Thank you so much for this video! I have a 1939 Zenith 9-S-369 shutter dial that a older family friend gave to me when I was in high school (25+ years ago). It never worked, but I've held on to it all these years. My interest in DIY electronics has been re-sparked (no pun intended) recently, and I'm planning to restore it with my son. You have a new subscriber! :)
What a very cool radio! I've never seen a shutter dial before! Michael you are actually who got me started in this hobby a couple of years ago. I bought a Philco 47-1230 and while doing research found your restoration of the same unit. Watching you gave me the encouragement to try my hand at restoration. I lost your sight and luckily I found you again through Larry over at Backtothefuture radios. This looks like an exciting series, and even though it's a couple of years old I'm really looking forward to it. I learned so much from you I'm in the hobby now with my own channel. I learn something new every day and have expanded to watch many channels now, to continue to grow my knowledge and ability. I'm still figuring a lot out as I go, but I love doing it. There is something about bringing something back from rubbish to treasure and hearing an old radio come back to life after so manyyears, that just thrills me. Now I have many of your series ahead to watch! Thank you!
Thank you so much, Graham. It is very good to post again. I'll be slow for some time, but I will try to keep posting. I am very glad that you watch my ramblings, sir. I most especially appreciate your kind comments! Cheers! Michael
Hi. Great vid as always. I have a 9s262 in need of restore so feel free to ramble on as much as you like and if by accident the alignment vidoe ends up taking longer than you imagined then don't worry as it will greatly be received. All the best to you ands your family.
Steven, You probably know that Zenith alignments from that period were all pretty much the same. The only things that changed were the sheer number of trimmers, and the introduction of the Wave Magnet (in 1939, I think). Otherwise, if you follow along with the Zenith that I get into after this one, you'll see that it is pretty straightforward. Thank you for watching and for your kind words. They are very much appreciated. Cheers! Michael
Good to see you, Yea those acoustic units on the back of the speaker not only made the radio sound better in certain room conditions, but they also protected the speaker from the back side as well !! My cat loves to do the same to me too rub my chin, want to crawl up on my shoulder, I like cats too, no I LOVE CATS !!
I cannot recall any time in my life in which a pet cat was not in the picture. They are a part of the landscape around here. Marty goes home to papa (my son) tomorrow, and I'm kinda' bummed. Cheers! Michael
A few possibilities on the noise in the rectifier tube. Might be a bit of glue holding the base on that broke off and is rattling around in the base under the bottle where you can't see it. If so that's nothing to worry about (except that the base might come loose, but a bit of glue will fix that). Also might be a bit of glass that broke off from inside the tube, part of the press assembly that the lead in wires go through. So long as the getter coating is still silver and not milky you're still OK, the tube is under vacuum. The only BAD thing could be if one of the welds that holds the plates to the support rods broke, or if the spring wire holding the filaments under tension broke loose. Newer tubes don't even have the filament spring wire, the filament is held in place by a mica washer on the top of the tube. Key here is a good visual inspection. If you don't see anything that looks like it broke loose, you're probably OK. Those rectifier tubes are big enough inside that you can visually see if they've gone wrong. Finally, put it in the tube tester and tap on the glass while you have the test running. If the short or gas lamps don't flicker, and the meter reading stays constant, your'e OK. If an eye tube is weak, you can get it to work for a little longer by increasing its filament voltage. The easiest way to do that would be to find an old TV picture tube rejuvenator and wire its transformer in series with the eye tube's filament. You'd need to get a new 6 pin plug and socket to change out the CRT one's that came with the rejuvenator, to fit the eye tube. These things increase the filament voltage from 6.3 to about 8 or 9 volts. Another rejuvenation technique is to charge a capacitor up to a few hundred volts and connect it between the cathode of the eye tube and the grid / target of the tube (negative to the cathode). The idea here is to give a big suck of current out of the cathode which is supposed to reshuffle the oxide on the cathode bringing a fresh layer to the surface. Many CRT testers have this function built in, but the idea works on ANY 'valve. It's strong medicine though, and can also destroy the cathode if done too often. However it's worth a shot on an otherwise useless tube.
I think that one of the element supports had broken free on that rectifier. I wound up replacing it. I didn't get a warm 'n fuzzy from it. I have a good source of eye tubes, here in Salt Lake. They're not cheap, but most owners choose to buy them so that they don't have to think about it down the road. I liked your suggestions, though, and I'll pursue them sometime. Thank you for the tips, and thank you for watching. Take care. Michael
It's a sad day tomorrow. My son is coming back to pick up Marty McFly... [: 0(He slept by my head every night that he was here (except when my daughter visited!). I will miss the little vagrant. Thank you so much for watching. I love your comments. Take care, my friend. Michael
I am sad to read that Marty is going home --- his other home. Will miss seeing him, and will take consolation in the Fred Cam! Lov your vids, keep em coming! They are very instructive.
thank you! i just found a 37 zenith boat and trailer chassis.. shes in terrible shape.. broken tubes, mice ate the coils.. i dont think i can restore it, but i want to at least try and bring it to a working condition and build a new box for it if i can.
Glad you found Larry. Someone left the door unlocked and he wondered off, but we have him locked back up. ;) I look forward to your next video. Interesting radio.
I'm glad that Larry followed the bread crumbs leading back to Tennessee! It was fun showing him my favorite stomping ground. It was especially cool that he got to meet R.A. Elco Robert. Thank you for watching. Take care. Michael
Well looky here.. Larry the mountain man his self!! What a nice picture of you two guy's. The shop with all that gear looks good from 5000 miles. But I do want your sweatshirt!!!
I've seen those sweatshirts on both ebay and Amazon, but none would fit me. In order to get one with sleeves long enough they expect me to be as big around as I am tall and they don't come in tent sizes, LOL!
With me, it's like everyone say's go to a big & tall store. I tell them that doesn't work because in order to fit tall you must also be big....I need a big OR tall store, lol. I have shirts that the sleeves do fit me on, but that's only because I could fit another person inside the rest of the shirt with me.
Rod,I've forgotten where I bought the sweat shirt, but I'd bet that I could find one on eBay! I have had it for four years, and it has not faded and has hardly shrunk. And, lo & behold, the tag says "Made in USA"! HHmmmmmm.....Cheers! Michael
That is so cool that y'all got to meet up! From the Western Outpost & The Hills of East Tennessee, hmmm. I'm gonna have to come up with a location for here....I've got it! High atop Poverty Ridge in Canton, Indiana...lol. Both my still camera and my video camera are Sony and I've had them both for close to ten years with no problems so far...they must have been made on a Wednesday, lol. You'll have to show us how to open up those eye tube sockets when you put that cap on. Take care, Gary
OMG! Poverty Ridge! That is too funny. You could call it land of Northern Rebels or Land of Southern Yankees! I think the older stuff that Sony made was fine. But, in their camera and camcorder ranges now, they seem to be opting to make everything as small as possible. Of course, that necessitates that the batteries are miniscule! As always, Gary, thank you for watching and for chiming in! Cheers! Michael
It was great meeting and visiting with you Michael! Lunch was excellent, just too much to choose from and not enuf room to hold it! Lol. R.A. Elco was a great place, and you failed to mention, that because of my VIP status, he even let you go into the catacombs where you had never been before! Lol. And we also got to hook up with Stewart! Lol. Maybe you can share that story on one of ur videos! Lol. Thanks again! Take Care- Larry
I distinctly remember my visits to the supply house in the small city in which I was raised, and the assurance of 'strength in numbers', whereby every area service tech "griped, bitched, and complained" about problems inherent to certain brands of TV's. Even though the guy sitting next to you was essentially your competition, information from their experiences served to help everyone when encountering 'that glitch which you just can't find'. We bailed each other out of complex troubleshooting problems. There were times when one, or two man repair businesses were nearly forced to close due to any number of problems - and the TV repair community would cover their service calls, and do their carry-in's, or other shop work, until that key employee was back on their feet. (the fees were split amicably, I once installed a 25AP22 CRT in exchange for a homemade cherry pie) It was a much kinder, gentler world back then... That couldn't happen now.... You have a precious asset in Ra Elco; seeing the amount of traffic they have is encouraging, we lost so very much by the late 1980's, largely because of throw-away electronics, and the (then) impending failure of USA-based electronics manufacturing. Great that you had Larry as your wing man! It had to be frustrating for him, to have experienced the ambiance of Ra Elco, then realize that there is no local equivalent in his neck of the woods. My best to you, and take care, Tim
Oh, man! I wish I had your experience! I'm freshly senior, but I feel like a dumb kid when I talk radios with folks that actually know a few things, like yourself! I have insisted for many years that I was born about 40 years too late! My favorite car is a '38 Buick Century, My favorite music is by Benny Goodman, and I'd rather watch a Jimmy Stewart or Cary Grant movie any day of the week than watch Brad Pitt or even Harrison Ford! Oh! And the beautiful ladies of the 1930s and '40s. Need I say more? Back to radios..... I am extraordinarily lucky to have a R.A. Elco to go to. I make sure to spend plenty of money there to do my part to help keep Robert and his crew firmly entrenched in the Salt Lake landscape. Thank you, as always, for watching and for your excellent comments and observations. Take care, my friend. Michael
Michael, I don't know if you've viewed any of "DRH4683's" videos, however, the channel's proprietor, Doug H., for well over a decade - has chosen to live in a time period which spans the years from 1952 through 1980 (give or take). His mantra: "I tolerate the present, by living in the past". While still in his early '20s, he constructed a Zenith dealership in his basement, including the obligatory "terraced display" - complete with a vintage 1965 'polyester banner'. A few years ago, he purchased a home which was a 1960's "unadulterated time capsule". Each Christmas season, he decorates the exterior with the GE colored bulbs, those very same bulbs which we grew up with. You'll enjoy these videos immensely: ruclips.net/video/4pGLqWOLhTo/видео.html and ruclips.net/video/q0-FPx7FgRM/видео.html His channel: ruclips.net/user/drh4683 Take care, Tim
Muchas gracias amigo mío. Me alegra que disfrutes los videos. Me divierto haciéndolos. Gracias por mirar, y estoy muy agradecido de que te tomes tu tiempo para comentar. Cuídate. Miguel
Nice to see you back been missing you. Hope everything is good!! Can't you regenerate those Magic Eye tubes? I thought I saw somewhere you could. I was wondering about running a snubber capacitor, after the rectifier tube on the output this I think will help to give you a more beefier power supply and cleaning up the mains. I mean it works great on solid state bridge rectifier on a valve piece of gear, not sure if there is any benefits would be if any? on a valve Bridge rectifier. Considering how much noise today on the mains, it might have a bearing on filtering this out what about trying it and see?
John,Everything is always good, when we wake up on the topside of the grass! I'll have to give your snubber idea some thought, though I'll bet that you have already worked it out! Thank you so much for watching, sir. I always enjoy your comments. Take care. Michael
About those tube sockets, I bet that was for production so that there would be less confusion for assemblers.same thing for pin sockets. Having only the sockets for the circuit you would have less opportunity for a mistake. Maybe put them together faster with less mistakes. Might have offset the cost of the tube sockets.
I think that you might just be right on the money! Zenith built among the best radios of the time, but it also seems that they were very cost-conscious. Marking the tube sockets and having them contain only the terminals needed for the application would not have saved much in parts costs on the sockets themselves, I think. However, as you eluded to, preventing mistakes would have been a tremendous cost savings! Zenith would have been way ahead of their time, if they actually did that. Concepts like "Poka Yoke" (Japanese for "mistake-proofing") and "5S" (another Japanese approach, meaning to keep only what what is needed for the work, where it is needed and eliminate all else) were not developed and made popular in the U.S. until well after the war. Knowing just a little about the history and leadership of pre-war Zenith, I wouldn't be surprised to learn that you are spot-on.
Hello, and thank you for the Zenith 9s262 repair videos. I am repairing one myself, and need the tone and power on/off switches. Any chance you have any for sale? Or a source to obtain these 85 year old items, thanks, keep up your great work,! Bill
I got a kick out of the mosquito crack, too! I am a big, big fan of Zenith shutter dials. I enjoyed doing this radio. Thank you very much for watching and for taking some time to comment! Cheers! Michael
Damn! wish we had a store even close to that , we had one up until 3 years ago and the closed as no one was servicing any equipment and even then it was no way stocked with parts like your store is
We are very lucky here in Salt Lake to have a store like R.A. Elco. They do an awful lot of business with local manufacturers and equipment operators that have older equipment and occasionally need parts. In fact, I think those businesses are a large part of how R.A. Elco is able to stay alive. In any event, I try to buy as much there as I can. Gotta' help 'em stay in business! Take care. Michael
I mentioned in one of your other videos. Look into the Russian eye tubes. They are direct replacement except there octal. You always have to rebuild those sockets anyway why not just swap it.
Hey, Doug! I filed that little gem in my memory banks, too. Now I remember that tape and yeah, we did call it friction tape. This stuff was sticky and unpleasant to mess with. I never use the stuff or it's vinyl cousin! Thank you for watching. I always look forward to your comments, too. Take care, my friend. Michael
I remember taping that stuff to the handlebars of my bicycle. After a while the heat would bleed the adhesive and I'd have sticky hands. Good times, lol.
I would say replace that power rectifier tube, that might even be part of the hum problem, if it is not it will soon fail, most likely filament to plate too and like you said destructively to the rest of the radio and power transformer especially !!
I did. and didn't charge him for it, either. I put in a good NOS unit and kept the rattly one as a demo/curiosity! I finished the set weeks ago. I played it on the bench for a couple of days to make sure that it was good. Or....was it because I love shutter dial sets and I didn't want to give it back...? In any event, the owner was very happy with the set. The day that I told him that it was ready, he reminded me of our plans to set up a Bluetooth aux feed. I had forgotten, but the old Zeniths are easy and are particularly friendly to minor mods like that. His cell phone sounded great coming out of that 80-year-old speaker! Thank you for watching, John. And, as always, thank you for your terrific comments. Take care, my friend. Michael
Good afternoon Mike... I mistakenly made a comment at the beginning of one of your other videos... I will restate my info here.. I have the exact same radio you are working on here. I would like to talk to you about restoring it. I live in Utah and could get it to you without any problem. Can you give me any way to contact you regarding this quest. Thanks, Kay, N7KH
Hello, Kay! Thank you so much for your comments. I'm easy to reach. You can send me an email, if you like, at thattubesound@gmail.com . I will look for a note from you. Cheers! Michael
MAPLIN UK is gone for good, just like the COSSOR radios, That is why I will never trust a SONY, is there a Svetlana version of the ZENITH vacuum tubes that will work in a ZENITH radio.
I have two Sony a6000 and one Sony a6500 mirrorless cameras. They have the same sort of problem with battery life - too stinking short! Not only that, but the stupid things heat up and shut down on overheating protection fault. I think that I'll put the lot of them and all the lenses up for sale. With such miserable battery life, they don't do me much good, spectacular as the image quality might be! Thank you for watching, David. I am very grateful for your comments, too. Take care, my friend. Michael

Hi. Great vid as always. I have a 9s262 in need of restore so feel free to ramble on as much as you like and if by accident the alignment vidoe ends up taking longer than you imagined then don't worry as it will greatly be received. All the best to you ands your family.

If so that's nothing to worry about (except that the base might come loose, but a bit of glue will fix that).

At 13:30 I would add a grommet to where that grid cap wire is passing through the chassis.

Concepts like "Poka Yoke" (Japanese for "mistake-proofing") and "5S" (another Japanese approach, meaning to keep only what what is needed for the work, where it is needed and eliminate all else) were not developed and made popular in the U.S. until well after the war. Knowing just a little about the history and leadership of pre-war Zenith, I wouldn't be surprised to learn that you are spot-on.
Hello, and thank you for the Zenith 9s262 repair videos. I am repairing one myself, and need the tone and power on/off switches. Any chance you have any for sale? Or a source to obtain these 85 year old items, thanks, keep up your great work,! Bill
I am in Oregon.
Great video! I love my 9S262! Your cats are neat too! I've got to ask Larry if I can use that line...... I refer back to the mosquito reference!
I got a kick out of the mosquito crack, too! I am a big, big fan of Zenith shutter dials. I enjoyed doing this radio. Thank you very much for watching and for taking some time to comment! Cheers! Michael
Very nice. Thank you!
It was my pleasure. I really dig Zeniths of the period, especially shutter dials. Thank you for watching. Cheers! Michael
Damn! wish we had a store even close to that , we had one up until 3 years ago and the closed as no one was servicing any equipment and even then it was no way stocked with parts like your store is
We are very lucky here in Salt Lake to have a store like R.A. Elco. They do an awful lot of business with local manufacturers and equipment operators that have older equipment and occasionally need parts. In fact, I think those businesses are a large part of how R.A. Elco is able to stay alive. In any event, I try to buy as much there as I can. Gotta' help 'em stay in business! Take care. Michael
I mentioned in one of your other videos. Look into the Russian eye tubes. They are direct replacement except there octal. You always have to rebuild those sockets anyway why not just swap it.

33:00 - Friction tape. Good to see Fred and Company. "Mosquitos in a nudist camp" LOL, I've filed that chestnut away.
Doug in Tacoma
Hey, Doug! I filed that little gem in my memory banks, too. Now I remember that tape and yeah, we did call it friction tape. This stuff was sticky and unpleasant to mess with. I never use the stuff or it's vinyl cousin! Thank you for watching. I always look forward to your comments, too. Take care, my friend. Michael
I remember taping that stuff to the handlebars of my bicycle. After a while the heat would bleed the adhesive and I'd have sticky hands. Good times, lol.
I WATCH YOUR VLOGS BUT CAN NEVER FIND ALL PARTS...LATEST IS THE 1940 ZENITH RENO...WHAT HAPPENED TO PART 4??????????
I would say replace that power rectifier tube, that might even be part of the hum problem, if it is not it will soon fail, most likely filament to plate too and like you said destructively to the rest of the radio and power transformer especially !!
I did. and didn't charge him for it, either. I put in a good NOS unit and kept the rattly one as a demo/curiosity! I finished the set weeks ago. I played it on the bench for a couple of days to make sure that it was good. Or....was it because I love shutter dial sets and I didn't want to give it back...? In any event, the owner was very happy with the set. The day that I told him that it was ready, he reminded me of our plans to set up a Bluetooth aux feed. I had forgotten, but the old Zeniths are easy and are particularly friendly to minor mods like that. His cell phone sounded great coming out of that 80-year-old speaker! Thank you for watching, John. And, as always, thank you for your terrific comments. Take care, my friend. Michael
Good afternoon Mike... I mistakenly made a comment at the beginning of one of your other videos... I will restate my info here.. I have the exact same radio you are working on here. I would like to talk to you about restoring it. I live in Utah and could get it to you without any problem. Can you give me any way to contact you regarding this quest. Thanks, Kay, N7KH
Hello, Kay! Thank you so much for your comments. I'm easy to reach. You can send me an email, if you like, at thattubesound@gmail.com . I will look for a note from you.
Cheers!
Michael

MAPLIN UK is gone for good, just like the COSSOR radios, That is why I will never trust a SONY, is there a Svetlana version of the ZENITH vacuum tubes that will work in a ZENITH radio.
I have two Sony a6000 and one Sony a6500 mirrorless cameras. They have the same sort of problem with battery life - too stinking short! Not only that, but the stupid things heat up and shut down on overheating protection fault. I think that I'll put the lot of them and all the lenses up for sale. With such miserable battery life, they don't do me much good, spectacular as the image quality might be! Thank you for watching, David. I am very grateful for your comments, too. Take care, my friend. Michael
