I have one of these exact units. It was my first electronics repair way back in 1968 at age 13. My dad had one sitting on a shelf in the garage for years. I don't know if he ever even had it operating. I asked him what it was, and when he told me, I immediately thought about using it for the amateur radio Field Day that year. But, it did not work, so I took it apart and not knowing anything about what I was doing, I found the capacitor across the AC line was bad. I replaced it with one from his stock of parts. He was also a ham radio operator, and that's where I learned about electronics, starting about age 9 by building a crystal radio. As it turned out, this unit didn't have enough capacity to run the radio equipment, but it fascinated me at a very young age, and by repairing it, I gained enough confidence to continue learning how to repair electronics and went on to have a successful career in the field of electronics, even spending a few years as chief engineer at an AM/FM radio station, all with no formal electronics training, just what I learned as a ham radio operator. I would love to see a full restoration on this unit. I would probably dig mine out and do the same for it. Thanks for this video. It brought back some very good memories of my younger days.
Reminds me of the Honda E300 generator I came across 20 years ago. 2 stroke 50cc, 300 watt output. Got it free as a non runner, got it going, was all proud of myself, then couldn't figure out what the heck I'd want to power that ate less than 300 watts while also listening to a swarm of pissed off bees the whole time, lol. Ended up selling it shortly after, and now that I've gotten full blown in to old cars and equipment, I really regret it.....
i had one as well back when i was 8 years old very interesting. it was when i started fixing tv's & radios in the early 70's i had a tube tester & would make regular trips to the drug store to buy tubes. this brought back good memories 😃
Yep. Thumbs-un on a total restoration. That old piece of equipment is so plainly, sheetmetalian cool. It could have been on the set of Forbidden Planet.
It at least deserves rust treatment on the binding posts and some fresh caps. To be honest the paint looks to be in decent condition, and adds to the charm.
Yes, with all that arcing the wave pattern would be quite tough. I wonder if there is any filtering in the device? If did have the layer on the output wires. Mr C will add a board and make it a near perfect sine wave. He da man! 👍
The big transformer will kill off much of the HF in the output. But the shielding is needed to help reduce HF being introduced in the cables themselves. And the capacitors are very much needed to reduce the radiation out on the 6V leads.
I'd say yes to an electrical restoration, but no on the outside appearance. To me, I like the old look. Thanks for showing how a vibrator tube works! Always heard them in old car radios, but never knew how they did their job.
Back in the 1950's I filed the points on dozens of the automobile radio vibrators-most built before 1940. Contrary to some comments, these circuits were well shielded and filtered. Switching power supply designers haven't learned a thing when it comes to supressing interference. The hardest part was removing the power supply from the car which was usually located in a difficult to access location. Interested in learning about the function of the voltage regulator rotary switch.
Definitely do a complete restoration! Very cool device. Back in the 50s and 60s I used a Ford Model T spark coil to provide the spark to my Dyna-Jet pulse-jet engine for control-line speed flying. The coil stepped-up 6 volts to about 20kv with a set of vibrating points. Worked great!
I say go for it - with all this solid state stuff around, it'll be refreshing to hear the hum of something actually working instead of just sitting there like a museum display.
Appreciating the frequency of your videos lately - the winter is long and incessantly wet in my neck of the woods - a bit of Carlson bench-time is always welcome
@@davelowets you say that ,but i live in one the crappiest third world countries of the world & we get absoulute worst quality products including smps , but i havent encountered any horrible EMI from them . Also , we dont even have earth ground in our homes , we only have neutral & live
@@thevoidedwarrantyalot of the SMPS cell chargers we get in the USA are very noisy with emi, there's something else in my house I haven't yet found thats very noisy really only on my tube broadcast receivers. Only have a couple IC based soild state receivers and they are just no were near as sensitive as the tube sets.
Coming from a car Hot Rodding Family, I learned about vibrators years ago. A switch on the dash to turn them on, and off, two in the trunk wired to two seperate ignition coils and condensers that had the high voltage ran out to a spark plug welded into each exhaust pipe. Set the carb to run rich, rev it up, flip the switch, and you had twin flamethrowers out of the exhaust. Pretty awesome when you’re a kid! And, of COURSE we want to see you restore it. We ALWAYS learn something new from you, and your attention to detail that will serve us well on a completely unrelated project we’re working on.
Thank you Mr Carlson, I’m 70 and had a short career in the uk learning, building and repairing equipment, most I learnt getting hands on and you get the ahhh moment and get a happy customer. I get great joy in knowing you are so knowledgeable and enjoy your videos. Thank you ❤
The manual "regulation" comment reminds me of something that was often said when we were studying electronics at technical college: the output will remain constant when adjusted to do so
Around 1970 a girl in my car asked what the buzzing was and I said my heart, now 54 years later the buzzing is in my ear. ! It was of course the vibrating oscillator in my car radio common at the time. It was annoying so I found a radio with the 12AD6 etc valve set with 12v anodes and built a transistor output stage, glad to say the music plays on. Thanks, a real trip down memory lane as these contacts were a continual source of bother.
You could make your own pretty easily with a d.p.d.t relay, a transformer, and a few capacitors. Getting the frequency tuned to 60hz without the help of an external oscillator circuit to power the relay would be really hard, but it would work nontheless.
Yes please! A restoration would be most interesting - these sort of electro-mech devices show the ingenuity designers had before everything could be done 'solid state'!
Dad had a wide collection of the vibrators that came out of radios, this video sends me back to those days of curiosity and learning. Later in life, I had found a smaller mechanical inverter that had a different sized vibrator enclosed with a considerable amount of foam. It was a truly amazing piece of electronic history, created through simple design.
Definite yes on the full restoration of this gem. Nice to see more old ATR equipment around ! They were certainly durable devices. I have and still use my fathers old filtered "battery eliminator" from the late '50s; model 610C-ELIF. The AC line bypass capacitor has been replaced but the two original "computer grade" filters (4k mfd 15 volt each) are still going strong as are the original disc rectifiers. I use it in servicing automobile radios, portable TVCR / DVD combos, etc... Though it's been a few years since I scoped its output, its always been very smooth and reliable. The single only issue nowadays is the accuracy of the meters. But, I monitor that with separate meters. I don't think it has an internal calibration adjust but haven't looked. I'm reluctant to pull it apart when it still works so well. ATR certainly wanted their equipment to be long lived and it shows. Also, thanks for the demonstration of how you service vibrators. I haven't used that method of entry before but certainly intend to. Great job 👍
I'd really love to see the waveform that comes out of that outlet and an analysis of what devices would be safe to power with it. Thank you for another excellent video.
Nicely done Mr C, the tubing cutter solution was one I hadn't thought of to be honest. Maybe an electronic restoration leaving the exterior as is would be plausible. This is a unique piece meant to be seen and demonstrated, not necessarily used. Another great video down memory lane, much appreciated. Thanks.
This brought back a memory. Back in maybe 62 found a radio that was in a similar box at a trash dump. I remember the sound when I connected it to a battery. OK, I was 8 and stupid. Probably a 6 volt, but connected to a 12 volt battery. The one that he has looks great. The one that I played with, the case was all rust.
I'd like to see a full restoration. The vibrator reminds me of the old tube radio that was in my dad's 1953 Cadillac. They were always going bad. When you turned on the radio the first thing you would hear was the sound of the vibrator until the tubes warmed up and the radio came alive. Brings back memories.
Someone I know had a fire caused by a vibrator that locked up and fed straight DC to the transformer primary. Lots of smoke, but luckily not too much damage to the car, other than the radio.
I've got an old late 40s or 50s military aircraft radio think rx/tx, with the same electro/mechanical power supply. It's built for the military, so it's better constructed, and it's aluminium. It also has on the back of the valve electronics several big frequency crystals. I would have used an even softer cleaning device. Good job it was built when things were meant to last or the contactor would have been damaged, plating, or surface damaged. Yes, please do a complete restoration. I find you are very knowledgeable, thorough and it can be passed on to your viewers. Thanks for the video.
Great find mr. Carlson. I love to see hammer finish this thing... As a matter of fact it was just a question in a german forum of how to do that. Not worth metion actually. Always enjoy your videos and thanks for taking your time doing this stuff. We love you! Stay healthy man!
The oscillator is in fact a relay which get powered through his own NC contacts. A restoration would be nice, then we can also see how the voltage regulation works. Grtz
Yes, a complete restore, as well as scope analysis at various points. I am glad to see more things than radios (not that I am complaining about radios).
In the early 1970's I was a soldier with the US Army. After my year in Nam, I was stationed with the 3rd ACR communications secion. We had radio teletype van that ran on both 24 volts for the radios and 110 for the teletype machines. To get that 110 while on the road or temparorily parked we could turn on two rotary inverters, when we sat up for a long time we started up the 2 110 volt generators that we hauled behind the rig on a trailor. The HQ would tap in to our generators for electrical power in their tents. The generators were 10 KW and ran on motor fuel (gas),
Hey Mr. Carlson... Yes an full restoration would be fun and educational to watch. Meanwhile since a 6 volt vintage car radios also use the vibrator oscillator system, a revival of an old radio would also be nice to see. Your channel has bee of much help to me over the past 5 or 6 years or so in my learning form you what a capacitor is. In the meantime I have resorted a few vintage German radios.
You’ve got to show the output on an oscilloscope. I’m assuming that it’s going to be a square wave. And can you draw the schematic as built really interesting project really.
Very nice 👍 my old boss told me about these when we were talking about a power supply I was working on for some equipment. Never actually saw one in the wild, but he did say they were very unreliable. Cool to see one working, same principal as the old door bells. Cheers, Jake
Hi Paul, I really want to see the continuation of the Grand Receiver Restoration Series. So that's my vote. Keep up the inspiring work! I know its very time-consuming.
Very cool device. I tried wiring up a little reactance demo from the 40-50s to an old 12V transformer in reverse. Was able to power a bulb but it went up and down greatly in brightness.
The cool kids in the 50´s I imagine ran a nice beach party with this. Park the Caddie aside, idle running, open hood, the buzzer with a long ac lead to power a turntable and a radio. Not so much a restoration but a time correct demo (like I mentioned) I´d like to see. Let´s listen to some RocknRoll for a change...
Many of the old vacuum tube car radios of the 50's had a mechanical vibrator device to use as part of the circuit to step up 6 or 12 volt electrical systems to a working voltage for the vacuum tubes. It was a plug in cylindrical device that you could actually hear vibrating if you put your ear close to.
I have a friend that participates in a WWII club. He rebuilds old troop transports and Jeeps. They have meet ups. I repaired his Echophone EC1 and his vibrator. He puts the old radio on the tailgate of the vehicle and runs it with the vibrator. He has allot of fun with it.
In the 1950's a toy train manufacture American Flyer used those tubes for their model trains to generate a 600 cycle tone to mimic the sound of a diesel locomotive air horn. It sounded awful but it was able to superimpose the tone onto track power and play through a speaker in the engine. This video is super helpful for me so I know how to repair those generator tubes. Main difference is the ones for the trains are 4 pin.
Like we say on the Mr.Carlson's Blog: "Don't take it apart... Turn it ON!".. Love the classic equipment. You really are the "Classic Electron Whisperer" My GF seemed interested until she found out what you actually meant by vibrator Thank you for the video. Cheers from So.Ca.USA 3rd House on the Left (please call before stopping by)
What an interesting piece of hardware! Great work bring this to your channel and absolutely a full restore would be awesome, especially showcasing the soldering of the vibrator can. Thanks for your work!
Absolutely Paul,... Please do an entire restoration and include some of the details of making a beautiful rebuild would be something I would be interested in, you mentioned even replacing some of the stickers like on that oscillator I know it sounds simple. But could you at least briefly go over how that's done there could be something to learn, this is really a cool project, I think way back in the day some people were really creative to make something like this with the technology of the time. And the explanation and disassembly of the oscillator explains it all. I noticed the handle looks like it's in very very good shape for something of that age. Again I would like to see this restored how far you go with that well we will see. Restoration techniques are important especially for those who wish to restore something to its original condition, these techniques and possibilities for the restoration definitely need to be explored. Just to let you know I've been a Patreon supporter for many many years. And hopefully I will get my small little repair lab going someday I've collected so many pieces and types of equipment to do these kinds of repairs and the restoration and doing a properly is very important to me and having the ideas and options definitely come into play.
Definitely interested in seeing the full resotration of this unit. It would also be really interesting to see how much noise was on the supply and how good the shielding works. This really shows that technology may change the components used, but the actual principles of operation have not changed much over time.
The first contact was very far gone. However, if the contacts aren't *that* bad (the 4 round contacts are not something that i would've used sandpaper on), first use a piece of ordinary printer paper soaked in contact cleaner. After that, repeat the cleaning with dry paper. Sometimes, the contacts are coated with something and you want to avoid removing that coating as much as possible. This also goes for relay contacts, switch contacts etc.
Yes, please Mr. Carlson show the whole restoration. In addition it would be great an explanation of how it works with the schematics and the logic behind, plus a quality test of the AC voltage produced on the oscilloscope with amount of ripple if it does it. - Will it be better that modern AC generators ? 🤔
Yes, go for the full restoration. I learned how to repair car radios when I was in high school and they still had vibrators well into the 60's if not later. Also still have some points files that I used on my 73 Datsun 240Z and 1970 Jaguar XK-E distributors until I changed them to electronic ignition. Note: Some 12 volt cars were positive ground until about 1964. I had a 64 XK-E and had to use a polarity converter to put anything modern electronic in it like a tape deck.
Cool! Haha. I'm sure you know old tube car radios had a similar "vibrator" or interrupter that drove a step-up transformer for B+. They were actually pretty quiet. Maybe restoring such an old radio would be an interesting project...if one can be found. Their ideas for shock-proofing, compact button tuning, etc. were ingenious. A chunk of my misspent youth was cruising junkyards to learn this.
That is a beautiful old inverter. Thank you for sharing this with us! I have always liked the old vibrating reed devices like this. Would like to see how well the frequency remains stable across different loads an supply voltages.
Takes me back to high school in the 60's. I fixed one of those in the electronics lab, same issue. Thanks for sharing and yes I'd like to see a full resto.
Paul, you really peaked my interest with this old inverter repair video, just getting it working was good enough for me. Don't waste your time on a complete cosmetic restoration BTW: I have the same model of Electro Power supply you used in this video, except mine has black faced meters, 4 Selenium rectifiers and was manufactured in the 1950's. Also have a small 6vdc inverter from the 1950's too (plugs into a cigarette lighter socket) and was meant to power low power devices like an electric razor or whatever, it's rated at about 30 watts.

What happened to the BC348Q Resto? You started it, but I never saw any videos of you finishing it. Maybe I missed them?

@davidbrittenham4631 I love this story! I'd also like to see the full restoration.
26:21 Yes, please do the entire restoration
and thanks in advance
Can you please measure the efficiency of the circuit and show the waveform on the oscilloscope ?
Yep. Thumbs-un on a total restoration. That old piece of equipment is so plainly, sheetmetalian cool. It could have been on the set of Forbidden Planet.
It at least deserves rust treatment on the binding posts and some fresh caps. To be honest the paint looks to be in decent condition, and adds to the charm.
Yes to the restoration please!
Yes on the rebuild! Also would've liked to see the AC output on a scope, loaded and unloaded.
I'd like to see it before and after recapping.
I would like to see that too.
What you would see on a scope is a dirty Square wave with some HV peaks, the capacitors are meant to tame them.
Yes, with all that arcing the wave pattern would be quite tough. I wonder if there is any filtering in the device? If did have the layer on the output wires.
Mr C will add a board and make it a near perfect sine wave. He da man! 👍
The big transformer will kill off much of the HF in the output. But the shielding is needed to help reduce HF being introduced in the cables themselves. And the capacitors are very much needed to reduce the radiation out on the 6V leads.
I would love a restoration, and then an analysis of the the output and the different settings with a scope. What a cute little contraption!

Yes, I remeber that well. Foot to the floor, car ignition shuts off and tailpipe plugs turn on. Those are hot flames, perfect mixture!
Afterburners, just like on the old turbojet engines for supersonic fighter aircraft.

I would certainly like a full restoration of this.
Mr Carlsons lab your antique atr power inverter is awesome from 1950s
I wish they still made these simple machines!
You sir are a national treasure.
Thanks for showing that unit and explaining how it works. They had some marvelous engineering back in the day.

The museum quality collection of working antique electro-gizmos never ceases to amaze.

Me too - full restoration. Love to see you tackle the non-electronic parts (eg. soldering the can and painting the case) .
Hi Paul, I really want to see the continuation of the Grand Receiver Restoration Series. So that's my vote. Keep up the inspiring work! I know its very time-consuming.
Very cool device. I tried wiring up a little reactance demo from the 40-50s to an old 12V transformer in reverse. Was able to power a bulb but it went up and down greatly in brightness.
Yes to a full restoration!
Great video, as always.
The cool kids in the 50´s I imagine ran a nice beach party with this. Park the Caddie aside, idle running, open hood, the buzzer with a long ac lead to power a turntable and a radio.
Not so much a restoration but a time correct demo (like I mentioned) I´d like to see. Let´s listen to some RocknRoll for a change...
Mr.Carlson, you have changed your format and as a viewer I so enjoy it Keep up the great videos! Yes, please!
Many of the old vacuum tube car radios of the 50's had a mechanical vibrator device to use as part of the circuit to step up 6 or 12 volt electrical systems to a working voltage for the vacuum tubes. It was a plug in cylindrical device that you could actually hear vibrating if you put your ear close to.
I have a friend that participates in a WWII club. He rebuilds old troop transports and Jeeps. They have meet ups. I repaired his Echophone EC1 and his vibrator. He puts the old radio on the tailgate of the vehicle and runs it with the vibrator. He has allot of fun with it.
Please do the restoration, awesome video as always 👍👍👍😎
In the 1950's a toy train manufacture American Flyer used those tubes for their model trains to generate a 600 cycle tone to mimic the sound of a diesel locomotive air horn. It sounded awful but it was able to superimpose the tone onto track power and play through a speaker in the engine. This video is super helpful for me so I know how to repair those generator tubes. Main difference is the ones for the trains are 4 pin.
I still have my AF set
.!!!
Like we say on the Mr.Carlson's Blog: "Don't take it apart... Turn it ON!".. Love the classic equipment. You really are the "Classic Electron Whisperer" My GF seemed interested until she found out what you actually meant by vibrator Thank you for the video. Cheers from So.Ca.USA 3rd House on the Left (please call before stopping by)
I would love to see a full restoration of this! Thank you for showing it this far!
Thanks for a great video, once more!
I'd love to see the full restore, please! Cheers, Darren
100% for the complete restore, please. This thing deserves it.
Would love to see a restoration of this inverter along with analysis displaying the characteristics.
Would love to see a restoration on that!
YES! Please restore! Maybe scope it so we could have a before-and-after look?
Yes do a complete restore !!! That is so cool !!!!
Definitely do a complete restoration and show what the output looks like on an oscilloscope!
What an interesting piece of hardware! Great work bring this to your channel and absolutely a full restore would be awesome, especially showcasing the soldering of the vibrator can. Thanks for your work!
I have heard one of these running when I was a kid but have never seen inside it...very cool!
Would love to see this restored too.
Absolutely Paul,... Please do an entire restoration and include some of the details of making a beautiful rebuild would be something I would be interested in, you mentioned even replacing some of the stickers like on that oscillator I know it sounds simple. But could you at least briefly go over how that's done there could be something to learn, this is really a cool project, I think way back in the day some people were really creative to make something like this with the technology of the time. And the explanation and disassembly of the oscillator explains it all. I noticed the handle looks like it's in very very good shape for something of that age. Again I would like to see this restored how far you go with that well we will see. Restoration techniques are important especially for those who wish to restore something to its original condition, these techniques and possibilities for the restoration definitely need to be explored. Just to let you know I've been a Patreon supporter for many many years. And hopefully I will get my small little repair lab going someday I've collected so many pieces and types of equipment to do these kinds of repairs and the restoration and doing a properly is very important to me and having the ideas and options definitely come into play.
Yes, a restoration would be nice to see.
- Thank you
We would enjoy seeing a restoration of this vintage inverter
Definitely interested in seeing the full resotration of this unit.
It would also be really interesting to see how much noise was on the supply and how good the shielding works.
This really shows that technology may change the components used, but the actual principles of operation have not changed much over time.
Would love to see the full restoration of that inverter! Its always a pleasure to watch you doing these kind of restoration! 😁
The first contact was very far gone. However, if the contacts aren't *that* bad (the 4 round contacts are not something that i would've used sandpaper on), first use a piece of ordinary printer paper soaked in contact cleaner. After that, repeat the cleaning with dry paper.
Sometimes, the contacts are coated with something and you want to avoid removing that coating as much as possible. This also goes for relay contacts, switch contacts etc.
Silver. You are correct using paper. I'm guessing with these however there's no silver on the contacts because it wouldn't survive the high arcing.
Would like to see the full restoration please
Yes, please continue with the inverter restoration Paul.
I put one in on my motor cycle once to run my hand made QRP mobile rig in India. Oh about 60 years ago! Love it, Thanks..
Yes, a restoration would be awesome!
Yes, please Mr. Carlson show the whole restoration. In addition it would be great an explanation of how it works with the schematics and the logic behind, plus a quality test of the AC voltage produced on the oscilloscope with amount of ripple if it does it.
- Will it be better that modern AC generators ? 🤔
A full restore video and looking at its output waveform on a scope would be awesome!
Show us the waveform at the output please
Yesss
Fun Video! I learned something new! Please continue the restoration!
Yes, go for the full restoration. I learned how to repair car radios when I was in high school and they still had vibrators well into the 60's if not later. Also still have some points files that I used on my 73 Datsun 240Z and 1970 Jaguar XK-E distributors until I changed them to electronic ignition. Note: Some 12 volt cars were positive ground until about 1964. I had a 64 XK-E and had to use a polarity converter to put anything modern electronic in it like a tape deck.
Paul. Please do a video on restoration of your HP141T Spectrum Analyzer. Keep em coming. Another great video. Thanks for sharing your knowlege.
Really cool old equipment
Paul, thank you...very relaxing while the "World Turns"....(my Mom used to watch that soap opera) may Christ Bless you my friend !
I'd love to see the waveform that device outputs, as it'll definitely be pretty unclean. I really enjoyed this video, thanks Mr Carlson!
Absolutely fantastic instructional tutorial. Thankyou!!!
Cool! Haha. I'm sure you know old tube car radios had a similar "vibrator" or interrupter that drove a step-up transformer for B+. They were actually pretty quiet. Maybe restoring such an old radio would be an interesting project...if one can be found. Their ideas for shock-proofing, compact button tuning, etc. were ingenious. A chunk of my misspent youth was cruising junkyards to learn this.
That is a beautiful old inverter. Thank you for sharing this with us! I have always liked the old vibrating reed devices like this. Would like to see how well the frequency remains stable across different loads an supply voltages.
Thanks, Paul. Sure, I wouldn't mind seeing the restoration.
That's pretty nifty Paul. Thanks 🙂
Thanks for stopping by Dave!
Takes me back to high school in the 60's. I fixed one of those in the electronics lab, same issue.
Thanks for sharing and yes I'd like to see a full resto.
Paul, you really peaked my interest with this old inverter repair video, just getting it working was good enough for me. Don't waste your time on a complete cosmetic restoration BTW: I have the same model of Electro Power supply you used in this video, except mine has black faced meters, 4 Selenium rectifiers and was manufactured in the 1950's. Also have a small 6vdc inverter from the 1950's too (plugs into a cigarette lighter socket) and was meant to power low power devices like an electric razor or whatever, it's rated at about 30 watts.
Things back then had beautiful aesthetics.
Yes to the restoration on the inverter Paul
and thanks for the video
