You finally convinced me just signed up and look forward to learning. even more! thanks.
@@ve3dvy Welcome aboard David!
Same here, I’m signing up and doing the $20/mo, I could use the help on a couple projects.
Truth be told! You might not realize it yet and I'm calling it, you will be remembered throughout all time for the work that you are doing here! Your name will be just as synonyms as Einstein and Newtown are in their own fields of interest.
My family alone knows you on first name basis! And they have never watched a single video of your work!
After each video, I'm walking around the house saying Paul Carlson this and that! You have essentially become a household name in my house LoL... The trouble with humanity is that it takes too long for humans to recognise excellence and give recognition to where it's deserved most! This is Nobel prize winning stuff right here and instead we give it to people who think they have discovered Quark's?
I don't know what you do when you are not working on these videos but I wish that I could help you to continue your work but unfortunately I'm not in any financial position to do anything about it at this point of time. I like a lot of other people are addicted to your channel and can't wait till the next one arrives...
Thanks for everything you do!
signed up for patreon some months ago now, well worth the money of my daily coffee. A no brainer for such awesome content!
Kind of OT. I am deaf. I hear only with the help of a cochlear implant and it's not a 100% thing. I wanted to let you know from my standpoint how appreciative I am of how clear your speech is. The moderate speed and great annunciation is so wonderful. Together with the excellent audio quality of your vids, I can give you a "599" report and relax, listening without the closed captioning. No one who is not deaf could ever comprehend how this little detail makes the world of difference to me. Many thanks, M.C. - Tom
Thank You for your kind feedback Tom!
I can still hear my Lab Chief back in the 90s: “Turn down the intensity, you’re going to burn the phosphor!” Of course none of us technicians ever did.
Yes!!! It was "a must" in every lab session we had ...and sometimes we got a fine because we forgot to keep the brigth low
My dad had one of those and I'm almost 70....
“It lives when it leaves”
You have the name of your auto-biography.
Or a new horror movie, one or the other.
You are what they call "a Legend of youtube"
bro keep up the amazing content!
From South Africa
i love that Mr Carlson is doing his best to pass his knowledge to future generations to keep this tech alive. keep up the good work
When a teenager I mistakenly touched the capacitor on top on one of those old globe tube radios. The older the radio looked the more I wanted it. My bedroom had a bunch of old time radio circuit boards. Some would run but others not. The capacitor shook the muscle on the back of my arms. This was in the early 60's. Wish I had those radios today.
Never gets old watching these things come back into service. That scope in particular would be an awesome teaching tool as well. No "Auto" button here! 👍
And it's beautiful, seriously, analog electronics were happy to show off what they were
Nice! This is in such beautiful shape! You’d ne er think it is that old.
Hi Marc. Ya, this one was in nice condition. I have another one with "poop" still on the case from a barn. I didn't want to bring that onto the lab bench, LOL! I look forward to your next video!
I love finding that one of my favorite RUclipsrs has commented on another of my favorite RUclipsr's video lol. Love both channels and can't wait for the next videos!

@@MrCarlsonsLab It could be worse. As a Navy Electronics Technician at the Midway Island Communications unit, I got a part time job in the Navy Exchange TV/Radio repair shop. A regular shop that repaired consumer electronics sold in the Navy Exchange store or anything else people brought in. The guy in charge was a GCA technician (Ground Control Approach). Along with the spray cans of tuner cleaner and freeze spray was a can of Raid. I asked why. He said to just wait and see. One day one of those 5 tube plastic kitchen radios came in, covered in kitchen grease, and when we opened it, roaches emerged and started scampering about. THAT is what the Raid was for.
the master of electronics is back with another great video
So excited! I've been checking back almost daily for the past two weeks for the next video. Your content is excellent and very, very appreciated. Thank you for everything you do to further the industry and to give back to those who are just beginning/tinkering.
As usual, like a doctor examining the patient. Mr. C seems like he's in an especially good mood for this video. Nice to see.
It never ceases to amaze me HOW much can be done with so few "valves" or tubes as you call them. I LOVE valve stuff, memories of WW2.
Muntz brand televisions seemed to have very few vacuum tubes compared to most others.
1930. 91 years old and...(even if serviced in 47, one month before the birth of my Dad lol) and it's working !!! Surely they knew how to design and build things back in the day !!!!! Another great video Paul, so perfect and inspiring to start my electronic week 😁
Watch makers/repair put papers inside the watch cases with dates of cleaning or repairs. Later they scratched the same info onto the inside of the watch cases. Looking forward to this rebuild, Paul.
It's Feb 28th 2024, that kit over 90 years old. Amazing, well made simple as and long lasting.
Sir thank you 🙏 your content is mesmerising
My pleasure
All that history...great project. I was an Electronic Engineer for 18 years in England.
I really enjoy watching your methodical approach to your fault finding. Reminds me of me 😂
As someone who knew little and less about electronics, I love watching your videos - thank you so much! And I love looking at all the old electronic equipment too!
Thanks for watching!
I presume Mr Hewlett and Mr Packard were still at school when this was on sale
Maybe. Maybe not. Dave and Bill graduated in '34.
I love the way you describe things in a way anyone can understand.
I love your videos. It's like listening to my mentor back when I did my apprenticeship 30 years ago
I bought one of these in an antique mart in Florida maybe a decade ago. Hooked a wire to the back allowing it to trace, and it worked with no effort. Sold it off on eBay for about what I bought it for, as to not collect too many items. Regret selling that one ... was an interesting find.
Makes me wish I knew what I was looking at as a kid when my dad was repairing TV's and VCR's. So much vintage stuff came through our house and I thought the tubes, nixie's, bulbs, etc were so cool, but I was only like 8- 10 years old... I'd walk around flea markets with him and there were a few gear sellers also slinging "outdated" repair gear.
It looks like the old oscilloscope and I are both doing pretty well since we both came to be in 1933.
A few caps and it will be ready for the rest of this century :)
Gene it’s really great you are on the internet, your generation is underrepresented online, and like so many things taken for granted - once it’s gone it’s gone.
@@christopher3963 Thank you, Chris for those kind words. I hope to be staying around for a few more years.
Them: 1930s Electronics- Will it Work?
Me: Only if Mr. Carlson gets ahold of it.
Absolutely love the glow of those filaments. They just warm my soul.
Astounding how such tech came into being a relatively short time after electricity was discovered and put to use.
You gotta love that old testing equipment. Great video!
Thanks for stopping by!
Given as a gift. A Toledo duck crystal radio w/ Sylvania diode along side a Galina diode. It's 100 years old and used it to listen to a foot ball game recent. The ham was very elderly. And asked me to take care of his "rig" in the mid 90s. It's now 2021 and still running. To day. De kv4li 73
My Dad had one of these and I still have it. Growing up my Dad used to work on all types of electronic equipment down our basement. Car radio's, tabletop radio's, phonograph, TV's etc.
I used to watch him and learned how to repair everything at 7 years-old and now I am 58 years-old.
Thanks for sharing your story!
Fascinating detective work Mr. Carlson. From decades ago the story emerges.
Thanks Mary!
Great video on a great channel!! I just discovered you about 3 weeks ago. I've binge watched about 20 videos on a 50" TV screen. My wife calls you the "boring capacitor man", but I Love it!!! I was a Navy Radar Technician in the mid 1960s and post Navy, worked as a computer engineer for RCA (at Harrison, NJ) , Univac, and finally GE. Although I retired 21-years ago from GE, and am now in my 70s, your youtube channel has awakened a desire to restore some old vacuum tube test equipment......
As a young boy I used to play in the woods behind the Allen B. Dumont Labs on Bloomfield Ave in Clifton/Passaic, NJ. and today's video really hit home!!!
BTW. Allen B Dumont, in 1932 in NJ was the inventor of the 'Magic Eye Tube' as well as a pioneer in Radar.
Keep up the good work, I'll be binge-ing on more videos in the coming weeks.
Bob
Welcome aboard Bob!
Professor Carlson does it again with another great video. Great seeing this old testing equipment come to life. Many thanks !!
Thank you for posting.
You're welcome William!
thumbing through Mr. Carlson's videos and found this gem! this is awesome
You are so right.... Mr Carlson If you can't fix........it's not Broken So awesome to watch you
Great motto - "If it's dead when it comes, it lives when it leaves!" Wish I'd thought of it back when I was fixin' for a livin'. Hope to build your capacitor checker soon. Thanks for the fine presentations!
17:06 that is precisely why I go for older stuff whenever it's practical for me to do so. For all its inefficiencies and bulkiness the old stuff will just never die. It will usually still function and even if it's malfunctioning it can be easily and quickly repaired, unlike modern stuff that's just 'discard and replace'.
My electricity is hydroelectric/nuclear anyway so I don't have carbon worries either. Win Win really.
Re old equipment: I can't tell you how many times I've found it was operator error. I started a new job in 1997 and as I was being shown around for the first time, the guy I was replacing mentioned, "oh, that's broken, that doesn't work... been meaning to send that out for repair, etc" to at least 10 different pieces of gear. In the months that followed I could not find one piece of equipment that was damaged or defective in the slightest. It was all operator error by a guy who just never bothered trying to find out how to work the gear in the first place.
Saw that in a 1930's SciFi movie.... :)
That looks almost exactly like the one I had when I was 14 !!! That was in 1967 and it was given to me by a bell telephone service guy. And yes... it worked.
Thank you for re-awaking my love for electronics. Great channel!!
Glad to be that inspiration!
BEAUTIFUL! Simply BEAUTIFUL Paul!
Looking forward to getting my EICO 460 up and running soon.
You ARE "The Tube Master"!
Patrick
Holy cow! 80 years old and that thing still has sync. That's amazing. The oldest I've ever used was what my engineering professors called "Stanley Steamer" Textronics scopes on those big carts that we still used in our college labs in the 80's.
Bob Sykes , If you look around, Paul has a number of scopes from Tektronics which are on carts because of their weight and size.
Mr. Rogers is the best. Thank you.
I am glad you posted a new video, I was watching old reruns of yours from 5 years ago while waiting for a new one. Good to see you are still bringing these old marvels back to life!
Always a joy to listen and watch your videos! I sometimes put on one of your longer videos to fall asleep to.
Real fascinating to see this old equipment come to live again !well done Sir
to see the hand writing the same in the writing of repair dates from the 40s to the 60s shows it was the same prepair person or owner.. crazy to think about
That's awesome. I just bought an old Hameg HM 112 / 312-6 scope , replaced all caps, repaired some small defects and it's working! Great machine from 1976.
Got some linearity problems, but nothing new caps wont fix.
Kinda amazing that it just fired up like that.
Now I can't wait to tear into my WO-33C. Thanks for the inspiration, Mr. C.
These videos are amazing! Thank you so much Mr. Carlson.
You are very welcome
Paul,
As always, another excellent video from you! I always appreciate the thoroughness with which you go through the details of all the important things that need to be considered and aware of in working with the older vacuum tube equipment.
I also am amazed at how well this thing worked without doing anything to it. The thinness of the line, the brightness of the CRT, other than the bent chassis and the discoloration and missing handle on the outside, this rig is in amazingly fine shape.
Really looking forward to the restoration on this one...and also eager to see more on the BC348 receiver!!!
Dumont goes way back, I used to work on some of the TV's they made and they were built like tanks!
I have an old Eico scope and is similar to this one. I haven't used it for a while and this gave me the want to get it out and see if it still works . I recapped it back in the early 2000's and it was a good general purpose scope!
I have a 1960s one
This piece was clearly loved through it's time. -GOOD! It's supposed should be like that. :D
Thank you much for showing the story. The history is part of it...and that old flux. Can't get that enough of that...
So clean! Beautiful.
Thank you Mr. Carlson!
My pleasure!
Thank you! I always enjoy your chats. I was lucky enough to have a dad, who would build Heathkits to get equipment. I got involved as the oldest. One voltmeter - swipe dial - tube I think was my go to as I learned. Switch circuits and voltage scale, were easy to see and understand. A full scale would only tap the needle. These last 20 or 30 yrs with the DMM's. Most do not understand that the time delay to read the issue may fry the boards inside before you ever know to stop. Looking forward to the build! Cheers Mr C.
Great video as usual. Thank you. Looking forward to the full restoration video.
Mr. Carlson is spoiling us. That radio restoration....now this. I usually give a like as soon as the video starts.... Mr. Carlson never disappointed!
Just wanted to echo all of the positive accolades of fellow followers and add that I love your pride in craftsmanship attitude that you impart. It's refreshing to see no matter what vocation it's coming from. Thanks!
That was so cool to see it come to live, thanks for sharing.
Great video! Your name was mentioned by Grant Wyness on soldering smds. He spoke very highly of you and your capacitor tester! I also saw your name mentioned on Antique electronic supplies website. (positively) Thank you for all your service and thank you. I will look into building one of these in the future. Good luck. I can't wait for a follow up on this!
It's nice to see some of these things in person. I worked for an electronics supply company about 30 years ago and it was my job to look through schematic books and find part numbers for people and either find them in stock or order them for customers. SO I've had extensive use of schematics. We also sold the schematics to a lot of old electronics.
Oh man! I love this scope! And you are more than right - there is so much successful and meaningful work one can do today with it, most people just don't imagine. Not having a calibrated grid and sweep, nor markers, does not rob you of the capability to "see" the voltage. Anyway, these days its not hard at all to give this scope a small companion - a time and voltage calibration box, which would allow one to calibrate the screen before measuring. Great piece, and I cannot wait to see it shine after your hands do their magic. All the best! Bill
Each time I watch one of your videos, I'm always very impressed with the expression of your knowledge and skill. It has obviously taken you many years to acquire this. Keep up the good work.
Thank you very much for your kind comment Mike!
Hi Mr Carlson's Lab
Inspirational.
Due to your videos and a bit of lock down (sigh) in the last 6 months. You have inspired me to pick up my electronics and start doing electronics again. The result is repaired 1 battery radio receiver. 3 mains valve radios, 1 solid state transceiver and assorted other electronics on the shelf to be worked on. Purchased 1 de-soldering machine, how on earth did I ever manage without one of these. In the last month decided to get my HAM radio exams out of the way. Then I will be off to Patreon, I must have one of your capacitor testers and your no contact probe, that will save a lot of time.
Sincere thanks to your self and your brilliant videos. Oh and in reference to one of your older videos, hysteresis (his-ter-ee-sis)
To Carlson I was watching your video about your restoration on 1938 De forest 7D832 radio it was very interesting the radio is handsome I am a collector of pre-war radio’s one of my favourites is a pye type mm made in the early 1930s that Cambridge in the uk . We had one in school . My mother use to work at pye
Thanks for sharing your story John!
This thing puts the "tube" in RUclips :)
that's from the time where you actually owned things. "you" = not yours, "tube", its not a tube.
Very good! Fantastic Equipment!
I've learnt more about Vacuum Tubes and the technology from Mr. Carlson than I did from my actual electronics class teacher. Dang.
Awsome man, thank you for spread out you valuable knowledge.
My pleasure!
Discovering the story is the best part of digging in to any old thing. I've discovered quite some stories hidden in my bus.
Many many years ago, I threw together a Heathkit oscilloscope. However, it came with a solder supply, but whatever it was, it did not have the usual flux. Whatever it had, it literally ate away the PCB's, each beyond repair. Years later, I threw together a Heathkit Hero 2000. This time I used my own supply of solder. My 1986 Hero 2000 is still working to this day. Although there was a flaw in the motor control board. When in sleep mode, the main +5Vdc was shut down, but a sleep mode +5 Vdc was still active for basic functions. But that sleep mode +5 Vdc was not connected to all of the the motor control board IC's. So the IC's that were used to connect the motors to +12 Vdc and GND or vice versa, to determine the direction each motor was running, now had no +5 Vdc supply. But they worked, most of the time. The signals fed to these IC's had now become the power supply by providing current to the IC through the input protection diodes. But when it failed, the whole motor control board went up in smoke due to the +12 Vdc line now being connected to the GND, rather the path being through a motor. I managed to fix the board by replacing the damaged parts, twice.Once finding the cause of all this, I informed Heathkit of this problem, and so they kindly sent me a new assembled motor control board, for free.
Geat audio! Great video!
Thank you so much.
Mr Carlsons lab your Electronics from the 1930s is cool 😎 👌 👍
It just goes to show you just because something is old doesn't mean it can't be useful. Thanks for sharing Paul.
Excellent and interesting! My humble thanks.
Great information.
Mr. C. Thank You !
There are chances that making some wav files of the initial "Hi everyone and welcome to another episode of Mr. Carlson's Lab" from some different videos they can be binary matched. Love it. Thanks Paul, I'm learning a lot from your videos, here and from Patreon. My lab is growing well thank to your inventions. Great respect! (Sorry for english mistakes, if any). Go, go, go!!!
You are a Genius !!!!!!!!!
Crazy to think my long deceased dad was four years old when this was made.
What a handsome device. I guess they used one of these to make the thirties version of Frankenstein!
My first personal scope in 1979 was a Dumont oscillograph. There is a sync function, not a trigger. I paid $50. At work in the lab they had Tec 465s. The Dumont was not as useful as it was fun to operate.
I love it. Thank you for a truly interesting video. I really appreciate what you do.
Thanks to your channel here I just picked up a 500 series tektronix scope in a local ad.. Partially working, Cant wait to get into it.. I have other test equip but need a variac next.
Your electronic inventions is absolutely in genius
A very nice explanation. Congrats. The oscillograph itself looks like being of a very good quality.
Very clean and unmolested inside, great to see. I was pleasantly surprised to see it fire up and function. Not only built to last (a bit cliche) but built to be serviceable - even if that's on the kitchen table.
I love this old equipment.
1930 electronics works flawlessly
My 2018 i phone dies 2 years later and near unrepairable.
Fantastic!
Hi Paul - I too am amazed at how many ancient items (un-messed with) actually 'live' ! Love that old Dumont 'scope.
I have a WW-II A.C.Cossor Mod: 3339 'scope + a later Philips Mod: 5655 which still work o-kay, probably a few leaky caps to replace by now, I imagine. Thanks for the insightful video. - Best 73, de Tony in S-Africa...
I have an Allen-Dumont 304-H and for its years it is functioning very well... They were leaders for this market before the advent of Tektronics ;)
Good afternoon Mister
Marvelous item !!! and fantastic construction !!! what the difference with today ....
Good job and explications
thanks for the share
Eric from France
Thath old Scope 😎 Real nice, hardly any new will last 1/2 as long.
Fuse was replaced on the day I was born. I think mine is overdue as well.
great video. I like the old test equipment also.
Love your videos
I am building your test tools, and conserving / upgrading vintage British equipment. E.G. Cossor 1039M or CT52 miniature O'scopes. I find that some upgrades are required in order to make them useful for low voltage testing: swap the Y amplifier valve for a more modern high slope RF Pentode to increase gain and bandwidth: remove diode valves and selenium diodes and replace with silicon, then adjust load resistors to compensate for the changed voltage: add a sync amplifier: add a HT surge suppressor to keep HT voltage under 400 V. Or alternatively make any power switch on the instrument switch HT on/off to permit first powering the valve heaters when powering from the mains.
Nice one Mr.C..Great how she worked right off the bat. Love your explanations & tips...Thank you for sharing..Ed..U.K..😀
Glad you enjoyed it Edward!
Nice one Paul! Interesting, as always.
Many thanks!
