Hello Mr. Carlson. I have a suggestion for you that might make it easier for you better get an idea of what your viewers (or maybe just your Patrons) think you should do next etc. There is a free to use polling website that I have seen being used on various RUclips channels for several years. Here is the website "www.strawpoll.me" 73 de OZ2BO. Ps. I have been putting off becoming one of your patrons for an embarrassingly long time. This has now been rectified! :-)
(I´d like to see the messy job of de-potting that transformer please;-)
If you're not already, you should be a father. You seem like you'd be a patient dad who could raise some smart kids.
I have a 180, you're a genius. Did you take the IQ tests?
Hey, i have an idea for you that's better than de-potting. If you can figure out where the capacitors are and how they are attached, you should be able to drill through them or their leads, breaking the circuit. You could get this using x-ray. I bet you have some tubes and power supplies good for that at home, right?
MrBrymstond Sure you do buddy.
DEPOT the transformer . . . please ! . . . . . . certainly a bit messy but it would certainly teach us a lot. Your running commentary during the process would be interesting, fun and educational.
I would second de-potting the transformer BUT also request, for the educational factor, to show in one video the de-potting process and then in a separate video showing for this same device, how you would go about scavenging another transformer and making it work. My reason for asking it be done for this device apart from the familiarity from having watched this video, is also because of the interesting design for the transformer they chose with the separate taps and what not which could be difficult without the proper knowledge of how to overcome those issues when grabbing a transformer that isn't necessarily set up with the same taps. Extra work, sure, but I think it'd be really worth it. The other reason I just thought about is what if the internal capacitors had actually been direct shorts to ground and fried the transformer? Then we'd really need a replacement and short of finding an exact match, we'd need to figure out how to grab something and make do with it. Ok, mini-rant done :D Thanks for all your hard work on these videos, Mr. Carlson. I truly do appreciate the time, effort, and care with which you present them to us.
GREAT suggestion/reasoning, thanks.
depotting is a standard practice on NSTs for tesla coils. Did only one and it is a mess...
I've never seen a "tar" device de-potted. I worked for a company when I was in HS that made 600KV+ x-ray machines. Sometimes a Marx Surge pulse generator module would go bad. We had to de-pot the epoxy modules using MEK to find out what went wrong.
Someone do a hashtag #depotthetranformer
Yes, please De-pot the transformer. Can't wait to see what's inside there.
DE-POT! DE-POT! DE-POT! lol, seriously, I'd love to see that process, if it's safe to do so, and you're the man to give a proper demonstration.
"It really doesn't have a choice when it is on this bench - it's going to work again!" - Mr. Carlson is the Chuck Norris of electronic!
Now what most of you lot don't realise is that some of us worked on that old kit when it wasn't old kit and we used the then state of the art test gear, sometimes even designing and building gear to do the job because no one had worked on the, "new gear", that, like ourselves, used to be new gear.
I was an apprentice in the days when audio amps had what looked like a couple of up turned milk bottles as push-pull output stages and we saw in the smaller and smaller glass bottle valves/tubes until along came those new fangled transistors followed by small scale integrated circuits, medioum scale ICs and Larger and even larger scale Integrated circuits.
Then those Large scale ics began to shrink and so it goes on. And no, "A Wobbulator", wasn't the generously endowed secretary of the manager.
He can cut a knife with hot transformer! 😆
I bet Mr Carlson is the only guy in North America that gets a weird old scope from the 1930's and says if it's got a bad crt, no big deal I have a replacement lol
I have three 913 CRTs. And a total of at least 50 other small CRTs. If you are interested, I made video demonstrating many types of small cathode ray tubes, including the 913: ruclips.net/video/bRuqud2j_d8/видео.html
1 inch CRTs are quite common
i watch tons of vlogs on youtube and without doubt this mans vlogs are top notch, im fascinated with electronics and yet know nothing about it
Hhhhhhg guy dry t6666lpp000p0pp
"When it's on this bench it's going to work again" I really love that positive attitude. That is the spirit! Another great video Paul. This is such a simple circuit. Was so much fun to see this old piece come back to life. Really hate it that they stuck those caps in the transformer like that. Would be nice for folks to see how it is done by a real professional. Thanks Paul for this video.
If it didn't the video wouldn't have to go up sooo..
Wonder if he can give my Dreamcast the once over, read a load of tutorials about simple fixes, done them all and it still won't read anything. Oh, well, it was dirt cheap
I want to know,
Where the heck do you find these things?
That Mini O'Scope is over 90 Years Old!
The Radio Shop 1
Don't get cocky, kid.
Thank you for getting right to it. So many RUclipsrs think everyone wants to hear them ramble for five minutes about nothing related to the actual subject.
Please de-pot the transformer.
Ooooh, this is a treat. I love these vintage teardowns. I was just finishing a long day of work when I saw this go up, and now I'm watching before bed. Absolutely turned my day around! Thanks, Mr Carlson!
The capacitor manufacturer Aerovax is still around and making capacitors! No longer in Brooklyn though. I think you should call them and ask for your money back on the leaky capacitor. Only 80 years old and it already worn out.
With the neat graphics on it this might have been one of those times that hollowing it out and hiding a modern cap inside would have been worthwhile.
molson12oz, so... will you replace this capacitor with an identical new one for free, or not? What's the warranty policy dictated by that fancy ISO 9001:something of yours?
:P
molson12oz, yeah, sorry for not being actually funny; it's just that the ISO process certification stuff seems so out-of-place under this video, and reads as if copied from a press release.
Props for being in the industry for nearly a century, though - that's genuinely cool and good to see. Even if your capacitors are lousy ;)
It must be a miracle or a public relations coup d'etat for Aerovox to be so big in their field and yet make crappy caps.Hmmm-I'll stick with the ISO certification of quality-that's not a silly Gov label- it's an industry standard constantly improved and yes- it must be maintained.
But-once a company has earned it due to their insistence on quality it is a GREAT ad footnote.
molson12oz, previously you turned your "satire filter" OFF.
I can only assume it also works as a "satire detector", in which case I'd recommend keeping it permanently ON - because it should have been bloody obvious that my comment was tongue in cheek. Nobody expects a big electrolytic capacitor to keep working for 80 years. Plus, I absolutely love its looks; the labeling is so stylish and classy.
Anyway, I still love you, even if both your capacitors and your sense of humor are lousy :)
PS. I already know what ISO 9001 is, although I appreciate the attempt to educate me. I never claimed it's just a government label.
I know nothing about electronics except to take my items to someone that does for repairs. But I totally enjoy coming to your youtube channels and just sit back and watch you do projects. You explain thing so I even understand. Thank you
Your videos just fly by because they are so interesting and informative, you Sir are a wonderful teacher and I love the way you bring your professionalism to are screens. Another great video I just can;t speak highly enough of you and your channel........Thank you!
i love the "if it doesnt work then we'll make it work" attitude of your videos
So many things I like about your videos, however the thibg I love the most is your walk-through and explanations of schematics! Thank you!
1935!!! Good job, awsome video.
My dad bought his eico audio gen. new and used untill 1974. Your comments about it's quality quantified my belief that my dad new quality. Thank you
Thank you @Mr Carlson's Lab. This makes me with I had snagged the Dumont Oscillograph from my last job. It was just sitting, waiting, for a good home. It hadn't been used in decades.
You're welcome!
You HAVE to de-pot the transformer. It would be unthinkable to _not_ have this little beauty as anything other than fully restored.
It's magnificent!
A lot of this old stuff used resistor wire for the power cord. I had an old radio that had a bad AC cord, but it was resistor wire so I had to add a large wirewound resistor to the inside of the chassis. It worked just fine but that wirewound resistor got so hot that I could not use it very long. I was only 9 years old at the time so I did not know about resistors with heatsinks. I guess the purpose of the resistor wire for the AC cord was to provide 6 feet of resistor allowing it to cool. All this ancient electronics gear is so fascinating. Thank you for documenting these devices in your videos.
No idea about vintage vacuum tube electronics except that they are cool!
I picked up a Waterman "Pocket Scope" S-11-A built in the late 40's at a flea market. Replaced the electrolytic caps and it runs like a champ, and appears to have original tubes. Despite it's low bandwidth, it works quite well for repairing audio gear and random analog projects. While modern test equipment is no doubt far and beyond in terms of capabilities, I don't think much of my high tech gear will last 70 years and still work. Plus, it makes a great scope clock between work tasks ;-)
Thanks for sharing your videos - I am equally entertained and fascinated while learning a few things along the way. Love your style!
Thanks for your kind comment! The Waterman scope is a great looker.
Please do open up the transformer, as I always find it interesting to see what is inside.
Just watch your vids because this has always made me want to study more into electronics.Years ago 1986 my next door neighbor asked me if I wanted all these Heath kit electronic projects he had sent in for but never put any together.The kits that he gave me were a 10" b/w television....only the audio worked on that.An am radio which I still have and works great.An oscilloscope and a voltage tester.....that worked great and I sold them through a ad in the paper years ago.And several small testing modules for like vacuum tubes.....caps....resisters.....and diodes .At the time I wanted to learn everything .....but was offered a job in learning plumbing ....in which I followed.I do enjoy your vlogs and will slowly try to get back what I learned in my youth.A friend of mine from years back taught me a lot and we were always getting supplies at Radio Shack in the late 70s/ early 80s
That's an awesome example of intentional technology. Almost 90 years old and it not only works but it's still relevant. Fantastic! Great video! Thank you.
Wonderful bit of vintage gear! I would have liked you to remove the capacitor contents from the Aerovox can and re-stuff it with the new capacitor. I think it's important to keep as much visual history of this kind of 1930s equipment so that when someone takes it apart in 50 years time they can see the kind of capacitor that was used back in the day. Leave a note in there too to show what's been done. It actually makes a good debate as to what responsibilities, if any, as restorers we actually have.
It would be pretty simple to find out if it was restored... you do NOT have to recreate the mistakes of the past to make it "real." A note would suffice.
I absolutely agree that the components need updating but if the equipment is of historical interest then leaving in place the old isolated component just to show exactly what was used originally surely gives the best of both worlds? Is the debate not more about whether a piece of equipment is historically 'worthy' of maintaining visual originality?
Exactly. The authenticity of historic equipment is destroyed by fitting modern components that are visible. At least the original component should be left so a future restorer can do it properly.
Bakelite was the first commercial plastic. It was a liquid that could be used to cast into objects or coat things like batter on a piece of chicken. It solidified into a hard, airtight material and would over time get harder and ultimately brittle if exposed to such things as ultraviolet light (many current plastics have this same problem). Very widely used in commercial and even military equipment to replace leather and glass once introduced. Created the modern "Age of Plastics".
How has this channel not got more subs? So much knowledge and wisdom, excellent teacher 👍
Seeing you depot it and relocate the caps would be a great lesson for the rest of us! That said I can understand wanting to just replace it! Cheers!
What a nice little old Beauty! Good to know it came into hands that know how to treat it and bring it back to life! Good job here!
Thanks for sharing!
Man, I'm hoping the day comes when I can say: "It doesn't have a choice, once it gets on this bench it WILL work again!" and it actually happens! I've learned a lot from you, but I feel it will still be a while yet. Cheers for the videos, Mr. C.
Even when electronics gets more capable day after day, the old stuff is fascinating!
The mains transformer _boosts_ voltage, i couldn't get used to that. The Aerovox company that made that filter condenser seems to still be around today.
Except that they now make capacitors and no more condensers.
De-pot the transformer
FHRsLP the Tar, tho. That's the secret ingredient in Kryptonite.
I'd like to see the transformer de-potting as well, even if it's just for the sake of having seen it once in my life, you never know when knowledge gets useful :)
Great video, as always. Thank you !
Yes! Depotting would indeed be another welcome opportunity to learn how to go about restoring a transformer like this back to service.
You have an infinite capacity for taking pains and doing things right. Accordingly, depotting the transformer is CLEARLY the only proper move. And along the same lines, that old 2 MFD cap looks so cool, how hard would it be to open it up, insert your new cap, and keep the vintage look? (Easy for me to say as you're the man actually doing the work.) Anyway, nice job as always.
"When its on this bench it is going to work again", Awesome
I wish I had a bench like that.
"These nice little vents are great for letting the smoke out" (2:33). Awesome 2.
It's like a Mr. Rogers version of AVE
DEPOT the transformer if it is at all reasonable, please. I enjoyed seeing the 913 tube again. It's been a really long time. I worked in the production of 6326/6198 vidicon tubes in the 1950's and we would sometimes change the coating from photoelectric to phosphorescent. This produced a 1" picture tube with amazing clarity. Very useful for "in house" test equipment similar to the one in you excellent video. Some of us adapted it for monitoring our "home made" cameras.
I have repacked some old bakelite capacitors for a Philco radio that were filled with this tar. I used a heat gun to melt it and drip out into a tin can and then pried out the old parts and desoldered connections to terminals. Final cleanup was with lighter fluid before placing modern caps inside the old bakelite container. Using the heat gun will give you more control of the process than the oven, in case something decides to ignite.
Good idea about showing how we can go around the old style transformer. I have had a couple of issues where I needed to find a replacement. I enjoy your videos. I am learning a lot.
I love old test gear. I restored my share and I can tell you what they lacked in technology they made up for in Ingenuity and cleverness. I wouldn't trade my digital equipment for old stuff, but I really enjoyed working on them and learning.
I hope you de-pot the transformer, as messy as you say it is, I think we would learn a lot about the construction, manufacturing, and theory of operation. Your channel has given me a deep appreciation for these "old-time" electronics that I've previously dismissed -- thank you for educating us
While I have never de-potted a transformer, nor do I anticipate doing so, I would really enjoy watching the process required done.
I found it! Did a little online searching and I found this exact model. Just as on the schematic, this is the Model CRM oscilloscope, made by the National Company. A little more searching resulted in finding a similar product manufactured by RCA: the Model 151. It uses the same CRT tube (913), however the RCA version has a few more functions, and RCA called it an "oscillograph."
Supreme Test Instruments also had a similar product to these two, except that the Supreme version used a 2" CRT instead of the 1" used by National and RCA.
If I am not mistaken (which I could be!), I believe the schematic of the CRM, or a generic equivalent, can be found in the 1937 ARRL Technical Manual.
Thanks for taking the time to write Erzahler!
+Mr Carlson's Lab: You are most certainly welcome, Mr. Carlson. Actually, it is I who should be thanking you, for teaching us all of this great stuff! I love the old tube gear, and I am always learning something new about it (well, new to me, anyway!), thanks to your RUclips channel. 😊👍
73 de NØJAA.
Erzahler, I used to have an early oscilloscope that used a 6U5 or 6E5 Magic Eye tube for the display, I believe it was a Dumont or RCA device as I recall. Dumont's patented Magic Eye tube was a forerunner of the CRT, and Dumont stupidly sold the technology and the patent to RCA as I recall. That technology was to eventually prove invaluable in oscilloscope and radar design , and that patent would have been worth a major fortune post World War II with the explosion of not just oscilloscopes but television.
God keep Blessing you and Yor Family ! Thanks!
Great video Paul as always. I would love to see the transformer de-potted to see if the caps can be replaced. If it ends up that its not possible to rrplace the caps then you can still replace the transformer and add the caps externally. It would be nice to see the case refurbished. Even if you are going to use it its still nice to see equipment looking its best.
Read my comment up thread, Gary, that black finish is, "Black Crackle", and modern versions of it are available, but back in the day we could make our own. I also give hints as to how cabinets and front panels could be made like new without even doing a tear down and rebuild.
I would love to see a video about depotting a transformer, maybe combine it with a video depotting old tar caps to place a modern cap inside (for full restoration)? Personally I agree with repurposing old electronics and don't make them dust gatherers but only using the guts from a 80+ years old device does kinda hurt my soul. Would rather see a device in worse condition get that treatment than this, but hey, that is my opinion. Thanks Paul for yet another neat video!
love that old caps label, It reminds me of a poster for an old circus or magic show
I love how the sine wave kinda resembles a crown being rotated in 3d space. A handy quirk of the nature of sine waves and trigonometry.
I love watching your videos , in depth details , historic items and facts , repairs and the odd Frankenstein repairs - IT’S ALIVE ! , IT’S ALIVE ! ! and the time , energy and , great effort you go through to show us all what you do through your eyes . 👍🏻🇬🇧👏🏻🇺🇸🍻🇨🇦😃🤓
I actually built one in the 80's from an article in Radio Electronics that detailed the construction. It used a 1" electrostatic CRT (I think a 1P21) and used 12AU7's for the input and deflection amps. I still have the schematic and the parts.
I'm always impressed of what kind of test gear your own from that Era. To me it looks also like some old science fiction movie equipment maybe from War of the Worlds ;) Thank you Paul for sharing this, otherwise I would never see such beauties!
Wait. Some of that stuff I used when it was considered state-of-the art.
Of course, this isn't one of them...
lol vents are nice for letting the smoke out! Always a joy watching your work
Damn you Mr. Carlson, I had things to do today. Now I have no choice but to watch this video. No choice!
LOL, I can relate. When I first found Mr. Carlsons channel, I totally went down the You Tube rabbit hole. Now, when a new vid posts, I HAVE to watch it.
Yep lets see the de-potting I am a little curious about the Cap or Caps inside and if the Potting material had a affect to why the Cap's have failed. And as always it's always a treat to hear you explain things that many others just can't seem to do well. Thanks for the great content...
Depot the transformer, it would be a really nice teaching lesson for all electronics enthusiasts. As a professional electronist, I wouldn't waste the time of doing that, and I am sure you wouldn't do that also. Given the fact that you make such great educational videos, I would recommend to do it, for all enthusiasts and hobbysts.
Great video!
Hi Paul.
Another good video, you could show both ways of dealing with the transformer as you discribed before you make a commitment on the direction you wish to take. It's just an idea you could use.
A brilliant explanation of what you are doing, keep up with the videos as I am learning lots from you.
Mr. C I think you should De-Pot the that feisty Xfmr. I have seen Ford Model T Buzz box ignitions de-tarred. The guy saved and re-used the pitch. I date from the tube age so your care and attention to detail in bringing these relics back to life is great. Remember that one hand around HV is safer than 2. Don't ask me how I know...
I love the confidence your knowledge gives you, it's on this bench so it's going to work. I wish I could be so certain and hope to expand my own knowledge. I'm glad you decided to do the depotting video
Love to see a de-potting of the transformer. I have read about it but never done one. As to the black wrinkle paint i have been there but for the twin camshaft cover on my aging Italian performance spec car. The paint was flaking off looking terrible. Removed the large alloy lump and used an alloy-friendly paint-stripper then put it through the dishwasher to totally de-oil it although it came anodized a kind of black. . The special black wrinkle paint needed a hot pre-baked part to some 200degress C so into the kitchen oven went the cover. I pulled it out an hour latter, sprayed on the paint and carefully built up the layers to cover the metal but not too thick. Then by magic it did the wrinkle thing all over. Finally, to harden it i had to return it to the kitchen oven for another hour at around 100 degress C....After that i just left it cool. Later i set a flycutter in my mill and cut just enough off the top to reveal the logo etc in shinny alloy. Back in the engine bay it looked fantastic. WARNING: using the dishwasher was OK. The stink in the kitchen was terrible and the next time i cooked a roast meal.... BLERK! it tasted of paint! (Note you can only get away with this if you are single)...
LOL, great info Pete!
Hi. I'm Mike in Jacksonville FL. Love all your projects, especially the ones involving vintage electronics, and audio circuitry.
I really enjoy working on old jukeboxs. I'd love to see a rebuild on a Rowe stereo amplifier 125watt range. Keep up the GREAT work.
Just found your channel. I am an amature radio restorer and love vids like this. I am a bit of a purist and would love to have seen you restuff that cool looking wax cap with the areovox logo
I love your attitude against "shelf queens".
I like your confidence 8-) just because of this, thumbs up.
I want one!!!! It looks like it "NEEDS" to be setting and "USED" next to my ART-13.
Just plain cool and still usable.
I’m an electronics baby, but that old green stripe scope is so cool.
When I see an old 1930’s electronic device that was used in the nascent radio industry at that time, for some funny 😄 reason, I am reminded of the scene from The Little Rascals (Our Gang) show about their “International Silver String Submarine Band” where Spanky knocks over a floor microphone and all the tubes in the radio room blow and the radio engineer pulls at his standing straight up hair. Too funny 😂
Just because it's so hard to find someone with such comprehensive knowledge, I'd like to see a depotting follow-up video.
In keeping with not labeling the front controls they did not label the external inputs. But they did do when clever bit, the horizontal inputs on the right side are arranged horizontally and the vertical input on the left side are arranged vertically. I think this was clever!
I love the Antique test equipment. Especially when it is restored and functional.It makes me think that maybe my father may have used equipment like that. He went through radio school in the 40s. I use to have his books and notes, but they were lost in the fire.
Bradley Leben yeah, so did my grandpa, was a radio op his whole life, although I doubt that this scope would have been in his classroom I like to think that he saw one sitting on the shelf as a child and that's what inspired his own career.
Wonderful device! Glad you tested the original condenser.
Very nice! I always fall asleeep watching your videos for 2 reasons:
1) I usually start watching them late in the evening
2) They tend to be long and very detailed.
And I can't wait with it until the weekend, that stuff is just too good.
This channel is so cool! I subscribed to it at some point and forgot that I had. Had not seen any new content from i in a long time. Good to be back here and learning! I love restoration of old electronic devices!
I'd really like to see a depotting of the transformer. Old tech is some kind of special and always interesting to see how certain things were done in past.
Always a pleasure to see a new upload from you. Thank You!
as a complete physics idiot i have the utmost respect for the absolute high end level of your fixes. i´ll basically watch all of your videos without any clue of what is happening. thanks for your brilliant content!!! just watching the master doing his thing gives me joy.
i wish we had somebody like you here in germany so he could fix my 2 beautiful tube echolettes from the late fifties.
Very interesting oscilloscope. Thanks for the video. I vote you plug in that toaster oven and start the bake!
I was curious about that AEROVOX condenser so I typed in the patent number (1,736,764) and found an article from 1929 detailing the process to make this paper wound paraffin wax filled cube. The patent mentions an asbestos lining used in the vat these things were made in and dielectric oils (presumably PCBs). Amazingly, the company AEROVOX is still in business making capacitors since 1922.
All the good stuff!
I note there is no lables on the switches of the capacitor tester...i guess in those days you just had to learn what they do ☺
More like in those days the engineers weren't too sure themselves. Half the stuff no one had thought of a name for it yet anyways.
they still don't. they still measure capacitors in the amount of volts per second it can randomly hold. with no mention of important stuff such as the atomic number of the materials, their area, and distance to one another. as ac and radio and light and the behaviour of capacitors are all the same thing, those aspects are far more important if we ever want to get ion drive spaceships than how many farad they just so happen to randomly hold 'it does something! let's call it a product and ship it!'
As long as it does something I'm in.
Excellent informative video Mr Carlson, very interesting to see the manufacturers design, terminology and production techniques.
" It lives ", just thinking that, when you said it.
Many thanks for sharing.
I found your channel today. I am impressed by the work you do, it is very interesting! 👍
I know it would be a lot of work but I would love seeing the de-potting procedure!
Very well done, nice piece of history. Yes love your videos and teaching.
I like to look up the history of the manufacturers (a habit from researching my late father's collection of ancient electronics). Imagine my shock at discovering Aerovox is still in business and still making capacitors! Dang! That is a rare example of staying power! Love these videos!
When my father and I did restorations we would take the old caps like that beautiful Audiovox and remove the core and repot with a modern cap so the looks are preserved...
I came across one of these via eBay. Can’t wait to see what king of test gear you plan on turning it in to!
I would love to see the transformer de-potted. Thanks Paul for this video
Mr. Carlson, I suggest de-potting the transformer. It appears to be in good condition, other than those two internal capacitors. So replacing those would keep this scope as close to original as possible.I would also suggest, placing the new filter capacitor inside the old can. Again just to be as close to original (at least in appearance) as is possible. Brendan
Good idea. Replace too much and it becomes something different
Also, it is amazing how far oscilloscopes advanced between the thirties and fifties. I've been learning about the early computers recently, and the rapid increase in the complexity of some of the signals that oscilloscopes were being used to look at during those years probably goes a long way to explain that.
Talking of which, It'd be great if you got hold of a COMDYNA or something for your old-time lab! The idea of hooking up an analog computer running a Rossler or Chua circuit to the X Y inputs of an old Marconi 'scope I have so that I can play with strange attractors is what's currently firing me up.
love watching you work on the old gear, de-pot it keep it as original as you can
It’s going to work again. It has no choice on THIS bench.
I LOVE it!
I'd definitely be interested to see it de-potted, but I'm looking forward to what you turn it into either way!
Thanks for the video! You always have the best audio quality and a very deep knowledge of your equipment that I can personally appreciate
Always cool to see the old test equipment thanks for sharing.
Thank you for this great video sir!
It is always enjoyable to see a true master of his craft at work :)
I would very much like to see the transformer de-potting as I have never done that myself & am curious about it.
But I do understand that it would be very messy & difficult so if you decide not to do that video I would still like to see the way you replace the current one..
I used to get the radios etc from 2nd ww battle ships from a small shop with a 70s version of you. They were HUGE
Cute CRT from 1935, nice art piece of ingeneering
The depot-ting process would be very nice to witness.
Would love to see a reporting, some times to save a vintage piece it's necessary, as for the paint, you can get automotive crinkle paint that is exceptional. Thoroughly enjoyed. Thanks again.
Man id love to find one of these little guys to add to my collection
This was a great video, very exciting to see that oscilloscope come back from its deep slumber. This if my first time in this channel, subscribing without a doubt. Thank you for the nice content.
Thanks, and Welcome!
The generator's back!! Awesome video, very very cool to see. I always get really excited for symmetrical round CRT display scopes!
