reform, many of the resistors were out of tolerance, so I did a complete rebuild, including stripping the chassis ,and sanding/ repainting it with silver paint( high voltage cage/ power transformer painted black). many of the wafer tube sockets had to be replaced. on start up, the vertical blocking transformer was bad, the electronics supply house that I deal with had one new one( in the box) left in his inventory. the flyback transformer ,power transformer, r.f/ I.f. aircore transformers were all good, and the C.R.T. tested strong, the deflection yoke turned out good also. it has been on the job for years now with no problems!!!!!!
That's definitely a labor of love there! Reminds me of my old Dumont RA-103 Doghouse (more like mouse house). That thing had a basketball sized mouse nest under chassis and they ate about half the wiring harness. Shango woulda LOVED that set... I ended up finding a second chassis (also with a half eaten harness) that wasn't corroded/didn't stink 1/10th as bad, then made one good harness out of 2 and cleaned up the recapacide that the previous owner did to make it actually work....Then decided the cabinet still stunk too much and sold the whole thing.....Granted I still have my Stromberg Carlson TV-10 table top which is also Dumont RA-103 chassis, but in IMO a much more stylish cabinet, and with the dumont part numbers covered over by S-C numbers.
@@tomcarlson3913 ,I am a big "SHANGO/ RADIOTVPHONONUT" fan ,I often feel their pain, I got into electronics repair in the mid 1970's. I stopped repairing T.V. sets due to parts availability, and no C.R.T. supply, both new or rebuilt. you did a great job getting that set to at least pass a picture on it, needing more work, and the deal breaker with that "BOOSTER" on the C.R.T. tells me that it is tired, what a bummer!!!!. I really like R.C.A. stuff!!!!. I like to see people who take an interest in this "OLD STUFF" it beats the trip to the landfill. I never thought that vacuum tube technology would make a comeback, such as guitar amps, but it has!!!!. we need guys like you that can troubleshoot/track / inject signals, and find where the loss of signal is. now that I am getting old with grey hair, someone has to carry the torch!!!!!
I forgot to give "MR. CAROLSON'S LAB" a big shoutout, he really knows what he is doing. you have to be more than a CAPACITOR changer, and have the "GOLDEN SCREW DRIVER" to work on this stuff!!!!! have a great day------- live long and prosper !!!!!
I too have a bag of junk capacitors I have no idea why I keep. I think it's a thing lol
nice video and thanks for the electronics info,.,.,
I Have that set but it's empty..
If you got it this year and are within driving distance of Waukesha it's possible you have the cabinet I sold. I've still got the electronics from my set except for the CRT which someone else bought.
I... I just got it in April 2022.
That lines up with when I sold it...I listed it on marketplace sometime in April this year and sold it IIRC about 2-3 weeks before the ETF swapmeet the first weekend of may (which is where the CRT sold). The buyer asked for it to be gutted and we met up at a local McDonald's. He said he was buying it for a family member to put a newer TV in...If that's you, it's cool to know where it went, and I hope it's serving your purposes well.
Thank you lol
@@tomcarlson3913 Thought you said in video that you were going to use crt for a Porthole. That would have been nice.
Ok you found that all of the first 5 or 6 issues are capacitors. Then you decide you should adjust the cans before just changing out the rest of the obvious caps that should be bad, WTF!
If it was a keeper set, or someone hired me to repair it, I would normally give it a full recap with NEW capacitors (at least on sets like this from the paper cap era).
It's not either of those...It's a set I bought for parts that I almost didn't even bother to resurrect before reselling...The only reasons I did bother were to make it more marketable to a collector (show that flyback, CRT, and sweep work), and to make content.
This was a $10 set I bought to rob the CRT out of for my Zenith porthole, then dump off on anyone who'd take it (I didn't have the room to keep this)...As I expected the person who did take it wanted just the gutted cabinet...So now the chassis is a parts chassis. It would have been a HUGE waste of my time and parts to recap it beyond what I did given the fate it met.
The empty cabinet sold for $60, a full recap would have cost more than $80...Not worth it on a set that wasn't bought to keep.
Now that all I have left of it is chassis and yoke I'm probably going to pull all the caps I put in back out and eventually strip off and keep all the potentially reusable parts on the chassis, and recycle the chassis.
I just bought a very similar doube-door cabinet at the Habitat-Restore. My doors have separate center-panels on top & bottom. There's a tube label inside the rear side of the upper cabinet. So I've identified it as an RCA. Any way to identify the year or model?
I wanted a decent piece of furniture for books & LP record storage that goes with the antique furniture in my parent's home. 1950's mahogany veneer beats plastic-wood & particle-board any day! So I did pay somewhat more than you did. I wouldn't have gutted an intact set, but someone else previously removed the chassis and speaker.
Usually the tube chart will have the chassis number which should start with "KCS-" or model number such as 6T71. If you have the model number you can search radiomuseum.org to find the year. You can also search the chassis number there to find the year and possibly the model.
Sam's photofacts also would include the chassis, model and approximate year (sam's could be 6 months to 2 years late in covering a new set).
Something to keep in mind is back then and into the end of the console era a big company like RCA would only have 1-3 chassis but dozens of cabinet models...The same chassis would get put in a variety of cabinets to satisfy a national customer base with a wide variety of furniture styles that there had to be cabinets to compliment. If you can find either number you can probably identify the year. With only the chassis number you'll need to find pictures of the different models the chassis was offered in online, and if it's not a common cabinet you may only be able to identify some of the cabinet models it isn't rather than which one it is.

Thank you for the quick reply. Aside from tube numbers, the only number on the label is 'PT 650241C-3'. For the picture tube, it states "FOR REPLACEMENT USE FARNSWORHT 170-AR ONLY".
Below the tube-chart, there is -
"Manufactured and sold under United States patent rights of FARNSWORTH RESEARCH CORPORATION"
"This apparatus uses inventions of United States patents LICENSED BY RADIO CORPORATION OF AMERICA"
".... licensed under the Unired States patent rights of HAZELTINE RESEARCH. INC."
"licensed under U S patents of AMERICAN TELEPHONE & TELEGRAPH CO"
(Please excuse the large caps. That's how the label was printed)
Someone may know further info base on this information, or the picture tube part number.
In any case, I'll try to find out more online. But I'm guessing around 1950.
@@sunbeam8866 Interesting. Based on the CRT number I think your cabinet must be a Farnsworth or Capehart brand (owned by Farnsworth since the late 30's). RCA would never use or recommend using a Farnsworth CRT...The reason Farnsworth was able to buy Capehart was because they won a HUGE patent infringement case against RCA.
I'd try typing in all the tube numbers (or at least the CRT number) into radio museum's search by tube number feature and see what you get.
The reason RCA's patents are on the sticker is RCA owned the patent for the Superheterodyne receiver circuit which every TV and radio receiver newer than ~1932 used (by the mid-30's any non-superheterodyne was considered too obsolete to be marketable). Thus every radio and TV made in the US had to carry an RCA patent license...Until Zenith successfully sued that patent into public domain in the 50's.
Searching that CRT number I'm surprised Farnsworth used their own in-house CRT numbers that late. Proprietary vacuum tube numbering died in the early 30's (except for prototypes and I guess cases where Farnsworth ignored the EIA) and all types were supposed to have industry standard EIA numbers...Which for CRTs were the screen size in inches, 1-2 random letters, and the P number for phosphor type (P1 green, P4 white, P22 color TV, etc), so a 16" monocrome TV CRT would have a number like 16GP4.
@@tomcarlson3913 Well. I haven't tried Radiomuseum yet. But a quick online search revealed no images of postwar Farnsworth televisions - just many items about the man, and his early experimental equipment and prototype sets. I did find Farnsworth televisions were made from 1938 to 1951, and quite a few images of Capeheart sets, including a youTube video of a Capeheart double-door cabinet, similar to mine, with a modern TV installed behind the original Capeheart 'picture-frame'.
Incidentally, I've seen a few Capeheart items over the years, including in person or photos. But the only Capeheart I've owned was a curbside-rescued '80s Asian compact microwave in the early '90s. I did get about ten years service out of that before it died.

Found it! Online, in a 1951 color Capehart television ad, is a picture of my exact cabinet, with the original 'brass-ring' door-pulls -
"CAPEHART-FARNSWORTH CORPORATION, Fort Wayne Indiana - an IT&T Associate.
The Capehart "Virginian". Deeply panelled doors highlight a rich mahogany veneer Chippendale cabinet. Big direct veiw rectangular tube for picture, synchronized with Capehart symphonic tone. Also available in bisque finish."
I guess that's appropriate as I'm in Virginia. I'm glad to have the mahogany! 🙂
I find this very informative. Thanks for the video! By the way, your blue shirt looks like a cross hatch test pattern.
Už sa teším. 👍
I really like these early sets. They aren't much to look at, but that's one of their endearing features. Functional design.
Sorry about your camera! I hope you're having a great time at the Early Television show. Maybe next year or the year after I'll go there.
these fine units were viewed as a piece of furniture, I called them "BALL BUSTERS" because of the weight, I worked on this stuff years ago. color sets were out in the mid 50's, thanks to R.C.A. who developed the technology, and who owned N.B.C. went full color broadcasting( A.B.C/ C.B.S held back). it was a far stretch to get the public to invest in the extra cost of buying a color set. so R.C.A. was stuck with color sets in their warehouses that they could not sell. R.C.A. lobbied congress to pass an act that all shows must be broadcasted in color effective jan. 5 1968 also A.B.C. started out as N.B.C. blue( there was at one time N.B.C. blue/ red, that both were owned and operated by R.C.A. ,and yes at that time there was channel 1 on the T.V. set tuner)
@@gregoryclemen1870 I've got one of these sets. I'll have to try and get at it this year and check it out. After the color sets these feel light and easy to move!
@@johnnytacokleinschmidt515 , I hope that you have a "C.R.T. TESTER" , check to make sure that the "BOOB TUBE" is good before you buy one of these gems. you my have bought a "DUD" set if the C.R.T. is in poor shape, new units are a thing of the past, and so is rebuilt ones also!!!!!. "ROUNDIES" are really hard to find.
@@gregoryclemen1870 Thanks! I have several which work well. My Sencore CR7000 is the best. I use my CR143 most frequently. CRT's especially the glass-metal constructed one are a battle. The sets can display well even if the picture tubes are bad. I'll have to see what I can make happen.
Too bad we can't get them rebuilt anymore at any cost.
@@johnnytacokleinschmidt515 , the rebuilder that I was using "BIT THE DUST"!!!! years ago, you can get by on the B/W/ tubes that are weak, but the color tubes are a different animal, if one gun is weak = game over. that is why I no longer work on T.V. sets that have C.R.T.'s where" the lights are on but no one is home". I still work on radio's ,and record players( you can get the idler wheels rebuilt, at least for now)
