i am unsure, but within the klystrons, there may have been the type that acted as the high speed switch that sequence the firing of the first atomic bomb.
Thanks for the virtual tour. Wonderful collection. I pray your collection is passed on to a museum so future generations can appreciate this technology . I worked at a Westinghouse vacuum tube facility in the 80’s, where I experienced first hand the assembly of such tubes. People don’t realize what is involved making such tubes, Ron you make it look too easy. Most people have never seen a glass lathe, vac-ion pump, getter flasher, aging rack , etc. Thank you for preserving this piece of history.f I love sharing this old and new technology, most of my colleagues have passed and their skill and knowledge has gone with them. I wish you were my neighbor.
There's a UA-cam channel called Signal Ditch where the guy is doing a lot of research into buying parts for making vacuum tubes and building his own vacuum lathe.
When I was a little kid the neighbor threw out an old TV set - I took it home and then took it apart and found all these tubes inside. Along with the TV was an RCA Receiving Tube Manual. The TV itself was a Heathkit. I started building Tube circuits when I was 12. Good times!
Simply amazing... well done to all who were involved. In time, I hope a national museum will be interested enough to take over stewardship of this unique collection of historical artefacts.
I am tube collector from Ukraine. One of the biggest (or biggest?) private tube and ionic devices collection in the country. Collected over 30 years. But it is just in boxes, no time to describe it in database, looking as warehouse, not so nice like yours )
Sorry your country is being trashed! We here in the USA don't agree with what is going on. Not one thing we can do about it. The USA governmnet is a separate evil entity unto itself and does whatever suits it!
OMG!!! I have now seen heaven. Pull up a chair, pull a vacuum, and prepare to have your mind absolutely blown. Please do not fail to put one interrupted hour aside and watch all of this unique presentation of the world-class collection. All hail the Glasslinger! Socket to me, and thanks for this outstanding video.
Amazing collection! Regarding semiconductors and availability, my rule of thumb is that if you can see it without a magnifying glass then it probably isn’t available these days.
My buddy, Geoff, reckons he has 250,000 vacuum tubes for stereo gear. But he's not entirely sure, because he has been collecting them for three decades without documenting his collection properly. I think he also has 70+ cars. Crazy stuff!
This is absolutely FASCINATING! What an amazing assortment. I'm elated that you are still making videos, and wish you good health. Keep up the great work!
I love that you got all these weird tubes documenting the full history of tubes, I don't even know what half of your tubes are used for. My collection is mostly various types of audio and radio tubes.
Hi Ron. So nice to see a new upload from you. I can stop worrying about you! I will enjoy this video in the morning with my coffe. Stay safe and best wishes to you and the pussycat. xxxx
That Soviet tube ФЭУ-2 seen at 3:58 is a single cascade photomultiplier with antimony-cesium photocathode. It was widely used in film equipment audio amplifiers as audio track photodetector and in different measuring and control units.
I have one of these in my 1956 Lomo Kinap Cinema amplifier. It sits inside of an opening in the amplifier. The opening can be closed off with a metal shutter. It appears that the projector would have originally been designed to sit on top of the amp and the film reel run past this window. I dont understand what the job of the tube would be in relation to the film reel though. Can you explain? does the film reel contain audio content too? Or does it send a signal to the amp to turn on/off at the correct moments? Would love to understand more!
That's a fabulous tube collection. Some of those I've only seen pictures of in old Basic Electronics books from like the 60's. It's fantastic to see them for real.
At 6:24, the transistor at the far right with the red-green-violet dots is a Bell Labs 1752, the first junction transistor from around 1951, and very rare! I've wanted one of those for my collection for a long time!
u have a very large collection PLEASE make arrangements for the collection when we pass on so others can continue to see such things , I am going to off load hundreds of tubes from my many decades of collecting here near Lismore nsw for free to collectors in the very near , all the best Ron we have a passion for these things !!
I am the inheritor of this collection, saving it from the 4 winds as the previous owner passes on. I will certainly find someone to take on the collection when I get feeble.
Fascinating! That German multi-element tube at 31:00 is the original integrated circuit! With an integrated detector and audio amplifier, It did more than Robert Noyce's solid state IC invention in 1958.
Ruddy hell Ron, so tats what you’ve been up to for the last 5 months😂. And I bet you have a load more in boxes in another room.. new old stock! But really, that must the most comprehensive tube collection in the world.
Much of those can be appreciated as art pieces, even if they don't work. I work often with guitar amps, so those tubes are more common types. Thanks for sharing.
Would love a more detailed description and lesson and history on each of the tube types. Especially the various microwave tube. Traveling wave, klystron, etc. Will you consider making such video series Ron? Please!
When the Sun finally hits us with the big solar storm and annihilates our semiconductor universe, we'll know who to come to save us. The actual instructions for making tubes will probably be lost, but these examples could resurrect an industry. Impressive collection.
Interesting ---- was that the eye tube with the almost white luminous target? I have some new old stock RCA 6E5 and 6U5, and even when unused the target is a light gray color (coated with a mineral called willemite).
Wow what a varied collection of tubes! My mother worked at G.E. Bridgeport Connecticut during WW2! She assembled radios and Radar sets for the Army Airforce (B29) bomber and she also worked on assembling the remote control analog computer that operated the remote gunnery control systems. She often talked about working with those "Pencil tubes" which was a "TOP SECRET" development back then during WW2.
Thank you Ron, for sharing with usyour most valuable treasures: your tubes collection and your huge knowledge. Nice, rare and beautiful. Sadly, it is not open to the public. Maybe one day...
Wow! When I started watching, I didn't think I would watch much of it, but I couldn't stop. Watched all of it, with detours to Google for such things as Acorn tubes and the histories of Raytheon and Marconi. Well done, Glasslinger, you are a treasure.
The mounting setup for displaying these tubes did seem like it required a bit more work and a *lot more* hardware (threaded standoffs, wingnuts, and rare/expensive tube sockets) than necessary. Granted, it's not a true museum display; but my OCD and retentive personality would have me orienting all of the tubes in such a way that you could see the labels and as much of the plate structure as possible. But that's just me....
Really cool collection!! If you need some EU tube sockets, let me know. I often go from US and EU and back! 😊 I am actually very curious about that loudspeaker collection as well!!
03:57 - ФЭУ-2 is simple photomultiplier tube. For example, it was used in soviet cinema projector sound amplifier КУУП-56 to 'read' sound from special track on film.
So pleased to see you back again. I always, always and always learn so much from you. It is every time a delight and sometimes a wonder to see you work. Volkmaar
long ago i worked with equipment that had photoelectric tubes about 3 or 4 inches diameter and over a foot long. they were really rare. an audit was once made of all of them in the world because they cost about $14,000 each. the audit turned up one short...it had been sent to the moon. i don't know what it was used for on the moon.
And I thought I have had every tube pass through my hands over the years, Not a Chance. My dad was a TV radio repair guy in the 50-60s, I took up guitar amps in the '60s, and we had thousands of tubes NOS I sold tubes locally and on eBay then down to HiFi Guitar Tubes until 2018. Losing my vision put an end to my hobby. I do have a display of 12 unique tubes still on a shelf. BTW we are a Odd Lot and I am OK with that, Haha
Wow you have an amazing collection I'm truly jealous. If you had tags with short descriptions on each one this display would easily be worthy of the museum.
I worked 47 years at Varian & Eimac. Later changed to CPI. As quality assurance. Some you have seen my QA stamp on the reflex klystrons. Major playing of the voyager 1 & 2 for JPI. Medical too. I retired a few years ago in Palo Alto.
This was absolutely fascinating! I remember some of those tubes from work. I think the photomultiplier tube you said was from a CT was actually used in the Picker 600 CT scanner. It was built in Cleveland Ohio at the Picker Miner Road plant. Although I never worked on one, I did do a little service on the model 1200 that came after it. Each tube had to be individually calibrated, and there were 100's of them! I also remember the large PMT's from the nuclear gamma cameras. Those were also a lot of work to peak each of them. As soon as you adjusted one, all the adjacent tubes would go out of alignment! What a job! I still have some of those tubes in the warehouse someplace. Thanks so much for sharing!!
That’s a FANTASTIC vacuum tube collection. Just keep all these away from moisture, condensation, and water 💧, or they’ll go to air. That’s a very INTERESTING 🤨 vacuum tube collection. Your friend, Jeff.
@@goodun2974 That’s what I meant. There’s too many 👨 dual purpose sayings in the world 🌎. The same exact sentence can mean 😪 two completely different things. Your friend, Jeff.
All those amazing tube's. I was just wondering if you were ok the other day, Ron. I was taking off radio knobs using your little trick and reminded myself that I hadn't seen you for a while.
This is awesome! I hope the collection will some day show up in a public location. It appears some tubes are duds while others look perfectly functional. I think it would be cool to put some of the working units on the bench and warm them up.
Nice job Ron. I never thought I would do what you have done with those old glass vacuum tubes you have. Keep adding them to your collection, they are part of history.
The Russian vacuum tube (4:06) is a photomultiplier tube. Antimony-cesium photocathode. Number of amplification stages 1. Used in various equipment for automation and decoupling of electrical signals. This device is still available for purchase. Digressing from this, I note that I admire your art, including glassblowing and craftsmanship in general.
I am already amazed. Your knowledge is remarkable. I might like a schematic of your tube testing power supply. Followed you for some years now. I am in New Brunswick Canada but still might visit. Nobody here is much interested.@@glasslinger
20:56 - that looks like a GMI5, a soviet pulse modulator tetrode. There's also a bigger version called GMI7. These tubes have gigantic cathodes and can switch the high voltage for the magnetron inside a radar transmitter directly, giving more control over the pulse duration than the classic circuit based on a thyratron + charged delay line. I don't know the pulse current for the GMI5, but for the GMI7 its around 80A, at a maximum anode voltage of 20kV or so. If you search for "GMI7 radar modulator MIG", you can find pictures of the radar transmitter of a MIG fighter jet, with a GMI7 inside a big pressurized cast aluminum case.
80A - this is an absolute cathode emission capability. New GMI-7 (or GMI-7-1) has a peak pulse anode current around 50A, but due to the high PRF in pulse modulator and magnetron current, it rarely exceeds 15-22 А with 0.5-1 uS pulse width. The anode voltage is also set to about 80% of peak datasheet value to reduce sparking ratio per day. GMI-5 has a peak anode current ab 35A, usually working with 10-12A and 7-14 kV plate. As common, the most frequently used magnetrons are MI-296/MI-268 with GMI-5 and MI-189/MI-521B-2 with GMI-7. I`ve worked with these tubes and can say that they are very good and reliable.
@@Magic_Tee Thanks for all the additional information, especially the practical operating conditions. About 20 years ago I built a very simple radar transceiver using a microwave oven magnetron. For this project I researched the various methods of pulsing the magnetron and came across the range of Russian modulator tubes such as the GMI7, GMI5, GMI83-V. The ridiculous voltages and currents totally fascinated me. After removing the EMI filter in the heater supply box of a normal microwave oven magnetron I was able to get clean 1.5kW pulses as short as 300ns using the GMI83V to switch a -5,5kV supply into the magnetron's cathode. As a grid driver I used a Mosfet that was driven by an Atmel ATTiny2313 running a simple assembler program. The grid driver mosfet pulsed about 100V into a wide band ferrite transformer, the secondary of which was connected to the grid. I remember that i needed to bias the tube somewhere below -200V to get it completely cut off. The average HT power consumption at a PRF of 500Hz was low enough that the ignition transformer of an old oil furnace was sufficient. As a receiver I used a modified analog TV wireless link. Display was just an Oscilloscope, range was around 25-30km against Airliners (A-320, 767 etc.). Obviously not recommended to replicate this project at all, even though it was in the ISM band and thus not a completely forbidden frequency. When I had the first 3-4 screenshots of aircraft echos, the whole thing got disassembled and never turned on again. The modulator chassis and the modified magnetron are still around in some cardboard box in the basement...
@@tpa6120a2dwp An oven magnetron is far from the best choice for pulsed operation, but I'm glad to hear that you have built a modulator pulser - it can be very complicated, with apparent simplicity and sometimes too tough for nowadays low-voltage oriented "engineers". GMI-83 is also a great tube, but was copied from the 715-C tube, which can be seen in this video. As well as GMI-83V. On the contrary, GMI-5 and GMI-7 is an original and very successful design in the range below 30 kV.
@@Magic_Tee My choice of an oven magnetron for the project was more or less mainly that I could not find anything on the internet at that time that somebody had tried it before. Also, this strange world of high voltages, currents and fast pulses was fascinating in itself for me, I had never worked with anything like that before. So this was more of an experiment on whether it can be done at all and what kind of performance can be obtained. From a technical standpoint, there are two additional reasons: the voltages and currents required are low compared to a real, proper pulse magnetron, thus making it a "low hanging fruit" to try as first experiment. In a microwave oven, the magnetron is generally run in a single pulse rectifier doubler circuit, i.e. when the label on the back says the oven has a power of say 700W, the magnetron actually only runs every other half wave, so the power is about 1500W for 8ms or so, then the magnetron is off for 12ms until the next 50Hz cycle comes. In the time the magnetron does not oscillate, the capacitor of the doubler is charged. So, effectively its a 1500W magnetron running at 40%ish duty cycle. The voltage and current when it runs was 4.5kV and about 0.6A in my case. Another important reason was that the frequency is in the ISM Band where there are plenty of industrial applications where some of the RF always escapes, so me goofing around with a puny 1.5kW at 2.45GHz would maybe cause some bad WiFi in the vicinity but otherwise go ideally unnoticed. Regarding the GMI83 and GMI83V, I found that all the GMI83 (the 715-C clone) that I purchased had drawn a little bit of air and were defective. The GMI83V on the other hand were all in perfect condition, I absolutely agree those tubes are excellent quality, very easy to work with. I also tried using the GI-30 in the modulator, but this was less stable - I noticed a weird pulse length jitter that I could not find the origin of. Also, the magnetron appeared to jump between oscillation modes during the pulse which could be observed on an oscilloscope connected to a RF power detector. At that time I also had access to an old HP5372A modulation analyzer, so I took some measurements of what the frequency was doing during the pulses. With the GMI83V there was a lot less FM on the pulse compared to the GI-30.
@@tpa6120a2dwp Ah, now it’s clear what was required from the system. Nowadays this of course can be done in a much easier way, with FET/IGBT Between cathode and ground, with a storage capacitor. BTW, the oven magnetron can be forced a lot by changing magnets with stronger one - with boosting anode voltage it can give up to 2 kW with proper cooling. On the other hand, I meant something different about pulse mode running, saying closer to classical 0.3-2uS pulse width with voltages of 10+ kV - they can give some pulse output, light up a neon bulb or so, but their cathodes cant produce same current density as indirect heating oxide (especially on high PRF and D-cycle), so the peak pulse power as a peak-factor is pretty low. Besides that, at short pumps (like 1 uS or so) they start to oscillate in floating mode (jumping from normal п-mode to the high order electric field-patterns and back), which also increases power drops to the output. And finally, due to the Child-Langmuir law, a specific effect occurs when the anode current does not increase and even drops above a certain voltage value due to the "dip" potential near the cathode ("reflecting" electron-cloud near it). So, something like that. As for GI-30 it`s difficult to predict it behavior in modulator switching - originally, this tube type (which translates as "oscillation pulsed - генераторная импульсная) was design to work with coax UHF/VHF high power oscillator or amplifier with grounded grid. Especially big versions like GI-19 or GI-7B and others. But I`ve seen GI-30 in vintage pulse modulators as part of "clocking-blocking" oscillator for driving a bigger hard-switch tube like GMI-90.
My father's first hearing aid had two very small tubes, like the one at the top row, 10th from the left on the black board at 2:20 . . . and a HUGE battery in a separate container with a shoulder strap.
I am from California. I have cleaned up a mess from many earthquakes. Even a small quake, like a 3.5, would knock all of those to the ground. I think some kind of barrier should be installed to keep this collection safe.
I live in Houston TX about 50 miles from the gulf of mexico. It is a mud flat! No earthquakes here at all. But we do get an occasional hurricane! My house has been here for right at 70 years. Not worried!
Hey Ron your tech friend Dave here your video was amazing it was nice seeing all those tubes thank you you have a nice collection it was a long cold winter and I missed your videos I have a lot of tubes in radios myself retired hope to see another one of your videos soon may God bless you and keep you safe always your friend day thank you

This was absolutely fascinating! I remember some of those tubes from work. I think the photomultiplier tube you said was from a CT was actually used in the Picker 600 CT scanner. It was built in Cleveland Ohio at the Picker Miner Road plant. Although I never worked on one, I did do a little service on the model 1200 that came after it. Each tube had to be individually calibrated, and there were 100's of them! I also remember the large PMT's from the nuclear gamma cameras. Those were also a lot of work to peak each of them. As soon as you adjusted one, all the adjacent tubes would go out of alignment! What a job! I still have some of those tubes in the warehouse someplace. Thanks so much for sharing!!
That’s a FANTASTIC vacuum tube collection. Just keep all these away from moisture, condensation, and water 💧, or they’ll go to air. That’s a very INTERESTING 🤨 vacuum tube collection. Your friend, Jeff.
Vacuum tubes don't "go to air"; air goes to (into) the vacuum tube, if the seal fails....
@@goodun2974 That’s what I meant. There’s too many 👨 dual purpose sayings in the world 🌎. The same exact sentence can mean 😪 two completely different things. Your friend, Jeff.
Thanks for all your sharing ❤
Your videos is always incredible
A hobby is a hobby, no matter how quaint.
Hi Good to see you back wow what a collection there's enough parts there to build a radio transmitter
Thank you so much for sharing this!
Thank you , impressive collection !
❤😊 Excellent! 👍 I have around 600 vacuum tubes.
at 04:00 ФЭУ-2 (FEU-2) is kind of a photo multiplier tube used in film projectors so reproduce the optically saved sound
All those amazing tube's. I was just wondering if you were ok the other day, Ron. I was taking off radio knobs using your little trick and reminded myself that I hadn't seen you for a while.
ФЭУ-2 This is an ancient photodiode that read the sound from the film from the sound track. Used in film projectors.
Thanks Ron , at least we know that you are healthy. You should add a Crookes tube !
I have missed your videos! Glad your back! Those old tubes bring back good memories. Thanx Ken from gpt ms
This is awesome! I hope the collection will some day show up in a public location. It appears some tubes are duds while others look perfectly functional. I think it would be cool to put some of the working units on the bench and warm them up.
Nice job Ron. I never thought I would do what you have done with those old glass vacuum tubes you have. Keep adding them to your collection, they are part of history.
The Russian vacuum tube (4:06) is a photomultiplier tube. Antimony-cesium photocathode. Number of amplification stages 1. Used in various equipment for automation and decoupling of electrical signals. This device is still available for purchase. Digressing from this, I note that I admire your art, including glassblowing and craftsmanship in general.
Thanks Ron for showing us your collection. I need to take mine out of the boxes and put them on display.
Ron that's just incredible!
Thank you for sharing. Tubes keep amazing me, being of the solid state generation.
You are just amazing Ron. I wish I could visit you and your museum. You are such a genius.
If you are ever in Houston drop by! I show the collection off often! Just had someone today. He was totally amazed!
I am already amazed. Your knowledge is remarkable. I might like a schematic of your tube testing power supply. Followed you for some years now. I am in New Brunswick Canada but still might visit. Nobody here is much interested.@@glasslinger
Какая богатая историческая коллекция радиоламп! Есть даже лампы и трубки Гейгера из СССР! Thank you for contemplating such beauty!
You never cease to amaze with your collection. Wow 👍👍👍👍👍👍👍👍👍👍
20:56 - that looks like a GMI5, a soviet pulse modulator tetrode. There's also a bigger version called GMI7. These tubes have gigantic cathodes and can switch the high voltage for the magnetron inside a radar transmitter directly, giving more control over the pulse duration than the classic circuit based on a thyratron + charged delay line. I don't know the pulse current for the GMI5, but for the GMI7 its around 80A, at a maximum anode voltage of 20kV or so. If you search for "GMI7 radar modulator MIG", you can find pictures of the radar transmitter of a MIG fighter jet, with a GMI7 inside a big pressurized cast aluminum case.
80A - this is an absolute cathode emission capability. New GMI-7 (or GMI-7-1) has a peak pulse anode current around 50A, but due to the high PRF in pulse modulator and magnetron current, it rarely exceeds 15-22 А with 0.5-1 uS pulse width. The anode voltage is also set to about 80% of peak datasheet value to reduce sparking ratio per day. GMI-5 has a peak anode current ab 35A, usually working with 10-12A and 7-14 kV plate. As common, the most frequently used magnetrons are MI-296/MI-268 with GMI-5 and MI-189/MI-521B-2 with GMI-7.
I`ve worked with these tubes and can say that they are very good and reliable.
@@Magic_Tee Thanks for all the additional information, especially the practical operating conditions. About 20 years ago I built a very simple radar transceiver using a microwave oven magnetron. For this project I researched the various methods of pulsing the magnetron and came across the range of Russian modulator tubes such as the GMI7, GMI5, GMI83-V. The ridiculous voltages and currents totally fascinated me. After removing the EMI filter in the heater supply box of a normal microwave oven magnetron I was able to get clean 1.5kW pulses as short as 300ns using the GMI83V to switch a -5,5kV supply into the magnetron's cathode. As a grid driver I used a Mosfet that was driven by an Atmel ATTiny2313 running a simple assembler program. The grid driver mosfet pulsed about 100V into a wide band ferrite transformer, the secondary of which was connected to the grid. I remember that i needed to bias the tube somewhere below -200V to get it completely cut off. The average HT power consumption at a PRF of 500Hz was low enough that the ignition transformer of an old oil furnace was sufficient. As a receiver I used a modified analog TV wireless link. Display was just an Oscilloscope, range was around 25-30km against Airliners (A-320, 767 etc.). Obviously not recommended to replicate this project at all, even though it was in the ISM band and thus not a completely forbidden frequency. When I had the first 3-4 screenshots of aircraft echos, the whole thing got disassembled and never turned on again. The modulator chassis and the modified magnetron are still around in some cardboard box in the basement...
@@tpa6120a2dwp An oven magnetron is far from the best choice for pulsed operation, but I'm glad to hear that you have built a modulator pulser - it can be very complicated, with apparent simplicity and sometimes too tough for nowadays low-voltage oriented "engineers".
GMI-83 is also a great tube, but was copied from the 715-C tube, which can be seen in this video. As well as GMI-83V. On the contrary, GMI-5 and GMI-7 is an original and very successful design in the range below 30 kV.
@@Magic_Tee My choice of an oven magnetron for the project was more or less mainly that I could not find anything on the internet at that time that somebody had tried it before. Also, this strange world of high voltages, currents and fast pulses was fascinating in itself for me, I had never worked with anything like that before. So this was more of an experiment on whether it can be done at all and what kind of performance can be obtained. From a technical standpoint, there are two additional reasons: the voltages and currents required are low compared to a real, proper pulse magnetron, thus making it a "low hanging fruit" to try as first experiment. In a microwave oven, the magnetron is generally run in a single pulse rectifier doubler circuit, i.e. when the label on the back says the oven has a power of say 700W, the magnetron actually only runs every other half wave, so the power is about 1500W for 8ms or so, then the magnetron is off for 12ms until the next 50Hz cycle comes. In the time the magnetron does not oscillate, the capacitor of the doubler is charged. So, effectively its a 1500W magnetron running at 40%ish duty cycle. The voltage and current when it runs was 4.5kV and about 0.6A in my case. Another important reason was that the frequency is in the ISM Band where there are plenty of industrial applications where some of the RF always escapes, so me goofing around with a puny 1.5kW at 2.45GHz would maybe cause some bad WiFi in the vicinity but otherwise go ideally unnoticed. Regarding the GMI83 and GMI83V, I found that all the GMI83 (the 715-C clone) that I purchased had drawn a little bit of air and were defective. The GMI83V on the other hand were all in perfect condition, I absolutely agree those tubes are excellent quality, very easy to work with. I also tried using the GI-30 in the modulator, but this was less stable - I noticed a weird pulse length jitter that I could not find the origin of. Also, the magnetron appeared to jump between oscillation modes during the pulse which could be observed on an oscilloscope connected to a RF power detector. At that time I also had access to an old HP5372A modulation analyzer, so I took some measurements of what the frequency was doing during the pulses. With the GMI83V there was a lot less FM on the pulse compared to the GI-30.
@@tpa6120a2dwp Ah, now it’s clear what was required from the system. Nowadays this of course can be done in a much easier way, with FET/IGBT Between cathode and ground, with a storage capacitor. BTW, the oven magnetron can be forced a lot by changing magnets with stronger one - with boosting anode voltage it can give up to 2 kW with proper cooling. On the other hand, I meant something different about pulse mode running, saying closer to classical 0.3-2uS pulse width with voltages of 10+ kV - they can give some pulse output, light up a neon bulb or so, but their cathodes cant produce same current density as indirect heating oxide (especially on high PRF and D-cycle), so the peak pulse power as a peak-factor is pretty low. Besides that, at short pumps (like 1 uS or so) they start to oscillate in floating mode (jumping from normal п-mode to the high order electric field-patterns and back), which also increases power drops to the output. And finally, due to the Child-Langmuir law, a specific effect occurs when the anode current does not increase and even drops above a certain voltage value due to the "dip" potential near the cathode ("reflecting" electron-cloud near it). So, something like that.
As for GI-30 it`s difficult to predict it behavior in modulator switching - originally, this tube type (which translates as "oscillation pulsed - генераторная импульсная) was design to work with coax UHF/VHF high power oscillator or amplifier with grounded grid. Especially big versions like GI-19 or GI-7B and others. But I`ve seen GI-30 in vintage pulse modulators as part of "clocking-blocking" oscillator for driving a bigger hard-switch tube like GMI-90.
My father's first hearing aid had two very small tubes, like the one at the top row, 10th from the left on the black board at 2:20 . . .
and a HUGE battery in a separate container with a shoulder strap.
I am from California. I have cleaned up a mess from many earthquakes. Even a small quake, like a 3.5, would knock all of those to the ground. I think some kind of barrier should be installed to keep this collection safe.
I live in Houston TX about 50 miles from the gulf of mexico. It is a mud flat! No earthquakes here at all. But we do get an occasional hurricane! My house has been here for right at 70 years. Not worried!
Hey Ron your tech friend Dave here your video was amazing it was nice seeing all those tubes thank you you have a nice collection it was a long cold winter and I missed your videos I have a lot of tubes in radios myself retired hope to see another one of your videos soon may God bless you and keep you safe always your friend day thank you
OMG, so many types of tube, semiconductor, speaker, etc collection.
