- Client had the set working for a year before he lost high voltage. It was a simple fix but he was too busy with projects to dive back into the set. Got it working great. Love these tabletop models. This was a 1949 Admiral 20X136N.

so good to see old tvs like that working, awesome video.
Thank you!
Did a great job in troubleshooting the HV issue, the picture is very good and even if it is not perfectly aligned it adds character to the vintage look of that old set. I imagine it would not be used too much as in an effort to preserve the hard to find tubes.
Thank you for the fun video. It brings back fond memories of my sister and I getting up early on Saturday morning to watch cartoons back in the 1960's. We only had two channels 6 and 12 and we had to play with the rabbit ears to get the best reception whenever we changed channel. Cheers from Canada :-)
Hey thanks so much! I have those memories too but on much more modern CRT sets. Still love getting these sets working again.
this is great,.informative,. thanks, i just found your channel today,.
Thanks so much! Should be uploading more soon!
Excellent video! LOVE vintage television sets!
Damn... It's always a pleasure to see those old bois in working condition.
Excellent video. Thanks for sharing. It is interesting seeing the grid pattern appear on the TV. many years ago, at my previous home in Sydney Australia, I managed to receive a mystery channel 8 displaying that pattern. After making further investigations, I discovered that the signal was being radiated from the television factory down our street. Strangely enough, nothing could be received on a portable TV directly in front of the factory entrance, though the signal could be seen from my home, which was up hill from the factory. The first TV I ever had was a PYE 23" BW TV, which was back in the 1960's.
Great video! I had the “magic mirror “ Admiral that had a great picture for its age. The only bummer is when Dorothy gets to OZ, she’s still only in black & white. Just foolin ya!
Outstanding
Keep on doing the good work.
Thanks so much!
Shango006 would be proud of you, son
I can only hope. He has been such an inspiration to me.
Looks great, Jack! That 12LP4 looks like a new tube. Make sure you get that pesky dual ion trap adjusted properly so you get max brightness and to eliminate any shadows around the perimeter. A misadjusted ion trap can damage the gun if allowed to run with the brightness turned up.
That Admiral looks very similar to my 1950 Philco 50-T1400 which has a much weaker 12LP4.
Hey David! I actually didn’t know a misaligned ion trap could damage a tube. I always make sure I get it to its brightest image before adjusting the brightness. It’s a shame this set isn’t mine. It’s working perfectly. I actually have a Philco 50-T1403 that I’m restoring on the back burner. Might make a video about it after my Zenith Porthole video. I’m glad people enjoy this content. I love this hobby and love making videos about it.
I have a 1950 model Admiral that my dad bought new in 1951. It's a 14 inch rectangular picture. It works when it wants too. I need someone to get it to work.
Nice Tv
That cloth "belt" holding the CRT in is original. I have the floor model with the same chassis and it has the same thing.
Ahh interesting. Thanks for that info. I feel 1940s set really had a trial and error feel to them in certain departments.
Espetacular
Hello michelly Brazil thank 😚😚# l Love you admiral
I like the video. I see your haveing good luck with it . Although I'm not all the way to the end of the video yet. I just came home with a chassis
only about a 3 hr each way so 6 total on the road to pick it up. She advertised it as 1948 but she did picture the chassis # I didn't figure out it
was a 1949 till way to much reserch later . She said 48 I don't know why I thought she was right. Now that I type in 1949 admiral I get more,
info/ I found the schmatic manual, says 1948 to 53 and the service manual for the (1949) 24A125 This will be my first tv to resurec.t The chassis model is 20X1 series 6 the book showa there are other chassis model # that start the same with 20x1 but then the have either one or two more nubers added on I guess they are different cabinets the different added on Numbers are 45.or46 or 47 or 22 or 5 or 6 or 5S or 6S, or 7S or 36 or 1 added on to the alredy existing 1 =11 or 2=12 same with the 5 or 6 makes them look like 15 or 16
this is like watching a kid pull apart a watch :/ back to shango
Just found your channel and it is probably one of the most amazing things I have ever seen. I have been trying to find older televisions, any suggestions? Or will they all be spendy
Thanks so much! Just keep an eye out of Facebook Marketplace, estate sales, antique markets, and you’ll come across them. Just have to look in the right locations. Some people will try to sell for a lot of money depending on the model and some just want them out of their houses. All comes down to chance!
@@televisionforever I thought that might be the case! Beautiful beautiful work you’ve done. Look forward to going through your videos and future videos
The height is too high. You need to match the height according to the bezel.
Interesting. Were these circuits designed specifically to match the bezel on the cabinet it was going into? Cause on a Zenith Porthole, the image is supposed to fill the whole picture tube.
@@televisionforever The Zenith porthole design was a marketing ploy to sell the buyer on the idea that they see far more square inches than a set that has a bezel. TV is 4:3. Take note of some Admiral sets that have a 4:3 bezel such as the Admiral 30C15 S. The width and height needs to be adjusted to fit the bezel so you get the 4:3 picture. A 10BP4 CRT (or 12LP4) when adjusted to fit a 4:3 bezel gives you a 10" (or 12") diagonal picture in 4:3 aspect ratio but with rounded corners. Do you see the selling point of the Zenith "Giant Circle"? The Zenith porthole TV is the equivalent of watching a movie through a porthole.
@@televisionforever As a side note: The set you are working on has the "double D" bezel. You adjust the width to the right and left edges of the bezel and the height to the top and bottom of the bezel.
@@HD7100 Ahh that makes perfect sense. Thank you for that! Very cool. I'll readjust the height and width. Interesting about the Zenith set as well
Very cool video. At about 8:00 in, you say you're not sure whether the knob you're adjusting is either vertical or height. Since the image is being stretched while you adjust, why is that insufficient for determining that you're adjusting height? I would expect vertical to move the whole image up and down without stretching. But I'm not an expert on old TVs and have only adjusted my EGA monitor :D.
Also, what is linearity control?
So the vertical hold and vertical linearity are different controls. Vertical linearity and height look a bit the same when adjusting them. The vertical linearity adjusts the spacing towards the top and the height adjusts the height of both the top and bottom so they need to both be adjusted to get a good look picture. But you’re right, vertical hold locks the picture in place when the picture is rolling up or down.
I just finished restoring an Admiral 12x12 (20Z1 chassis). Wish I had a stronger 12LP4 like you do! Mine is adequate for now. I have excessive horizontal width which is unaffected by the horizontal width control. Other than that, picture, sound, and brightness are fine. I removed capacitor C69 (0.035uf) across the width control. The picture shrunk slightly, but still overflows the screen. High voltage is great (10kv). Horizontal lock is stable. I set the horizontal drive for best horizontal linearity. Horizontal linearity coil seems to do nothing. Focus control works, but must be turned all the way to the left for proper focus. Any advice would be sincerely appreciated.
Oh, and I did a static IF alignment per the instructions in the SAMs. It seemed to work great. Much more picture detail now.
Hello Salom
what model is the pattern generator?
B&K Precision 1211A
Hello Jack, i like you channel...
I likre repair tv`s too....
Where you find the manual service ?
I want study this tecnology before the chips and transistors
Hey man! Thank you! Thanks for reaching out. I got the schematic on earlytelevision.org. I believe if you type in on Google “Admiral 20X136N” it should be the first link to where you can view the technical information.
@@televisionforever Hahaha, look more simple, now i have to study the tubes :-S Jejejejeje
I am trying to get a hold of Jack. Does anyone have contact info for him? trying to get in touch with him. Anyone please help me out thanks, Scotty
