I really love tube circuits. One of these days I'll get around to finishing the tube amp that I was making with magic eye tubes to show the levels on the two channels. I don't really need it, but I have very fond memories of a radio my grandparents had that used magic eye meters that I was absolutely fascinated with as a kid. There's not of devices left these days with those style of level meters that are still working or reasonably restorable, but the magic eye tubes are all over eBay fortunately.

Vintage circuits can make a very good series. Please make this series.

[@Delali]

Seeing this video, i realise how much i miss you, your amazing videos and accent. I have been away working on my own channel. Feels good to see you my friend.

In this style of radio the iron core is the directional antenna, so it would make sense that you touching it will help with gain. The audio output of these circuits are typically high impedance at least 2k ohm or higher. If you were to use a crystal radio earpiece without the transformer you may have had better results. Or earbuds after the transformer would have worked as well. The 3 tube set will allow you to drive a speaker

[@barrymayson2492]

A lot valves use transformers in the audio output which might account for low volumes. Just a thought. Great to see you try out things that take you into new areas.

[@ConsultingjoeOnline]

Love the projects!!!

[@rinokentie8653]

Nice project! Your anode supply voltage is very low causing distortion and low output power. These valves are typically suitable for 70 to 90V.

[@AnandKumar-ym9yw]

Love this project, next should be on FM transmiter 😍😍😍😍😍

[@mbak7801]

You could use 3 PP3 batteries taking the supply up to 27v. Also check the load impedance of the 2P2 and the turns ratio of the transformer and see what impedance speaker you will need. Using the wrong speaker can really mess things up as well. All in all it looks an interesting start for experimentation.

Nice video!

Wish you all the best .. hard working and very smart guy

[@DIYwithBatteries]

That was cool Bro 👍 yes it's fascinating ;)

[@PhG1961]

Cool project !

[@CasualyCompetitiveGamer]

For finding the MHz you can do 1/2xπ√LxC L(inductance) C(capacitance)

[@VoltageNostalgia]

Great video thanks

[@Dinocelisaandtonni]

Pcbway es carisma!

[@Wtfinc]

Oh thats cute! I think i have all the parts!

[@kayezero703]

i was watching your "make an arduino at home" and i have some questions

[@leehewitt9559]

Love it !!👌👌👌

[@zentheplayerrapper8504]

Esta bueno :v bro saludos 💪😉

[@mohamedaqeelmohamedsufiyan9996]

Hi I like watching your every video And I have tried most of them If you can please upload video based on Induction cooker how it's circuit works And how to make a diy Induction cooker

Please make a walkie talkie in vhf range

[@eletronicaeautomotiva]

Excelent project

[@captmohelsaadany6751]

I have a couple of 6cb6a vacuum tubes Can i use them for this project?

[@pie9967]

Can you make a tutorial on how to use Nrf24L01 with Esp32 Dev kit

[@VijayaLakshmi19807]

Sir this is really nice project. Try to improve audio quality and Also try to make a radio transmitter. Please don't forget to make a video explaining the uses of capacitors and how to use them in circuits effectively. Love from India ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

[@wild-radio7373]

COOOOOOL!!♡♡♡

[@taranagnew436]

what do the tubes do on the radio?

[@joseluisfernandezrodriguez2241]

Como no saturaste más la señal a las válvulas y sacar el audio con chicha y más saturación en la remodelación.., después filtrar con condensadores.... Casi ni me acuerdo cómo eran esas viejas radios am de valvulas

[@parsavosough4277]

niceeeeee❤

[@Pulverrostmannen]

I think the device would work better if you ran it with more than 9 volts, since tubes are high impedance devices they will work poor with low voltage plus you get very little power out of it as well which tend to distort. too bad in my country AM radio is not available at all so it is pretty much useless here

[@ELECTRONOOBS]

I will try. I've used them at 12V but I was afraid with more than that since the schematic was marked as 9V. Thanks!

[@Pulverrostmannen]

@@ELECTRONOOBS as long as your capacitors are rated for the voltage these DL92 tubes are rated for a maximum plate voltage of 90 volts. And the G2 grid should not exceed 67 volts so the tubes have a good headroom upwards. However does these tubes have a very small output with a maximum of about 270 milliwatt at absolute most so you won’t get much. However is the power increasing with the voltage. But check that your resistors are suitable for the increased voltage so that the led and other stuff won’t take damage. Otherwise you could probably safely go up to 60 volts without any issues :)

[@NiHaoMike64]

@@Pulverrostmannen Easy solution is to just omit the LEDs, actual (old school) audiophiles consider LEDs under tubes like putting cheap ketchup on fine sushi.

[@Pulverrostmannen]

@@NiHaoMike64 ha ha I know right? I have built several tube amps and have a complete hifi system which I built myself and I didn’t use any LEDs to light my tubes. It’s better to use tubes that glows much to begin with instead ;) that we all like to watch! Nothing like 500 volts feeding tubes glowing with red hot cathodes. Omg I like that!

[@mr.q3216]

Like someone said you need an AM antenna.

nano-micro vacuum tubes as transistors

[@Wtfinc]

When you show the schematics, can you do us all a solid and show us straight on and don’t move it for half a second so we can screen shot it. It’s just so easy to screenshot Edit: I tried using your link and that website is just the worst. Theres no actual download link, just a bunch of traps that look like download links. And for some odd reason I couldn’t save it to my photos like saying. And its not from a lack of trying. Idk

I need the board. Can you give me

"let's ged starteth"

[@longdongsilver4719]

Am I the only one who is surprised by the low 9V power supply for a tube? That's way too low. Even for a tube rated at only 60V.

[@Amperekaefer]

👍👍.

[@ChrisLocke1969]

that speaker is not so good - I've tried them in projects... try better ones

[@arjanbroekhuizen9298]

use a better speaker for a better result

[@de-bodgery]

This might have been 100% a waste of time.

[@VoltageNostalgia]

Why? This is great information to learn. If the Internet goes down, knowing how radios function and how to make one is invaluable.

You are telling lies want you try running your motors forward and backwards
