What I think I like most about your channel is that you treat a repair as a repair. You do the diagnostic, you check the components, and you explain the work. It is what it is, and you keep it that way.
This is definitely a testament to the flexibility of tube equipment being able to work even when almost everything is bad. That's one reason why i still like the old tube stuff.
Locktal tubes were designed for mounting in automobile radios, to keep the tubes from vibrating out while the car was moving down the rough roads of the time.
The 'correct' way would be to order the replacement parts from the manufacturer. Since that is no longer an option the 'right' way is to do whatever you need to do to get it working without using modern parts. There are many 'right' ways to do almost any operation. Those who are complaining has never tried to repair a 50 year old wafer switch! Great videos!
I think that old radio is worth rebuilding, they do not build anything that would even come close to the quality of those old radios now days. It is a real piece of history and its amazing that it can work that well as messed up as it is.
Greetings: Replacing the selenium rectifier: use a silicon diode (1N4007) followed by a 22 mfd 200v electrolytic cap replacing the dropping resistor (cap + toward the diode cathode and - to the first filter cap). Saves heat and no wasted power! Those battery operable radios are usually classified as "farm radios".
I really like that old set, I think if it were mine I would do the general rebuild to see how great it worked back when it was sold NEW and everything was where it was designed to be. Of course that's just me, an old fart who loves the old days when everything old was new!
I have always loved the bass, even now when much of my hearing is just a memory, I still use my cell phone to enter my hearing aids and adjust the bass high and lower the highs, however most recently I have been adding more highs just to understand the words and pick up the different instruments in the band. I still love the old Rock and Roll from my youth the 60's and early 70's, especially the tunes that we listened to in Vietnam, brings back the memories of my old Army Buddies, most of who have long since gone on to their reward. I did get a call from one of them last night, just a check in call to see if I had the virus yet or not. We have been in contact since we both got home, and even visited in person a couple of times now, in fact I had plans to visit him in Idaho this summer, but it looks like that will be out of the question now what with the limited contact orders popping up all over the nation. I wish you good health and have fun with the old sets, I know I love watching your repairs, and I have learned a LOT from watching. I have always maintained that if you can learn at least one thing new every day, you will stay younger, and your brain will stay healthy. I asked my doc about that two days ago, his reply, "What the hell? Who knows, if you believe that way, then it will probably help, and we all know it couldn't hurt!" The newspeak from one with the MD behind his name.
this radio seems to operate like an old wooden barn: Everything is half broken, bent and or just missing... and it is still standing and doing it's job, at least most of it.
Today's folk would wonder how we ever would put up with a radio like this.But if you were in a hunting cabin way out in the sticks and a blizzard penned you in for a few days,this was the only thing playing.(If the power was still on!) And it was beautiful because cabin fever is real. Of course I'm talking about the 50's when communications in this country was spotty. So,nostalgia or not- anybody that can repair these radios is a genius,IMHO Lucky I can solder. Great entertainment.Thumb up
I love radios that are simple and different.,like your three tube Arvin,I have tried to find one I could only find the midget four tube arvin radio,I do have. You find and repair some very cool radios..
My full respect to you for sharing your mistakes with us too. So we can benefit from you great knowledge and learn together from mistakes. Thank you very much. 👍
I like these types of portable radios and it would be interesting to take a bunch of them to a fringe signal area and see how they perform. It's been my experience that, when working right, these battery radios are fairly hot.
Fascinating repair and video - as an artifact, this radio covers at least 3 periods in US history. Someone didn't want to consider life without a radio.
Just me nice to us that had to make in house repairs back in the 70's and 80's. Granted I cut the open cap loose in case it shorted. If I had to use a 1n2005 to 2007 my minimum drop was 47 volts here in South MI.
I love the early luggage-type radios, but they can be finicky. Occasionally you turn them on and get nothing. Then you need to wiggle the tubes and you're back again. Also tubes are totally unforgiven. You MUST hook-up the batteries correctly or ZAP! They're all toast. I did that twice! You're set is a less common example. Those smaller obscure models are my favorite.
The "outside foil" end of the cap is the shielded side. This side was meant to be connected to the ground, (or lower potential end) in order to reduce hum in the set. Unfortunately modern replacements don't always mark this end so it is impossible to tell which lead is shielded without testing it first.
You've done it again! You not only zap the heater but understand and describe why before devising a method to prevent it. Your video's always show something intriguing. Thanks!
This great, better than just a blanket swap out restoration. This is the kind of job I can learn from. Real radio tech and practical understanding of the circuitry. So much fun!
It's very interesting watching these videos. I do guitar tube amp stuff myself, never tried messing with old radios, yet. There's such a huge range of circuits, tubes, etc on those old radios.
Interesting repair video. You are very creative when it comes to getting something fixed. But it's a testament to old radios that even though the components were so far off, it still worked somewhat. Tube equipment is great stuff!
Good to know about the one volt heaters, I've got a AC DC RCA with 7 pin miniature tubes that I blindly pulled out to reset them with the power on. Thanks for creating this video
im sure those valves had 1.5 volt heaters, so all in parallel to work from single 1.5 v battery. the ht if i remember was a 90 volt battery, needles to say the batteries cost a fortune, in uk anyway, and didnt last very long.
Nice repair. I never cared much for Loktal's but have repaired a couple of Philco's that were all Loktal. Having different bases meant that you had to buy only certain tubes from said maker.
SO......... The repair you did was on par with all the other repairs that have been done. In some 35 years from now an someone else gets thi and it’s not working correctly he is going to be amazed at the repairs done.
If you're re-tubing, replace that bodge with the tube rectifier! The output tube should be a 3Q5, the 1Q5 is a 100ma filament, the 3Q5 is a 50ma filament. IE: The 1Q5 is like a 3Q5, but with the two sections of the filament in parallel (3Q5 has a center tapped filament.
Wow that's a radio??? If you turn it on will you hear Churchill speaking???Lol- wouldn't that be Trippy ??? Did you know that everything that is broadcast will eventually travel way out into.outer space??? No more weed gummy worms for me tonight & How the frig did I get here watching this??? But I'm fascinated! !! Can't take my eyes away -I think its that guys voice!!!
I'm not understanding the repair techniques here---it actually takes more time and effort to engineer a work-around then it does to just install the correct parts.
0:23:45 Ron Lyons of Joe's Pinball Channel, is fixing Clocks and an occasional Radio. restoring a 1946 Bendix AA6, gives 'Props to our Venerable Host, here: "..as Shango would say, this Cap is BAAaaked."

But I'm fascinated! !! Can't take my eyes away -I think its that guys voice!!! I'm a physicist and these old capacitors are nifty!!!
Was wondering when I saw this video posted under CZcams video, I always watch your vids only on your channel. Seems like this particular vid is popular as a mix.
in a lot of cases the resistors going high wont make a jot of difference, especially a grid to ground on an output or preamp valve/tube.. those 'dogbones' are usually 20% tolerance or even higher anyway..
I know you guys have a lot of stations where you are but it seems like the sensitivity really went up. Too bad you have people stealing your content. Jerkville keeps pumping them out.
It sounded better with the higher filament voltages. Maybe the last repair person didn't care if the tubes were decimated in short order. Cap replacement would have been an expensive job and the customer might have said no, but a 'quick and dirty' repair would have rang the cash register. Were there really unscrupulous techs back in the day, or was this one just stupid?
I think its a good idea to keep the original capacitors in there and series new ones in to keep the purists happy. If they get upset take your new ones out and solder the leads of the old ones back and show how it does all original 😆. I'm a realistic purist but some people are just ridiculous about it
I have a 40's RCA Victor "Ivory Beauty" radio model 56X2 that I'm trying to restore. This is a botch job with all of the caps and well, everything was poorly replaced so there isn't anything where it should be so schematics are useless. I don't have the equipment that you have, nor the advanced skill level that you do. Is there a way that I can contact you so that you can get it working again? You can make a video of it, and I'll pay you for the fix. I am fixing the Bakelite case which is in rough shape, so all I need is to get it working. PLEASE let me know! You are an expert, and I'm a novice. Thanks.

always love watching the heavy hitter radio repair people....if I only knew this much ....
Keep watching, and one day you will realize that you have learned that much!

the problem with old radios is they pick up modern broadcasts.
That radio has the Great Depression written all over it, just by looking at its appearance.

Somehow, when I first saw that radio, I KNEW it was a battery/AC set. It looks like the last of the 'farm' radios.
I like these types of portable radios and it would be interesting to take a bunch of them to a fringe signal area and see how they perform. It's been my experience that, when working right, these battery radios are fairly hot.
Some have rf amp ( 3 section tuning cap .) Trans oceanic good .old philco most sw.radios.

"making this toilet flush again" well said :D
amazing seeing parts sold in cents.
The "outside foil" end of the cap is the shielded side. This side was meant to be connected to the ground, (or lower potential end) in order to reduce hum in the set. Unfortunately modern replacements don't always mark this end so it is impossible to tell which lead is shielded without testing it first.
Thankfully "Mr. Carlson" has a video out there that can show you how to build a simple checker to find the outside foil and mark it yourself.
@@JerryEricsson I might be 2 years late here, but could you share a link to the video?
Shang, y,ou & radiotvphonenut are my heros
Dont forget DIODEGONEWILD, and very strong accent
You've done it again! You not only zap the heater but understand and describe why before devising a method to prevent it. Your video's always show something intriguing. Thanks!
i like how you built the tube adaptor .., i also enjoy your humor , as well as your shows ,,
This great, better than just a blanket swap out restoration. This is the kind of job I can learn from. Real radio tech and practical understanding of the circuitry. So much fun!
It's very interesting watching these videos. I do guitar tube amp stuff myself, never tried messing with old radios, yet. There's such a huge range of circuits, tubes, etc on those old radios.
it is practically instant on with the direct heated cathode s, and the solid state rectifier.
shango066 - you're the only one!!! nobody could copy you! Don't worry about the free-riders. They could never replace you!
Thanks Shango for the "Don't do it this way" video
Interesting repair video. You are very creative when it comes to getting something fixed. But it's a testament to old radios that even though the components were so far off, it still worked somewhat. Tube equipment is great stuff!
I know that this is an old video, but if it hasn’t been said, Radio Doctors was in downtown Milwaukee.

very nice vintage radio I like vintage stuff like that- that game is called operation
The caps marked "Micamold Radio Corp." were cheap when they were manufactured.
The locking tubes were first designed for car radios, to keep the tubes from jiggling lose from the vibration of the car.
Night Vision ~ That's Kool ! I would have never thought about that ~ Now I'll question more. = ]
Love your vids. Thanks for inspiration. Just fixed up my 50's clock radio.
shango you are pure awsomeness
Synthematix Of cause he is, Shango is the best.
I never understood why Radio Disney is AM. Kids don't listen to the radio let alone AM
It might have to do with AM can reach pretty far
Just noticing the phone number on the repair tag you showed.
I like your honesty when you let the smoke out..lol...
SO.........
The repair you did was on par with all the other repairs that have been done.
In some 35 years from now an someone else gets thi and it’s not working correctly he is going to be amazed at the repairs done.
Jeff King he or she will probably find a 40 year old video of their radio getting fixed!
Those "Micamold" cap's were junk on the day they left the factory.
If you're re-tubing, replace that bodge with the tube rectifier!
The output tube should be a 3Q5, the 1Q5 is a 100ma filament, the 3Q5 is a 50ma filament. IE: The 1Q5 is like a 3Q5, but with the two sections of the filament in parallel (3Q5 has a center tapped filament.
Its a 1A5, did i say 1Q5? Yea that wouldnt work
i think shango066 videos are an unbelievable xmas gift! =)
Wow that's a radio??? If you turn it on will you hear Churchill speaking???Lol- wouldn't that be Trippy ??? Did you know that everything that is broadcast will eventually travel way out into.outer space??? No more weed gummy worms for me tonight & How the frig did I get here watching this???

What's with the random german commercial?
Great video!! I like the looks of the new tubes.
No sell by date on these videos.
All useful stuff
That is actually a silicon rectifier. My old Heathkit CD-1 colour bar and dot generator has two of them in it.
I'm just wondering what guys are going to to with these wonderful old tube radios when the Am signal is Digitized?
Enjoyed this and your other videos Shango. What do you do with junk like this afterwards?
fantastic vdeo shango, bob here in uk
Very old nice radio. Never seen one like that before either considering it looks like a box wrapped in 50's or 60's wallpaper. LOL
Beleza. Esse é um clássico! Rio Brasil
just in time for Christmas music
Now I know how I killed my hallicrafters TW1000. Thank you for the wonderful details.

it doesnt get past the firmament but it's remembered in the field..
Let me know if you need any of those tubes..... I have a lot of them! I'd recap it!
Dionne Warwick!!!!
Warwick guitars.
So you're saying the capacitors have turned into resistors and the resistors have turned into capacitors so why wouldn't it work?
Can you image getting a new variable capacitor for $1.39?!
Previous tech may have sprayed the volpot generously, and it picked up old lube, oozed out and dried.
28:04 what the...
Love the cluster F. What do you think about making a video about foxhole radios?
nice cute old radio
I'm going to rebuild oid radios and sell them. is there any way I could make them safer?

Way cool video! One of those Delco tubes looks like it overheated as the plate had a bluish tinge to it.

470M = 470K ohms. Interesting and good to know. Thanks!
RyuDarragh thank you for the information. Very interesting history of electronics abbreviations!
You 're smart and funny as Hell!!
Someone butchered that thing, sad, hate cleaning up other people's mess. That radio is worth fixing correctly.
I want to buy it and replace all those parts. I feel sorry for it.
What's cool,is cool!
What are the sandy things supposed to do???
It's another type of resistor.

you didn't happen to get that from the TRW swap meet?
Excellent video but why is your videos listed under comedy instead of electronic or other options?
Cali traffic broadcast 😊
good vid shango066
Hello: is there any way you can help out on my pioneer Qx 9900 reciver from 1972 !
Dirty pot. Or warm out.
@shango066 why dont you create a radio station taht broadcasts royalty free music that you can use?
i believe radiotvphononut has done just that for his videos.
then he couldn't sweep the dial.
Then we wouldn't hear the random craziness that comes out of California!
thats so true!
