Hi Odium I tried to work with these microscopely small components But every time I try to pickup one with a pair of tweezers The damn thing jumps all over the place. Are you sure they are not alive. I am not so sure. Perhaps it got something to do with my hands. The bloody things won't stay in one place. Oh to be 20 again. Michel vk3kvw
hahaha i am 14 years old and i love electronics (but i am new to it) and im exactly the same i always go for old stuff like old Tektronix scopes and old radios just because i like old stuff plus its easier to repair

You've put a lot of work into this unit, and I'd love to see it in operation! Which means a proper alignment, which I'd like to see. Thank you, Paul, for all the long, hard work you put into these old units. I love seeing these venerable items realize a second life!

Agreed. If I were to guess a typenumber, I'd hazard an IN-13, as those seem to be the most widespread of these devices nowadays and has the matching 3 wires.
I remember Heath company sell Solid state tube replacements to be used in their IM-18, IM-28 and similar vtvm that uses the 12AU7 and 6AL5 vacuum tubes.
Your skills, patience and ability to explain theory and practice are simply marvelous. It is also surprising how accurate the Vedolyzer was without the touch up alignment. Well done sir...well done.
Vedolyzer alignment? You bet! Very interesting piece of equipment and nice to be able to print out the schematic. Much easier to follow along with a print out!

Been looking forward to this one, Paul. You didn't disappoint, that's a fantastic piece of gear you have, and I dare say it now runs better than the day it was built. Do keep up the in-depth videos and pay no attention to the ADHD crowd. They can always fast-forward if they get bored, but you can't put back that which wasn't there to begin with. That's what separates you from the rest of TH-cam. You put back the detail and make electronics interesting again. Congrats on another fine restoration!
Agree, but no ageism necessary. The attention deficits that humanity is facing are due, mechanically, to excessive push notifications and distractions disrupting the pathway between the anterior cingulate gyrus and anterior cingulate sulcus, as well as psychologically due to the narcissistic aspects of certain social media platforms, and neurologically manipulative advertising and marketing. It just so happens that youth are more exposed to, and ironically targeted by, such things, which are often initiated by and directly benefit certain subsets of older generations. More generally, humans have an issue where contemporary society is evolving faster than our biology can keep up, and the tendency is to throw strangers under the bus rather than work hard to improve things. It's getting to the point where drastic changes in society, or genetically engineering ourselves to have better hardware, are going to be required to avoid a scenario like the end of John B. Calhoun's 'Universe 25' experiment, except with humans instead of mice.
@@alakani I guess I'm OK. I've been living on the far side of the moon (far from what was my once home country) for most of my life, I have no FB, Twitter, or any other social media accounts, I turn off or uninstall all programs that bother me with notifications, don't do cellphone texts and watch no television. Now if I can just get rid of all advertising....
Super Heavy Duty (Carbon-Zinc) should last for a very long time, and probably a lot better than alkaline. Alkaline _will_ leak. This is why smoke detectors still list a big batch of part numbers that all point to various manufacturers SHD batteries. (very low current draw)
Perhaps that "exotic" potentiometer could be made like this: 1) Get double ganged 5k potentiometer 2) Get 470 ohm dobule or single potentiometer from same manufacturer and series 3) Take them apart and transplant one resistive element from 470 ohm pot into 5k With some care, it should work just fine. Only trick here is getting pots that can be easly taken apart and reassembled
Your perfection and explanation electronics and fixing, restoring , creation given by spirit like Tesla .keep up the good work my dear friend: Love and light to you and your family💥:
What is a vedolyzer? Who is the bad guy? Is Tom Cruise in this? I started watching part 3 this morning before I left for work. I started watching again after work and seeing the comments, I just had to laugh. I am an electronics novice and thoroughly enjoy your videos in their entirety.
Hey Paul, you had mentioned if we wanted to see you do an alignment on this piece, let you know. It would be a shame to have gone through all you have done so far and not finish it with an alignment. The cherry on top of the sundae would this alignment be! I vote for it! I’m probably not alone in that. This has been a very detailed and laborious project for you. You got some very appreciated help! Very fine video!👍🏻
Yes, I agree with most here! DO NOT SHORTEN your videos! With the awesome level of knowledge and wisdom you have teaching this stuff, it would be silly to shorten. If someone really cares and wants to learn, they will watch, and complain that a 3 hour video is too short! If not, then I'm sure they can find other stuff that is more interesting to them, to watch. 73 Michael KE4EST
It's been a few years, but I must agree. The Only thing missing here is the smell. Warm tubes, rosin, Bakelite, and the cigarettes in the ashtray, plus coffee. These are find memories of my childhood. I had a friend, a ham, that my father introduced me to. My father was an engineer, and he supported my love of electronics. This was in the late 60s. Yes. I do love watching these restorations. 73.
I definitely want to see a full alignment of this beast. I also think you challenged yourself to make an accurate graticule for the CRT. The tube is a level indicator IN-13.
Paul I'm a big fan for years. This video is great. Thanks so much for sharing your knowledge technique and skills. You have an amazing combination of Intellectual and practical/mechanical skills. My ancestry is from Montreal. At 34:51 What are "spine wires". You mentioned them a few times.
Paul, this hits me at 17:15 PM and those are great news! I watch it later in the evening, but I wonder if "Vedolyzer" can be used in the future to express the amount of effort of how an future or past restoration compares to this :) Many Thanks for sharing and doing this all for free Paul, that's an huge amount of effort!
Absolutely interested in seeing the alignment of the Vedolyzer. Excuse me, The SUPREME Vedolyzer. Every witnessed calibration increases familiarity with the process on all machines, until it becomes second-nature.
Thanks for all the interesting video's Mr. C. I love this stuff! Every time I watch you I learn at least a little something I didn't know before, or at least refreshes my memory from long ago. Love your Patreon channel too. Long video's, yes! Trivia, yes! Alignment on the Vedolyzer, yes!
Great Video Paul, thank you. The answer to your question is a nixie IN-13 :) I love nixies! I'd like to do an audio spectrum analyser whit this... Bye! :)
This is the second video in a row I've watched on TH-cam today using WD-40 as a cleaner. The prior video I watched was from Mustie1, using it to coat a bike he was working on.
Just quickly scanned the Supreme instructions on "A new system of Dynamic Analysis" (a pdf on Steve Johnson's site) which is chock full of basic instruction of radios and analysis of signals. I am sure you realize that essentially the Vedolyzer is the early precedent for the Spectrum Analyzer. You being the "Tracking Generator" you can follow the signal on the wave meter as you adjust the IF along the frequency. A step above the VTVM method of alignment. I need to thoroughly internalize this document,. I can see why you wanted this equipment working as instructional for us. Albert
I'm a Machinist I'm only 38 years old but I've been machining since I've been 7 years old. Right when cnc was considered voodoo or something that took millions of dollars of know-how to operate. It's funny how lazy and stupid a few smart people have made the masses. Yet people like Mr. Carlson keeps it old school and I respect and honer him. People lose sight of where why and how things came to be. But he knows , dam right he knows!
Hello Paul, I too will add to the congrats on another fine series of resto videos. Some constructive criticism; I would like to see you use a pointer of some kind (alignment tool?) when pointing out items on the schematic or the unit itself. And I don't think that I recall you mentioning that the Roman numeral M = 1,000. Us old geezers remember when the only Kilos were cycles! Thanks, again, for another great series and I really admire your teaching style!
Hello, I saw a very similar devices in my old reel-to-reel recorder. They were used as record level meters, and they are gas-luminescent indicators. I'm not sure how they called correctly in English, in my native language they called газонаполненные индикаторы or газосветные индикаторы.
Paul - @43:07 one of the most rewarding observations to see all of your hard work and dedication pay off. An excellent job as always and I truly appreciate the mention in the beginning of your video; my subscriber count has since jumped. Thanks again for sharing your brilliant knowledge and skills with all of us. All the best. Don
Amazing, this Vedolyzer, and its restoration. Beautifully done. Yes, would love to see the alignment procedure (and maybe a repair using it?). Those tube replacements are interesting devices too. Thanks for sharing all this!
At 5:02 I started singing, "To life, to life, I bring them, I bring all these dead men to life!" -- From the H.P. Lovecraft Historical Society's musical, _A Shoggoth on the Roof._ (Yeah, I'm weird...)
First, plaudits and many thanks for putting yourself through renovation hell and bringing back this unit from certain death and destruction. Second, ANYTHING YOU DECIDE TO DO IS OK. If something takes too long, suit yourself. I would personally enjoy seeing a complete calibration, and explanation of why you are doing whatever you are doing. de KQ2E

Excellent series on the Vedolyzer, Mr Carlson! I waited and watched the whole trilogy tonight. Your thoroughness and forethought on these electronic subjects is amazing! Very enjoyable watching a true professional at work.
Ahh. Now we learn some key reasons why this wasn’t just another typical triumph for Mr C. Not to mention just when you thought you forgot about this cliff hanger. Here it is. Posted. ? Yessir!! Now we get to watch all three to put the whole story together. Ya Paul. Looking forward to seeing this used on modern and less modern stuff. That’s one of the main mandates of your lab. Will be very cool.
What an incredible piece of equipment Mr. Carlson! Probably the first commercially successful multi-analyzer. Can't wait to see this in use on future projects both on YT and your Patreon page at your vintage workbench. Please show the alignment procedure. Very nice restoration indeed! Thank you for what you do!
Wow, thanks Paul for this 3-part video on your exhaustive restoration of this premium piece of test equipment! I have never come across this particular instrument before but, I'll bet it was the "Cat's Meow" in it's day. It's nice you were able to find some good documentation on this equipment. When I would pick up old radios/TVs at the dump in the early 1970's to bring back to life, working out of the house as a teenager, I generally had no documentation so, any fix was more of a reverse-engineering effort. I have only come across a very few old schematics during my life that used "M" for "k" on the resistor values. That's got to be very confusing for Newbies. On the vertical amplifier design, you'll notice the plate circuits are very heavily loaded with relatively low resistor values plus, some series coils. The plate resistance of pentodes is very high compared to the grid 1 and plate capacitance to ground, which very much limits high frequency response. By using the low value plate resistors, the designers were throwing away gain (swamping out the electrode capacitance) to achieve high frequency response. This is why they used so many stages of apparent amplification. By looking at the circuit values used, I suspect the bandwidth is a few MHz! Most oscilloscopes in that day had a bandwidth of 100 kHz or less. That dual-ganged variable resistor that was modified with the 2 drill holes, I wonder if that was a factory authorized service bulletin, it looked too clean for a Tech trying to hack out a quick fix. I suspect the designers opted for using the flashlight batteries for the bias supply in order to get the cleanest possible DC voltage. The drawback however: since they are using sharp cutoff pentodes, the plate current will skyrocket if the -3 volt supply drops below -2 volts. Since they don't have a way to check the battery voltage from the front panel, you could easily cook your 1852/6AC7 tubes and possibly a plate resistor. I'm not sure what the carbon/zinc battery life would be inside that chassis with all those tubes generating heat, obviously shelf life at elevated temperatures. Cool stuff, keep up the good work!
Thanks for another great informative video. I always learn something when I watch these and that's a good job done on the much anticipated completion of the Vedolyzer.
I really enjoyed this restoration. The old vintage test equipment is just sexy. I’m sure that they can make a piece of equipment that will do everything that this one could do but be the size of a transistor radio. I would rather have the vintage equipment because it connects us to the past. It’s hard to conceive that 50 years ago this month that they sent men to the moon using some vintage equipment we buy as antiques today.
Paul, you're my new hero! The attention to detail in your restorations/work are just short of phenomenal ! PLEASE keep making your videos, I'm trying to get back into electronics after leaving it back in the 80's. I never got as far into it as I wanted to back then, well, because kids and family needed fed and clothed, and there wasn't much money in it. LOL! Had to have a regular job to pay the bills. Now that I'm older, I want to get back into it. I have MUCH to learn/relearn, but some things are coming back while watching your videos. There's one thing I learned in this video especially, I DO NOT recall schematics using 'M' for 'K'. GOOD to know, thanks! :) I have some old radios I've just recently acquired to get started on, and I've purchased some test equipment. PLEASE keep up the great work and videos! :) :) When my situation gets better, I'll be jumping on Patreon for some more of your lessons. :) Thanks again! :)
Nice restoration many many man hours.I watched you fire it up ; and it was pretty close in almost all functions. This will have to get a top shelf position ,with a dedicated spot light, A true shelf Queen .. Ps: ( A little humor) Hats off, excellent work,true talent..Peace
Paul, thank you so very much for this update on the Vedolyzer! I can only imagine the frustration, pain, irritation, and aggravation you went through to bring this wonderful series of videos to us! I am sure that a lot of "off air" time working on this was filled with "Blue Blazes" , but you stuck with it and brought us a wonderful education and treat. Please do the alignment for us, it might only be a "touch up" since it is so close, but would love to know what is involved in the alignment procedure on this particular device.
What a fascinating series. I like the way you employ such neatness and make point to point wiring look like a three dimensional PCP. Looking forward to seeing it used. Cheers. Oh, yes, happy to seem more of the actual work being done if possible.
Sterling work again Mr C! You certainly pulled out the stops to get this done. What a machine, man! Cheers for making this restoration available to watch here. Btw, any chance of demoing those solid state tubes? It'd be interesting to see how they compare to the real thing :)
Absolutely amazing restoration job! First class work from start to finish. And for what it's worth, I like the long-form content - The longer the better. I guess if you're looking for the sweet spot I guess around the 1 hour mark is good, though I could happily watch this stuff all day :)
That was such an interesting and exhilarating video to watch Paul.. You're nothing short of a genius. Looking forward to the alignment of the Vedolyzer which is 10 years older than me 🤣..
Old tech is so cool. New tech is cool too, but I think we've lost a bit of something along the way. This was built to last. That is great engineering, when people really cared about their products more instead of making the next profit margin p.s. And look at the DESIGN!!! So cool!!!
I was going to joke and suggest "krytons". Hehe. No trifoil logo visible. I remember seeing these replacement devices years ago. You restored the Vedolyzer far beyond my expectations. Looks like Tektonix quality, that rebuild of the vertical amplifier is...well..supreme.
That Is a Amazing Machine, VTVM and a scope, for Aligning a radio, all in 1 machine, setting the voltage, unreal ,You don't need anything else. when aligning a radio, Great Restore, great work, Great Machine, God Bless
my dad, a hard core civil engineer, made DARN SURE that I always proceeded a decimal point with a leading zero, a k.a 0.312 rather than .312. A valuable method TODAY!
Nice! Looks like something out of " The Wizard of Oz". I was wondering if you ever get into a project where your not sure if your in too far or you're not sure if it's going to work? I've got to admire your bravery and/or determination with these projects. I'm trying myself to venture out of my comfort zone of what I can work on and you've been an inspiration! Thanks for your time making these. I've downed many gallons of ice coffee and a lot of lunches watching them.
Here is another vote for an alignment procedure video. Also, another vote for long, informative, in-depth videos. In fact, you would have even more of my interest if you decided to record and upload every minute of a repair - even the parts that you find tedious and/or boring.
There are electrical engineers that passed and maybe found a job- and there are good electrical engineers that found a job and made a diffrence for the company. I think we all know which class Mr. Carlson belongs too. That company was lucky to have his commission.
Thanks for the completion of the project. The outcome was spectacular both in terms of work quality and instrument function. I personally wont need the alignment part. However, if it eventually will be published I surely will view it. (As every single video on this channel).
i was told by an employee of textronix that every piece gets a bath when it comes in for service. soaked rinsed and dried before any service done. you are 1000% correct about the power of wd-40 it cleans connections and protects them pc ram sockets love it

The attention deficits that humanity is facing are due, mechanically, to excessive push notifications and distractions disrupting the pathway between the anterior cingulate gyrus and anterior cingulate sulcus, as well as psychologically due to the narcissistic aspects of certain social media platforms, and neurologically manipulative advertising and marketing. It just so happens that youth are more exposed to, and ironically targeted by, such things, which are often initiated by and directly benefit certain subsets of older generations. More generally, humans have an issue where contemporary society is evolving faster than our biology can keep up, and the tendency is to throw strangers under the bus rather than work hard to improve things. It's getting to the point where drastic changes in society, or genetically engineering ourselves to have better hardware, are going to be required to avoid a scenario like the end of John B. Calhoun's 'Universe 25' experiment, except with humans instead of mice.
@@alakani I guess I'm OK. I've been living on the far side of the moon (far from what was my once home country) for most of my life, I have no FB, Twitter, or any other social media accounts, I turn off or uninstall all programs that bother me with notifications, don't do cellphone texts and watch no television. Now if I can just get rid of all advertising....
@@alakani , Really? Even with a degree in Experimental Psychology, your exegesis was a bit dark for me.
beautiful piece of equipment
Super Heavy Duty (Carbon-Zinc) should last for a very long time, and probably a lot better than alkaline. Alkaline _will_ leak. This is why smoke detectors still list a big batch of part numbers that all point to various manufacturers SHD batteries. (very low current draw)
Once again this man has fantastic quality video and audio!
Perhaps that "exotic" potentiometer could be made like this:
1) Get double ganged 5k potentiometer
2) Get 470 ohm dobule or single potentiometer from same manufacturer and series
3) Take them apart and transplant one resistive element from 470 ohm pot into 5k
With some care, it should work just fine.
Only trick here is getting pots that can be easly taken apart and reassembled
There were pot kits that you could build like Lego not so long ago. Your option would be quite viable for this type of restoration.
Your perfection and explanation electronics and fixing, restoring , creation given by spirit like Tesla .keep up the good work my dear friend: Love and light to you and your family💥:
What is a vedolyzer? Who is the bad guy? Is Tom Cruise in this? I started watching part 3 this morning before I left for work. I started watching again after work and seeing the comments, I just had to laugh. I am an electronics novice and thoroughly enjoy your videos in their entirety.
The "mystery device" looks like a russian IN-13 bargraph nixie tube used for level indication.
Absolutely incredible job! Don't shy away from 3 hour videos if you can find time to film and edit them
Hey Paul, you had mentioned if we wanted to see you do an alignment on this piece, let you know. It would be a shame to have gone through all you have done so far and not finish it with an alignment. The cherry on top of the sundae would this alignment be! I vote for it! I’m probably not alone in that. This has been a very detailed and laborious project for you. You got some very appreciated help! Very fine video!👍🏻
Yes, I agree with most here! DO NOT SHORTEN your videos! With the awesome level of knowledge and wisdom you have teaching this stuff, it would be silly to shorten. If someone really cares and wants to learn, they will watch, and complain that a 3 hour video is too short! If not, then I'm sure they can find other stuff that is more interesting to them, to watch. 73 Michael KE4EST
It's been a few years, but I must agree. The Only thing missing here is the smell. Warm tubes, rosin, Bakelite, and the cigarettes in the ashtray, plus coffee.
These are find memories of my childhood. I had a friend, a ham, that my father introduced me to. My father was an engineer, and he supported my love of electronics.
This was in the late 60s. Yes.
I do love watching these restorations.
73.
I definitely want to see a full alignment of this beast. I also think you challenged yourself to make an accurate graticule for the CRT.
The tube is a level indicator IN-13.
very good video and good job done from Gary in the UK.
This a IN13 soviet nixie tube. Got 25 of them and I plan to make a very neat audio spectrum analyser
If there is a cooler looking piece of test gear out there I have never seen it.
Paul I'm a big fan for years. This video is great. Thanks so much for sharing your knowledge technique and skills. You have an amazing combination of Intellectual and practical/mechanical skills. My ancestry is from Montreal. At 34:51 What are "spine wires". You mentioned them a few times.
Hi Douglas. I said "There's fine wires." Thanks for your kind comment!
Paul, this hits me at 17:15 PM and those are great news! I watch it later in the evening, but I wonder if "Vedolyzer" can be used in the future to express the amount of effort of how an future or past restoration compares to this :) Many Thanks for sharing and doing this all for free Paul, that's an huge amount of effort!
Thank You Ralf for your kind comment!
Ralf you didn't take a guess at the "mystery item" I was willing to bet you would have I.D. it already. lol
I'd guess most projects will be the half to quarter vedolyzer range of effort, 9 months is a long time
I forgot to mention, YES PLEASE show us the allignment of this awesome vintage device :)
Absolutely interested in seeing the alignment of the Vedolyzer. Excuse me, The SUPREME Vedolyzer. Every witnessed calibration increases familiarity with the process on all machines, until it becomes second-nature.
Thanks paul. So when are you going to bring out the Interocitor rebuild video's??? ;-) Hope you have a great summer!!
Outstanding work and I really enjoyed your video. Would love to see the alignment procedure.
We should send Paul to Area 51 to get those crashed alien spacecraft working.
Thanks for the chuckle, neat idea.
You mean, to reverse engineer DARPA gravitics tech that the fools in the public think is 'alien ware' lmao.
Who says they're NOT working? Where exactly did you say you were from?
:D Sure!!!
@@davidniemi4051 I bet the aliens dont use wax caps.
Been waiting for this Mr Carlson.
Thanks for all the interesting video's Mr. C. I love this stuff! Every time I watch you I learn at least a little something I didn't know before, or at least refreshes my memory from long ago. Love your Patreon channel too. Long video's, yes! Trivia, yes! Alignment on the Vedolyzer, yes!
Hello Mr C. I really enjoyed the vedo restoration and commentary. I’d like to see an alignment.
Thank you for sharing your knowledge and skills. I have no technical background; it's your enthusiasm and rigour that holds me captive. Dee, London.
Great Video Paul, thank you. The answer to your question is a nixie IN-13 :) I love nixies! I'd like to do an audio spectrum analyser whit this... Bye! :)
This is the second video in a row I've watched on TH-cam today using WD-40 as a cleaner. The prior video I watched was from Mustie1, using it to coat a bike he was working on.
Just quickly scanned the Supreme instructions on "A new system of Dynamic Analysis" (a pdf on Steve Johnson's site) which is chock full of basic instruction of radios and analysis of signals. I am sure you realize that essentially the Vedolyzer is the early precedent for the Spectrum Analyzer. You being the "Tracking Generator" you can follow the signal on the wave meter as you adjust the IF along the frequency. A step above the VTVM method of alignment. I need to thoroughly internalize this document,. I can see why you wanted this equipment working as instructional for us. Albert
Thanks for your kind comment Albert!
The M used on this vintage schematic is based on the Roman numeral M (M = 1000).
John , Yup... but it's still a bugger of a term to interpret for many younger readers.
I'm a Machinist I'm only 38 years old but I've been machining since I've been 7 years old. Right when cnc was considered voodoo or something that took millions of dollars of know-how to operate. It's funny how lazy and stupid a few smart people have made the masses. Yet people like Mr. Carlson keeps it old school and I respect and honer him. People lose sight of where why and how things came to be. But he knows , dam right he knows!
Hello Paul,
I too will add to the congrats on another fine series of resto videos. Some constructive criticism; I would like to see you use a pointer of some kind (alignment tool?) when pointing out items on the schematic or the unit itself. And I don't think that I recall you mentioning that the Roman numeral M = 1,000. Us old geezers remember when the only Kilos were cycles!
Thanks, again, for another great series and I really admire your teaching style!
Hello,
I saw a very similar devices in my old reel-to-reel recorder. They were used as record level meters, and they are gas-luminescent indicators. I'm not sure how they called correctly in English, in my native language they called газонаполненные индикаторы or газосветные индикаторы.
Paul - @43:07 one of the most rewarding observations to see all of your hard work and dedication pay off. An excellent job as always and I truly appreciate the mention in the beginning of your video; my subscriber count has since jumped. Thanks again for sharing your brilliant knowledge and skills with all of us. All the best. Don
No Problems Don, you have a great channel!
Paul, you know that the last guy that yelled “it’s alve! It’s alive!” got killed by it’s own machine? :-) Thanks for sharing!
Amazing, this Vedolyzer, and its restoration. Beautifully done. Yes, would love to see the alignment procedure (and maybe a repair using it?). Those tube replacements are interesting devices too. Thanks for sharing all this!
That's a Soviet IN-13 Neon bargraph indicator tube.
At 5:02 I started singing,
"To life, to life, I bring them,
I bring all these dead men to life!"

(Yeah, I'm weird...)
No you're not! "Intelligent" and "Cultured" should not be confused with "Weird"! You are smart enough to know that, John!! :-)
@@jlucasound 😀
First, plaudits and many thanks for putting yourself through renovation hell and bringing back this unit from certain death and destruction. Second, ANYTHING YOU DECIDE TO DO IS OK. If something takes too long, suit yourself. I would personally enjoy seeing a complete calibration, and explanation of why you are doing whatever you are doing. de KQ2E
Agreed.
This long tube is a neon-filled gas discharge voltage indicator (Soviet IN-13??? or something similar).
Great rebuild; I do enjoy these videos very much, yours is the only channel I have ever joined the Patrion with, and that says a lot since in my ever so long life, I have been a Soldier, Police Officer (licensed in 2 States) EMT (National Registry), Carpenter, Wood worker, Business Office Manager, Gun Smith (degree), TV Repair Guy, Paralegal (Degree) Computer guy (for a small town with no service for 12 years) and general-fix-it guy most of my life.

Happy 50th Jerry!
Excellent series on the Vedolyzer, Mr Carlson! I waited and watched the whole trilogy tonight. Your thoroughness and forethought on these electronic subjects is amazing! Very enjoyable watching a true professional at work.
Ahh. Now we learn some key reasons why this wasn’t just another typical triumph for Mr C. Not to mention just when you thought you forgot about this cliff hanger.
Here it is. Posted. ? Yessir!!
Now we get to watch all three to put the whole story together.
Ya Paul. Looking forward to seeing this used on modern and less modern stuff.
That’s one of the main mandates of your lab. Will be very cool.
What an incredible piece of equipment Mr. Carlson! Probably the first commercially successful multi-analyzer. Can't wait to see this in use on future projects both on YT and your Patreon page at your vintage workbench. Please show the alignment procedure. Very nice restoration indeed! Thank you for what you do!
Wow, thanks Paul for this 3-part video on your exhaustive restoration of this premium piece of test equipment! I have never come across this particular instrument before but, I'll bet it was the "Cat's Meow" in it's day. It's nice you were able to find some good documentation on this equipment. When I would pick up old radios/TVs at the dump in the early 1970's to bring back to life, working out of the house as a teenager, I generally had no documentation so, any fix was more of a reverse-engineering effort.
I have only come across a very few old schematics during my life that used "M" for "k" on the resistor values. That's got to be very confusing for Newbies.
On the vertical amplifier design, you'll notice the plate circuits are very heavily loaded with relatively low resistor values plus, some series coils. The plate resistance of pentodes is very high compared to the grid 1 and plate capacitance to ground, which very much limits high frequency response. By using the low value plate resistors, the designers were throwing away gain (swamping out the electrode capacitance) to achieve high frequency response. This is why they used so many stages of apparent amplification. By looking at the circuit values used, I suspect the bandwidth is a few MHz! Most oscilloscopes in that day had a bandwidth of 100 kHz or less.
That dual-ganged variable resistor that was modified with the 2 drill holes, I wonder if that was a factory authorized service bulletin, it looked too clean for a Tech trying to hack out a quick fix.
I suspect the designers opted for using the flashlight batteries for the bias supply in order to get the cleanest possible DC voltage. The drawback however: since they are using sharp cutoff pentodes, the plate current will skyrocket if the -3 volt supply drops below -2 volts. Since they don't have a way to check the battery voltage from the front panel, you could easily cook your 1852/6AC7 tubes and possibly a plate resistor. I'm not sure what the carbon/zinc battery life would be inside that chassis with all those tubes generating heat, obviously shelf life at elevated temperatures. Cool stuff, keep up the good work!
Thanks for taking the time to write Bill, you know your stuff!
yes
Thanks for another great informative video. I always learn something when I watch these and that's a good job done on the much anticipated completion of the Vedolyzer.
I really enjoyed this restoration. The old vintage test equipment is just sexy. I’m sure that they can make a piece of equipment that will do everything that this one could do but be the size of a transistor radio. I would rather have the vintage equipment because it connects us to the past. It’s hard to conceive that 50 years ago this month that they sent men to the moon using some vintage equipment we buy as antiques today.
It's worth good batteries inside of A good radio then right Mr. Carlson?
Interesting that I follow you Paul and ALSO have been following Don for quite some time now. Both are excellent channels.
Paul, you're my new hero! The attention to detail in your restorations/work are just short of phenomenal ! PLEASE keep making your videos, I'm trying to get back into electronics after leaving it back in the 80's. I never got as far into it as I wanted to back then, well, because kids and family needed fed and clothed, and there wasn't much money in it. LOL! Had to have a regular job to pay the bills. Now that I'm older, I want to get back into it. I have MUCH to learn/relearn, but some things are coming back while watching your videos. There's one thing I learned in this video especially, I DO NOT recall schematics using 'M' for 'K'. GOOD to know, thanks! :) I have some old radios I've just recently acquired to get started on, and I've purchased some test equipment. PLEASE keep up the great work and videos! :) :) When my situation gets better, I'll be jumping on Patreon for some more of your lessons. :) Thanks again! :)
Nice restoration many many man hours.I watched you fire it up ; and it was pretty close in almost all functions. This will have to get a top shelf position ,with a dedicated spot light, A true shelf Queen ..
Ps: ( A little humor) Hats off, excellent work,true talent..Peace
Paul, thank you so very much for this update on the Vedolyzer! I can only imagine the frustration, pain, irritation, and aggravation you went through to bring this wonderful series of videos to us! I am sure that a lot of "off air" time working on this was filled with "Blue Blazes" , but you stuck with it and brought us a wonderful education and treat. Please do the alignment for us, it might only be a "touch up" since it is so close, but would love to know what is involved in the alignment procedure on this particular device.
What a fascinating series. I like the way you employ such neatness and make point to point wiring look like a three dimensional PCP. Looking forward to seeing it used. Cheers. Oh, yes, happy to seem more of the actual work being done if possible.
Lol at the random cap sitting on the table all alone.
Great video as always Paul
Sterling work again Mr C! You certainly pulled out the stops to get this done. What a machine, man! Cheers for making this restoration available to watch here.
Btw, any chance of demoing those solid state tubes? It'd be interesting to see how they compare to the real thing :)
Absolutely amazing restoration job! First class work from start to finish.
And for what it's worth, I like the long-form content - The longer the better. I guess if you're looking for the sweet spot I guess around the 1 hour mark is good, though I could happily watch this stuff all day :)
That was such an interesting and exhilarating video to watch Paul.. You're nothing short of a genius. Looking forward to the alignment of the Vedolyzer which is 10 years older than me 🤣..
Doesn't get much better.
Old tech is so cool. New tech is cool too, but I think we've lost a bit of something along the way. This was built to last. That is great engineering, when people really cared about their products more instead of making the next profit margin
p.s. And look at the DESIGN!!! So cool!!!
Don's channel (Restore Old Radios) is one of my favorites.
I was going to joke and suggest "krytons". Hehe. No trifoil logo visible. I remember seeing these replacement devices years ago.
You restored the Vedolyzer far beyond my expectations. Looks like Tektonix quality, that rebuild of the vertical amplifier is...well..supreme.
A bit off subject. Wasn't 'Supreme' the component supplier for the Capacitors (Sorry, Condensers) in the 1955 film 'This Island Earth'.
That Is a Amazing Machine, VTVM and a scope, for Aligning a radio, all in 1 machine, setting the voltage, unreal ,You don't need anything else. when aligning a radio, Great Restore, great work, Great Machine, God Bless
my dad, a hard core civil engineer, made DARN SURE that I always proceeded a decimal point with a leading zero, a k.a 0.312 rather than .312. A valuable method TODAY!
Nice! Looks like something out of " The Wizard of Oz". I was wondering if you ever get into a project where your not sure if your in too far or you're not sure if it's going to work? I've got to admire your bravery and/or determination with these projects. I'm trying myself to venture out of my comfort zone of what I can work on and you've been an inspiration! Thanks for your time making these. I've downed many gallons of ice coffee and a lot of lunches watching them.
Here is another vote for an alignment procedure video.
Also, another vote for long, informative, in-depth videos.
In fact, you would have even more of my interest if you decided to record and upload every minute of a repair - even the parts that you find tedious and/or boring.
There are electrical engineers that passed and maybe found a job- and there are good electrical engineers that found a job and made a diffrence for the company. I think we all know which class Mr. Carlson belongs too. That company was lucky to have his commission.
Thanks for the completion of the project. The outcome was spectacular both in terms of work quality and instrument function. I personally wont need the alignment part. However, if it eventually will be published I surely will view it. (As every single video on this channel).
Congrats on finishing the Vedolyzer! An amazing work accomplishment. I claim Don as a mentor also, second to you of course. Albert
That was great
Amazing resto Paul... what type of tube did the 'tubters' replace? thanks Tom
Absolutely love your videos, very informative and fun to watch!
i was told by an employee of textronix that every piece gets a bath when it comes in for service. soaked rinsed and dried before any service done.
you are 1000% correct about the power of wd-40 it cleans connections and protects them
pc ram sockets love it
Thanks Paul! Nice work! I wouldn't mind watching the Vedolyzer alignment. I am glad that it turned out so well!
I'd might be able to do the same, but really, it would take me ten years - and so many of my white underpants would turm brown! Bravo! Bravo!
The mystery device is a traveling wave tube or traveling wave amplifier.
