Think of of vacuum tubes as analog mosfets/fet transistors, (tubes are are solid state but logically are power hungry ) using voltage to move electrons(by reflecting or attraction) physically , instead of silicon(mosfet) where the flow is directly switched, only needing 3 connections and much less power, think of the tubes like the Atari vcs and modern day transistors like a gaming pc, they both are "able" to do the same things just two different techniques of achievement

@@Clancydaenlightened worst explanation ever

For me transistors are more of a black magic than tubes. Its easier to understand how a tube works than a transistor. But if you dont now how it works, it really looks like magic in a glass tube.

In the USSR, they also liked to make powerful amplifiers on this tube

I'm really not sure how may people would appreciate a clock with TTL chips :). Those chips draw even more power than the nixies and they were probably made before most of the viewers were born. But I was already mentioning this clock in a video kzfaq.info/get/bejne/h7hje7uayrOne2Q.html and I'm also writing a webpage about it danyk.cz/hodiny_tesla_en.html

Hi time traveller nice to meet you again 👍

For that clock, what about put a small isolation transformer in the input? It could be less dangerous!

The man does not speak, he sings.

1959Berre You are right! Ha ha ha...

Hes's a Czech guy singing like Italians with an Indian accent... it's fabulous! :)

@@BillAnt Czech language is funny even for other slavs like Poles :D

@lukezaa < So is Hungarian, sounds like nothing else in Eastern Europe. xD

They're not expensive. Maybe because there's a giant old stock, or because audiophiles refuse to use something that wasn't originally designed for audio. But it still should be a good amplifier. I also prefer the single ended aplifiers. It's simple, there's no need for matched tubes and this is what you could find in all tube TV sets and radios.

In my case I purchased it from some guy who got it from technical highschool. Basements of such schools can be real treasure chests. They often give the remains to students for free. When it comes to electronics really like stuff made in Czechoslovakia, especially transistors. My favourite is TESLA KD502 (they were often used in Polish Equipment).I also have one Heptode TESLA ECH81. I really like your channel because you show old equipment and explain how it works.Keep up the good work.

@@DiodeGoneWild What does it mean that the Gu-50 was not designed for sound? And 6P3C (6L6) was designed for sound? Audiophiles are a biased people

Двухтактный усилитель на Гу-50 прекрасно работает и звучит. В СССР это была любимая трубка для усилка,не считая 6П3С и 6П6С

Some conspiracy theory says that Russia still produces a lot of tubes to be prepared for a nuclear war :).

i didnt mean to imply that its just a fact that those tube mutch more resilent to EMP

besides Putin migth be crazy but not stupid the one who fires first dies second

The tubes may be, but the other components in a radio are not. Don't forget about the diodes in the detector and modulator, even the rectifiers in the power supply, and the transistors all over the audio side.

you migth be surprised what possible with tubes recifiefer have bin made with gallium plates stille in use in old Carbattery chargers transistors have bin event in the 50 but similuat techniks have bin used in guss what tubes when in the early 90 a hole squadron of new Russian migs been taken over by the german Army from the Eastern German Airforce the have bin proofen mostly bin equiped with tube based electronics why do you think was that

I may build an audio aplifier to be able to enjoy those tubes :). Pentode has no solid state equivalent, but if you use just the g1, it's a bit like a FET. I still keep several CRT TV sets from nostalgy, but unfortunatelly they don't work, because all TV broadcast is now digital. But they work with a set top box (DVB-T receiver). I miss the grainy picture :D.

Hi there. Sorry for my English. The GU-50 are used in many ways. Like RF PA, in the UM series: greenradio.de/e_um.htm , greenradio.de/e_um1.htm , greenradio.de/e_um2.htm , greenradio.de/e_um3.htm ; RF end in mobile radios: greenradio.de/e_r123.htm ; or in even larger ones: greenradio.de/e_r134.htm , greenradio.de/e_r111.htm

Some kind of SSTC may be coming :).

I may actually build some audio amplifier with those :). VTTC is also a good idea, but I have already built VTTC's with 2x GU-81 tubes and with 6x RE025XA tubes.

DiodeGoneWild, please show the VTTC in your channel,I would like to see them very much.

@@DiodeGoneWild How about radio transmitter?

In my early attempts to build a vacuum tube amp, I was using some vintage output transformers from scrapped tube TV's and radios, But the power is not very high and the isolation is questionable. I'm probably going to wind my own transformer. I can use a core from a mains transformer and rearrange the EI core so there's a gap at one side. The windings have to be interlaced several times. For example PRI-SEC-PRI-SEC-PRI. This is necessary for better coupling (less stray inductance) because it has to handle about 30Hz to 20kHz.

Ah. Ok. I didn't know this about the output transformers for tube amps. Afriend of mine recently opened a musical instrument shop in the town where I live, after the last such shop closed 3 years ago. And I started to think again about making tube amlifiers. That was nice to know. There should be not much problems making an amp sound like one of the famous amps. There are many young guitarists that go into a guitar shop saying, forexample "I want to sound like Ace Frehley from Kiss" And if he can be sold a cheap but good epiphone guitar with humbucker pickups and a less expencive amp that sounds like a real (and very expencive) Marshall Super Lead then ...voila. Satisfied customer. I don't know. Posiibly. Edit: I have seen for sale quite a few high power tube amps on the second hand market. So, maybee a low power tube amp would sell. As guitarists like the sound of a tube amp when you turn it up high and the output tubes distorts. (They can't use their big amps the way they want because of their neighbours in the city.)

it's possible, if I have time :).

DiodeGoneWild ok :-)

I have some tubes from Tesla :).

Miquel an AM transmitter with a couple watts(or couple hundred :DDDD ) would be very nice:)

@@joczo97 On his website he have some schematics on shortwave TXes i think 5W max.

One lamp transmitter on GU-50 very nice. I made on 6p1p and 6p14p + 6n1p in modulator. 185V on anode. It producing 3W to radio waves.(1.7MHz pirate station)))

Sháněl sem jen pár zajímavejch digitronů do sbírky a nakonec sem přišel ke hromadě beden GU-50 :D Kdybys nějaký chtěl nebo věděl o někom kdo to shání, tak bych určitě něco věnoval. Mám toho víc než by duševně zdravej člověk měl mít :D.

DiodeGoneWild Tak to je hodně hustý a klidně bych nějakou tou gu50 nepohrdnul, chceš se dohodnout přes email, nebo nějak?

DiodeGoneWild Poptal jsem se a zatím minimálně 2 lidi by měli zájem.

DiodeGoneWild Písnul jsem ti email, tak dej vědět.
