As for me it looks familiar. Very familiar to some parts for soviet s-75 system. And according to what I see in Wikipedia that system was developed in 1957.
The reason I got the tubester was because a year or so ago I commented on one of your videos if solid state versions of vacuum tubes exist and you replied telling me about them. I then went off and looked up more info on them. :)
Great! Having worked in three branches of electronics for 38 years and now aged 74 years, I still have a lot to learn. In particular, I have a couple of klystrons, apparently unused, but they are the sort without a built-in resonant cavity. It would be good to learn how to put this together even though I could likely get a few mW of microwave RF using a Gunn diode. Keep 'em coming!

You got me with the tubester. I thought it was a nuvistor. And I thought both of the little resistor-looking thingies at the end were inductors. I'm guessing the big multi-pie RF choke was used for the tower-lighting circuit in an AM station?

Just today, I was going to post how Mr. C's car is so clean and new-looking, then I thought again and changed my mind. My comment didn't have anything to do with the current post about parts identification ;-)
The 3rd item is also known as a 'varicap' diode. The number of switch positions on the switch was easy by looking at the notch-outs for the toggle lever. I'd call it a SPTT center off SW. I got everything correct at a glance except the solid-state tube substitute device. I have a couple of bags of Teledyne hermetically sealed relays in that package that led to my confusion. Back in 2012 or so I was 'the old guy in the backroom' who handled incoming surplus at a surplus electronics store who identified and priced all of the incoming surplus. But I really blew away the young guys working there when I identified a 19" rack equipment piece for them, telling them that it was the in-house built control unit for a 4 CRT vacuum pump-down cart used in the early 1970's in building C at HP in Colorado Springs as part of a 4 cart array, used to evacuate and seal oscilloscopes and HP CRT monitors, and I then described the abbreviations on the switch positions for controlling the mechanical, diffusion, cryogenic pumps, and oven controls used in the process. When a new guy at the store said, "You can't possibly know all that," I replied, "I could if I were the guy who was operating this pump-down-cart control unit at HP in Colorado Springs back in 1972."
Aww. You should share more cool stories. I would love to have the job you had in incoming. The days of the CRT are gone and people will not even know that direct write oscilloscopes are even possible soon. These days everything is filtered through digital hardware and software, always with the possibility that some nation state actor has hacked your unit and you are not seeing what is really there like the Stuxnet saga.
Just found this channel. I got my start out in electronics as a kid by trying to figure out what all those tiny components were in electronic devices. With no internet back then it took some time to get a grasp of how this stuff worked and what everything was. I enjoyed finding some component that I never saw before and hunting down what it was.
Really like your videos! I've been in the electronics industry for about 50 years and recently retired. I started out building circuits in Popular Electronics, then went to Heathkit, then original designs. Started working after school at a TV/Radio shop and doing automotive electrical stuff. Later came two way radio, random electronics repair, collecting (and repairing) old test equipment and radios. Eventual ended up working on broadcast transmitters, worked for calibration labs on and off, did pretty much everything both tube and solid state, and things to numerous to list. And it's all been fun. Even used to have a garage shop about as packed as yours... Then I got a divorce. T.T Had to get rid of 99% of everything after that - but there is a lot of fun small solid state test equipment and ham radio stuff too :-)
I live near national labs and used to spend hours in the electronics shop as a kid, just looking at old vintage stuff. I even went to an electronics shop in silicon valley that's just a warehouse. And I've never seen anything like that relay. cool. the giant choke looks just like they enlarged the little one. ha. your collection is like a museum.
#1 It's a high voltage vacuum relay. #2 It's a high current common mode choke. #3 It's a varactor diode. #4 It's a high power RF mica or ceramic capacitor. #5 It's a toggle changeover switch with four positions ( I could twll from the spherical bearing in the handle, and the notches on the collar). #6 It's a high power wire wound resistor. #7 It's a eother a op-amp, temperature controlled crystal, or a nuvistor. #8 It's a another high current and high power common mode inductor or choke, but for lower voltages (like the ones found in magnetrons) #9 It's an axial lead inductor (green), and an axial lead capacitor (brown).

My car has one such green monster in radiator fan control, bit smaller in size. There are much bigger ones out there. #9 color coded capacitors/inductors are fun to figure out, especially so when bit damaged and trying to measure them.
When I saw that large capacitor it triggered a memory. I was around 10 years old I'm 74 now and my Father was part time engineering the local radio station. The transmitter was off the air and the problem was one of those large capacitors had exploded. The station was AM and directional at night. Dad and I walked all the way out to one of the towers and borrowed a large Sangamo capacitor from the tuning unit. He installed this capacitor in the transmitter, it was a little off value and voltage rating but it worked fine on low power until a replacement came. I've made my living as an electronics technician starting out repairing television sets and retiring from the Missouri Highway Patrol as a district engineer for the communications division. Thanks for the trip down memory lane.
Well this was a fun diversion! I'd love to see this become a series. 1) Guessed correctly. 2) I was almost half right. I thought it might be a transformer of some kind. 3) I guessed it might be a diode... I guess that was technically correct, but too general to get the point. 4) I did not guess correctly. I thought it might be a massive HRC fuse. 5) Got it! I've never seen one like that though. I wonder what it was used for? 6) Got it too! 7) Nope, I thought it might be an IC or a relay. 8) Got it! 9) Got it! I guess 5/9 isn't too bad. Thanks for putting this video together!
Great video! I managed a few correct answers, which I won't bore you with. The glass device, I guessed some sort of RF amplifying device or atomic frequency standard. The mica capacitor I guessed a vacuum capacitor or high voltage surge arrestor. MY guess on the large resistor was a high-voltage fuse. My guess on Teledyne was a relay. The ferrite rod with copper winding, I guessed a common mode choke probably for emissions.
exactly - I salvaged one from a high-voltage power supply in our lab. I had to replace the other one with a completely different type, because the second hand market of the original parts is empty because of collectors who make their own stage props...
@TecKonstantin Warum wundert es mich nicht, dich hier anzutreffen? XD Du musst auch mal wieder wat aus deiner Sammlung vorführen, wenn es die Zeit erlaubt!
@uwezimmermann5427 Yup there was one of those in a Spellman HV labs power supply used to charge up capacitors in a fairly large laser I revived years ago.
I'm only 26 and I was quite surprised that I knew what I did with my limited skillset. 1: The Relay I thought was an early transistor 2: I was right with inductor but also thought it looked similar to a multi-tap transformer. 3: Didn't know it was a veractor diode but instantly thought it looked like a transistor with a broken leg (thought it was going to be a trick question) as I've never heard of them before. 4: Had no clue that was a capacitor as I didn't see where the wires connected to 😅 5: Got the 4 position switch instantly, noticed the grooves in each corner and the 4 terminals on the back 6: Saw the windings underneath the green coating so gathered that was a huge resistor. 7: Had no clue that was a modern tube replacement as I've never worked on old tube equipment, I just like seeing people restore things I'd never have a hope of fixing with my current skills with a soldering iron. That maze of things connected without PCBs is quite confusing unless I looked at it in person and had days or weeks to reverse-engineer it or by replacing things component by component until it worked again. 8: Gathered that was a choke as it looks similar to a toroidal choke with the amount of separate connections to it. 9: Got tricked by the last two, thought one was a resistor and the other was a capacitor, now I know green usually signifies an inductor. The earlier image with all those capacitors helped me to some extent but also confused me as seeing colour bands on capacitors aren't something I'm used to except on the "domino capacitors"
Bunch of my guesses: 1. A big reed relay thingie 2. Low capacitance / high voltage choke or transformer 3. Voltage reference or some 1-wire thermometer 4. RF capacitor 5. A 3-position switch 6. Big green wire-wound ceramic resistor I got under my bench somewhere 7. Quartz, SAW filter or relay 8. Big RF common-mode choke 9. Tiny evil capacitor that will make you switch it to a resistor and burn things (shango066 showed them once) and a green inductor
This was fun My Son in law's uncle who was the engineering manager of special projects at Rocketdyne. He used to bring things over for me to guess what they were. One day he showed up with krytron switch. I had only ever seen one at Sandia labs. I looked at him and said that I had only seen these used as the trigger for a nuclear weapons. He said that he used it as the igniter for the restartable rocket engines on the shuttle. I later learned that he held the patent on the ignition system.
1. Some specialised transistor 2. Big ol inducter 3. Thermister? 4. Ceramic Isolator 5. 4 position switch with 3 ons 6. Power resistor 7. Dual transistor (in a very obsolete package) 8. Also an inductor 9. Old style capacitors
It's like a pub quiz for electronics nerds. I did fairly well. 😁 I got the varicap diode wrong and the weird capacitor and inductor. Oh, and the hv relay I had no idea. Looking forward to the next quiz.
I really enjoyed this video and feel honour bound to admit that the only one I guessed was the huge capacitor. I mistook two large four-terminal inductors for transformers and for the rest I was simply hopelessly wrong. I look forward to learning more!
I got them all except for the filament choke, which I took to be a balun. The first item threw me for a moment when I saw the "50 ohm" label on it. Never heard of a "Tubester", although I knew what it was - in the UK they were called "Fetrons".
Ozzy Moses here, as soon as I learn the language Paul speaks I will rewatch the videos and learn electronomics. The first item is a Fiendish Thingy found inside the first tv remote controls and the green tube is (or will be) a Weed Pipe (mmmm ham). A Tubester is commonly known as a vacuumless-tubeless vacume tube where I live. People I know don’t know what mica is. Why does the mica capacitor say condenser? Have you seen the video where a guy explains how the Hindenburg burned/ignited? 480v= A lil’bit never hurt nobody!
I got 2 right! The inductor wound round the ferrite rod and the "tubester". Initial thought was an op amp but changed my mind because of how tall it was.
Vacuum Relais, the tuning Diode could have been an NTC or a Diac ,they exist too in this package. The Tubester let me think to a Nuvistor. The big double inductor, i thought that it was a "Transductor" German Name .( variable saturation transformer) . The big resistor ,i had no doubt. The ferrite bifilar choke, you can use also as current balun if it is the apropriate ferrite. And the green thing an inductor, but the small capacitor unknown. You have an interresting stock of components, mr C.😊
Here are my guesses as they came out of my head: 1: Some kind of transistor function device, 2: something from inside a motor, 3: Some kind of diode, 4: a huge ceramic capacitor, 5: a three way switch with 4 positions, 6: no clue, looks like a neon tube, 7: a metal covered mini tube of some kind, 8: looks like a coil out of a radio but much larger, 9: a diode, 10 (the green one): some sort of resistor.
Well, that was fun. You had me with the HV relay & I was guessing with a few others. When in school we generally called them "inductors" and were told "choke" was the old term for them but the term also applied to certain types of inductors used for filtering.
I crashed and burned on all the items shown... Pretty cool, to learn about what those are, and what they're used for.... Thanks for the teaching moments.... 🙏👍😎🇺🇲
No 1 This reminded me of a Tx/Rx cell used in some kind of RADAR system. (I wasn't far off, I knew it was a high-energy relay). No2 Giant RF -four-coil choke. Got it in one. No3 I knew it was a specialised diode, but had forgotten which - varicap (of course!). No4 Giant ceramic capacitor - I thought was a large amperage fuse... No5 4-way switch. I recognised its function immediately as it is similar in function to the 6- way 'Freeway' toggle-switch that is a replacement for the 'Switchcraft' 3-way toggles fitted to Les Paul style guitars. I have one about to be fitted to one of my guitars. No6 Big green 'dropper' resistor - I've got a few of these big ceramic jobs in my spares. No7 'Tubester' - I knew its function (replacement for thermionic valves...), just never heard it called that before. No8 Inductor - heavy duty - 'for the use of' - In this case, I knew what it was, but not what its function might be. No9 Figured the wee glass bead was a zener diode... Had no clue what the larger 'resistor lookalike' (inductor) was though.
Interesting quiz. I only really missed the first one - the 2-legged TO-92 could be one of a few things, really... I have seen Diacs, thermistors in the same package. The mini tube got me. I thought it was like a hermetically sealed transformer. Wasn't aware there were styles other than the Nuvistor. I have seen mini axial caps like that in some VHF receivers, and they were all low picofarad values as well.
#1 SPDT Vacuum relay. #2 Some kind of choke. #3 No idea. #4 No idea. #5 Center off SP3T toggle switch. #6 Power resistor. #7 No idea. #8 Choke. #9 the green one is an inductor. 5.5 out of 9!
MICA CAPACITOR TRIVIA. The Bellingham Radio/Electricity museum melted their Sanyo mica capacitors (by running their large Tesla coil for way too long. Guess it needed cooling fans.) Molten sulfur ran out! So, at least with older ones, the whole thing is embedded in that 1700s-era polymer insulator called melted sulfur. I'd seen sulfur insulators in ancient physics devices and pre-1900 antiques, but apparently it's still being used. Good idea: ...unlike epoxy and tar, when greatly overheated it won't turn into charcoal and short everything out.
I remember reading the longest running battery that drives an electrostatic bell has been going for about 100 years and is insulated with sulfur. On opening big HV mica capacitors like that I have found them potted with a very stinky waxy product. The sheets of tin and mica are very pretty.
The vacuum relay is reminiscent of the devices used in the BTtF flux capacitor. That filament choke could be repurposed as a balun. The stubby resistor lookalike capacitor was new to me. I have probably seen them before without realising they are not resistors. Lovely selection, I recon you have enough to do a few more like this. Add some traveling wave tubes triggered spark gaps for variety.
Wow..the Bots are hitting hard, I reported three of them in three minutes. I got three out of the lot, not so good identifying these parts. Nice schooling Mr. C. Thanks.
I feel slightly bad that I didn't get them all, but then I feel good that I learned a few things. Just today I pulled a 250A 3 phase inductor from a massive VFD repair and marvelled at it's abundant construction with absolutely no attempts made to cheapen it's construction, at a guess it weighed about 30kg+ and was a work of art. Happy days.
11:00 It is a Fetron. Teledyne was a famous maker of this type of devices. Part number has TS preceding the tube part number, e.g. TS12AT7. It's almost pin for pin replaceable, except that there is no filament current :)
Great format😊 I failed half at the last one (TWO) , the first i at least called a switching device, failed at the big mica, thinking it was an isolator 😂. Oh and with that tube replacement ... just called it integrated circuit ...😮 learned a bunch with fun. Oh BTW... without your channel I would probably only had the numbers of switching positions right... I want these in a smaller format for eurorack modules 😊
1) high voltage gas-filled...resistor? rectifier? nope haha 2) huge inductor choke thing... yup! 3) no idea haha 4) a ceramic fuse? nope 5) four position switch... cool! 6) huge resistor like in a 100 year old fire alarm control panel, yup! too many of these still protect buildings... 7) an early IC, or a tiny tube or relay... sort of! 8) braking resistor was all I could think of, but knew it was wrong from the ferrite 9) got both of these wrong hahaha
I found a varactor diode in a sony AV remote, that I repaired, which had it's ground connection pad ripped after the remote was stepped on. Didn't know what it was but assumed it was some type of transistor based on the shape. Reconnecting the ground with a bodge wire fixed the remote.
The second one the choke is the only one I got, but I love the new format idea. Did the silver band on the inductor near the end mean anything telltale! Vague memories of things I repaired in the 70s and haven't seen since.
I love the sp3t switch. Have you ever seen one on an instrument? What was it used for? Unlike a rotary switch or a slide switch you don't have to go through position 2 when moving from 1 to 3.
You just never know what Professor Carlson will take out of his magic hat and quiz us. I must confess I kinda got one right but I was hoping you were going to pull out the rabbit out of the hat at the end so I could get one right, but then again it would probably be a mysterious transmitter with a rabbit look...... This was great and fun.............!! Thank you!!!
Not all of us would know all the devices used in commercial electronics equipment and high powered transmitters, but the smaller components you showed near the end of the video I knew one was a choke coil and the other was a small value capacitor. I have a small collection of those kind of choke coils.
The first one is kind of famous, as in from the movie "Back to the future", with three of them in the 'Flux Capacitor'. The third I guessed as a diac, often used as a trigger for Triacs in light dimmers etc, more used to seeing varactor diodes in axial packages.

The big green resistor was used to smack Borg over the head when they would say "Resistance is Futile."
Resistance is never futile. It's voltage divided by current.
HAHAHA!

Tubesters, tubistors & fetrons! At first, I thought it was an RCA Nuvistor tuner tube, but it had too many pins!
My first guess was a micro relay. I have a bunch of almost similar relays, albeit without gold plating (which is probably they survived to date...)
I guessed an early OP-Amp.
I had some tube FM receivers that a few 7 pin tubes were replaced with short black metal capped versions, still heated up like a tube..
@@jmi5969I was assuming a relay as well because I have similar ones made by Teledyne, saw the logo
I'm only 26 and I was quite surprised that I knew what I did with my limited skillset.
1: The Relay I thought was an early transistor
2: I was right with inductor but also thought it looked similar to a multi-tap transformer.
3: Didn't know it was a veractor diode but instantly thought it looked like a transistor with a broken leg (thought it was going to be a trick question) as I've never heard of them before.
4: Had no clue that was a capacitor as I didn't see where the wires connected to 😅
5: Got the 4 position switch instantly, noticed the grooves in each corner and the 4 terminals on the back
6: Saw the windings underneath the green coating so gathered that was a huge resistor.
7: Had no clue that was a modern tube replacement as I've never worked on old tube equipment, I just like seeing people restore things I'd never have a hope of fixing with my current skills with a soldering iron. That maze of things connected without PCBs is quite confusing unless I looked at it in person and had days or weeks to reverse-engineer it or by replacing things component by component until it worked again.
8: Gathered that was a choke as it looks similar to a toroidal choke with the amount of separate connections to it.
9: Got tricked by the last two, thought one was a resistor and the other was a capacitor, now I know green usually signifies an inductor. The earlier image with all those capacitors helped me to some extent but also confused me as seeing colour bands on capacitors aren't something I'm used to except on the "domino capacitors"
You did well!
Bunch of my guesses:
1. A big reed relay thingie
2. Low capacitance / high voltage choke or transformer
3. Voltage reference or some 1-wire thermometer
4. RF capacitor
5. A 3-position switch
6. Big green wire-wound ceramic resistor I got under my bench somewhere
7. Quartz, SAW filter or relay
8. Big RF common-mode choke
9. Tiny evil capacitor that will make you switch it to a resistor and burn things (shango066 showed them once) and a green inductor
Love this video concept!
Mr Carlsons lab your RUclips videos are awesome my friend
Thank you Mr Carlson
Love your videos Mr Carlson. Keep 'em coming.
Great video Mr Carlson sir I really never seen this type of electronics very very thanks for the sharing this video sir ❤❤❤❤❤
Glad you enjoyed it
Great idea, thank you Paul. Keeps us thinking and gets the grey matter ticking over for us oldies. Pls do more such vids.... South Africa.
That was fun, I actually got a few !
This was fun
My Son in law's uncle who was the engineering manager of special projects at Rocketdyne. He used to bring things over for me to guess what they were. One day he showed up with krytron switch. I had only ever seen one at Sandia labs. I looked at him and said that I had only seen these used as the trigger for a nuclear weapons. He said that he used it as the igniter for the restartable rocket engines on the shuttle. I later learned that he held the patent on the ignition system.
Thanks for sharing your story!
Mr Carlson you’ve tapped into something really interesting here. Informative, makes the viewer do some work and most importantly.Fun….
Glad you enjoyed it
I only got 2 right... i thought for sure the last one were resistors.... The banded colors tricked me! 😅
Thank you!!
Glad you enjoyed the quiz!
I ace'd this!!!! (of course I've been in the commercial broadcast industry for over 50 years)
Nice! thanks for sharing...
1. Some specialised transistor
2. Big ol inducter
3. Thermister?
4. Ceramic Isolator
5. 4 position switch with 3 ons
6. Power resistor
7. Dual transistor (in a very obsolete package)
8. Also an inductor
9. Old style capacitors
It's like a pub quiz for electronics nerds. I did fairly well. 😁 I got the varicap diode wrong and the weird capacitor and inductor. Oh, and the hv relay I had no idea. Looking forward to the next quiz.
I really enjoyed this video and feel honour bound to admit that the only one I guessed was the huge capacitor. I mistook two large four-terminal inductors for transformers and for the rest I was simply hopelessly wrong. I look forward to learning more!
I got them all except for the filament choke, which I took to be a balun. The first item threw me for a moment when I saw the "50 ohm" label on it. Never heard of a "Tubester", although I knew what it was - in the UK they were called "Fetrons".
This was a lot of fun. I was surprised I actually got a few right! There’s some validity to learning through osmosis!
Ozzy Moses here, as soon as I learn the language Paul speaks I will rewatch the videos and learn electronomics. The first item is a Fiendish Thingy found inside the first tv remote controls and the green tube is (or will be) a Weed Pipe (mmmm ham). A Tubester is commonly known as a vacuumless-tubeless vacume tube where I live. People I know don’t know what mica is. Why does the mica capacitor say condenser? Have you seen the video where a guy explains how the Hindenburg burned/ignited?
480v= A lil’bit never hurt nobody!
Paul, that was fun, I actually have most of those parts, however I missed on the green inductor!! Cheers and 73
The switch is automotive. Cole-Hursee is the stamped logo. One of those switch positions is likely a combination of the other two. Center off.
It had 4 connections where one is in the center. Looked like common to 1, common to 2 or common to 3, with middle position off.
I got 2 right! The inductor wound round the ferrite rod and the "tubester". Initial thought was an op amp but changed my mind because of how tall it was.
Got a few but great to learn about all of them great video very informative
Vacuum Relais, the tuning Diode could have been an NTC or a Diac ,they exist too in this package. The Tubester let me think to a Nuvistor. The big double inductor, i thought that it was a "Transductor" German Name .( variable saturation transformer) . The big resistor ,i had no doubt. The ferrite bifilar choke, you can use also as current balun if it is the apropriate ferrite. And the green thing an inductor, but the small capacitor unknown. You have an interresting stock of components, mr C.😊
Here are my guesses as they came out of my head: 1: Some kind of transistor function device, 2: something from inside a motor, 3: Some kind of diode, 4: a huge ceramic capacitor, 5: a three way switch with 4 positions, 6: no clue, looks like a neon tube, 7: a metal covered mini tube of some kind, 8: looks like a coil out of a radio but much larger, 9: a diode, 10 (the green one): some sort of resistor.
Well, that was fun. You had me with the HV relay & I was guessing with a few others. When in school we generally called them "inductors" and were told "choke" was the old term for them but the term also applied to certain types of inductors used for filtering.
That vacuum relay remember me the antenna relay of ART-13. Amazing construction.
I crashed and burned on all the items shown...
Pretty cool, to learn about what those are, and what they're used for....
Thanks for the teaching moments....
🙏👍😎🇺🇲
Glad you enjoyed!
The 1st one is a flux capacitor! 😂
Thanks Paul. Lots of fun!
No 1 This reminded me of a Tx/Rx cell used in some kind of RADAR system. (I wasn't far off, I knew it was a high-energy relay).
No2 Giant RF -four-coil choke. Got it in one.
No3 I knew it was a specialised diode, but had forgotten which - varicap (of course!).
No4 Giant ceramic capacitor - I thought was a large amperage fuse...
No5 4-way switch. I recognised its function immediately as it is similar in function to the 6- way 'Freeway' toggle-switch that is a replacement for the 'Switchcraft' 3-way toggles fitted to Les Paul style guitars. I have one about to be fitted to one of my guitars.
No6 Big green 'dropper' resistor - I've got a few of these big ceramic jobs in my spares.
No7 'Tubester' - I knew its function (replacement for thermionic valves...), just never heard it called that before.
No8 Inductor - heavy duty - 'for the use of' - In this case, I knew what it was, but not what its function might be.
No9 Figured the wee glass bead was a zener diode... Had no clue what the larger 'resistor lookalike' (inductor) was though.
Interesting quiz. I only really missed the first one - the 2-legged TO-92 could be one of a few things, really... I have seen Diacs, thermistors in the same package. The mini tube got me. I thought it was like a hermetically sealed transformer. Wasn't aware there were styles other than the Nuvistor. I have seen mini axial caps like that in some VHF receivers, and they were all low picofarad values as well.
Very informative and fun. Thanks
#1 SPDT Vacuum relay. #2 Some kind of choke. #3 No idea. #4 No idea. #5 Center off SP3T toggle switch. #6 Power resistor. #7 No idea. #8 Choke. #9 the green one is an inductor.
5.5 out of 9!
cool, great video, show us more!!! mike
MICA CAPACITOR TRIVIA. The Bellingham Radio/Electricity museum melted their Sanyo mica capacitors (by running their large Tesla coil for way too long. Guess it needed cooling fans.) Molten sulfur ran out! So, at least with older ones, the whole thing is embedded in that 1700s-era polymer insulator called melted sulfur. I'd seen sulfur insulators in ancient physics devices and pre-1900 antiques, but apparently it's still being used. Good idea: ...unlike epoxy and tar, when greatly overheated it won't turn into charcoal and short everything out.
They usually ooze tar when over heated.
@@MrCarlsonsLab And they smell good, too. I could always tell by the smell when one was getting ready to let go.
I remember reading the longest running battery that drives an electrostatic bell has been going for about 100 years and is insulated with sulfur.
On opening big HV mica capacitors like that I have found them potted with a very stinky waxy product. The sheets of tin and mica are very pretty.
100%, thank you very nuch.
You're welcome!
This was excellent Paul. 73 OM
Interesting quiz. i got everything except the big mica capacitor and the little tubester. I almost didn't get the little capacitor at the end
This was really cool 👏👍
The vacuum relay is reminiscent of the devices used in the BTtF flux capacitor.
That filament choke could be repurposed as a balun.
The stubby resistor lookalike capacitor was new to me. I have probably seen them before without realising they are not resistors.
Lovely selection, I recon you have enough to do a few more like this. Add some traveling wave tubes triggered spark gaps for variety.
Thumbs up cool video,agreed on that 4 position switch, or that big relay in the glass tubes
Wow..the Bots are hitting hard, I reported three of them in three minutes. I got three out of the lot, not so good identifying these parts. Nice schooling Mr. C. Thanks.
Thanks😊
I feel slightly bad that I didn't get them all, but then I feel good that I learned a few things. Just today I pulled a 250A 3 phase inductor from a massive VFD repair and marvelled at it's
abundant construction with absolutely no attempts made to cheapen it's construction, at a guess it weighed about 30kg+ and was a work of art. Happy days.
the varactor diode has the same look as a diac. 32v bi-directional diode. TEK 7K switching supplies used to use them for a startup pulse.
I got the Mica capacitor turned paperweight right -no... just kidding LOL but was fun to try and figure out. Wow your electronic knowledge is amazing!
11:00 It is a Fetron. Teledyne was a famous maker of this type of devices. Part number has TS preceding the tube part number, e.g. TS12AT7. It's almost pin for pin replaceable, except that there is no filament current :)
01:00 That is most certainly a relay from an Interocitor .....
As seen in the film " This Island Earth "
Great format😊 I failed half at the last one (TWO) , the first i at least called a switching device, failed at the big mica, thinking it was an isolator 😂. Oh and with that tube replacement ... just called it integrated circuit ...😮 learned a bunch with fun.
Oh BTW... without your channel I would probably only had the numbers of switching positions right... I want these in a smaller format for eurorack modules 😊
1) high voltage gas-filled...resistor? rectifier? nope haha
2) huge inductor choke thing... yup!
3) no idea haha
4) a ceramic fuse? nope
5) four position switch... cool!
6) huge resistor like in a 100 year old fire alarm control panel, yup! too many of these still protect buildings...
7) an early IC, or a tiny tube or relay... sort of!
8) braking resistor was all I could think of, but knew it was wrong from the ferrite
9) got both of these wrong hahaha
10:44 I got the cap for transmitters and the filament choke. I used to work with broadcast transmitters. Also, the very high watt resistor.
Fun idea for a video. Very cool
I found a varactor diode in a sony AV remote, that I repaired, which had it's ground connection pad ripped after the remote was stepped on. Didn't know what it was but assumed it was some type of transistor based on the shape. Reconnecting the ground with a bodge wire fixed the remote.
The second one the choke is the only one I got, but I love the new format idea.
Did the silver band on the inductor near the end mean anything telltale! Vague memories of things I repaired in the 70s and haven't seen since.
Let's just say that I need to watch more of your videos (and I've even watched a lot!) 😂
Got the categories right! Missed most of the details though. 😅👍
This was fun! I actually had a few correct. Some of it looked like something out the Borg cabinet of horrors.
Thanks for playing along!
I love the sp3t switch. Have you ever seen one on an instrument? What was it used for? Unlike a rotary switch or a slide switch you don't have to go through position 2 when moving from 1 to 3.
You just never know what Professor Carlson will take out of his magic hat and quiz us. I must confess I kinda got one right but I was hoping you were going to pull out the rabbit out of the hat at the end so I could get one right, but then again it would probably be a mysterious transmitter with a rabbit look...... This was great and fun.............!! Thank you!!!
Not all of us would know all the devices used in commercial electronics equipment and high powered transmitters, but the smaller components you showed near the end of the video I knew one was a choke coil and the other was a small value capacitor. I have a small collection of those kind of choke coils.
7 for 9. I whiffed on the relay (should have known that one), and ID'ed the varactor as a temperature sensor.
I got half of those correct.
Yes… BIG is the word for THAT mica capacitor!!! 😂
First time I’ve ever seen a filament choke!
Hello Paul - was correct with all the components until the last one I thought they were both inductors.
I think I will finaly have to invest into a patreon. Just to anticing and good for a ham that likes to try to repair old trxs
The first one is kind of famous, as in from the movie "Back to the future", with three of them in the 'Flux Capacitor'.
The third I guessed as a diac, often used as a trigger for Triacs in light dimmers etc, more used to seeing varactor diodes in axial packages.
I was way off on the HV relay, I thought it was some kind of particle sensor. The tubester is new to me also.
Excellent
At first, I thought it was a surge arrestor. The HV relay performs much like a reed relay.
Very cool, Mr. C!
Vacuum tube with three electrodes. has a big ring on it that has connections, most likely a coil. Probably a high voltage relay
High voltage relay. Seen these in rather old antenns switches and in older laser stuff.❤
I feel good for having gotten 2 or 3 of these!
