Hey sir I want to increment with the push button but it is very tedious process let say i want to increment 0 to 50,000 and i will press the button 50,000 times and i search all over the places that how to press a button that increment by it self and when i release it will stop incrementing.
Can you guide me or make a code or tutorial?
Please sir
Thanks for updating this awesome channel - This is one of my best references
You are awesome, people hide vacuum tube builds like they guard poker cards. You've put up everything, so cool. 👍
I love tube amps, they are amazing. 😉👍
Another quality video. Thank you for sharing Andrei! I really enjoy your content.
Thank you very much for your comment!
Tube amps are just beautiful❤😍😍
Good one Electronoobs 👌🏿
You basically connected grandfathers to their grandchildren 😅
I loved watching this 3 times 👍🏽
Great presentation!! Please always use load (speakers) on both channels of the amplifier otherwise you will damage the output stage. Tube amps without a load will draw excessive amount of current and that will destroy the output tube.
Edit: you may notice a red plate on the output tube that it is not connected to a speaker.
why folks would listen with one speaker is beyond me stereo is the only way to hear music mono sucks.yep kills the output stage. oh the pain of blu tooth speakers mono units why why wwould any one have them lol
@@overbuiltautomotive1299 Indeed, it seems that most of these amp kits come with Bluetooth modules. For a beginner it might be convenient. Personally, I don't like the idea of Bluetooth modules, but most of these Chinese amps use them for marketing reasons and new-users convenience. On AliExpress there are good quality PCB clone boards of well-known amplifiers (e.g. audionote). You can buy separately the parts and make a good quality amp. The purpose of the video is to introduce hobbyists to tube amp setups, so I don't think that there is a need to select high quality parts and sophisticated circuitry.
@@angelosntimtsas2201 i guees the stereo units are fine but the tiny one speaker thing remind me of wen i weas younger and stuck a speaker in a pringles tater chip can lol good videos man be blessed man you may like the confessional pod cast host: tony merkel i figured i tell you of it
That was my first thing what I want to recommend. Never ever use without load!
...but there's one thing what grinds my gears... Why do they forcing that cr@ppy bt module? It ruins everything.
@@MMKaresz_az_eredeti yep uninstall it from circut and redo input to just analog plugs
Sir such great work and circuit clear to information tnks
Waw, great video !
Nice bro helping
Awesome 👌
Waiting for smart Solar Charge Controller & Nextion series....
Really cool looking kit. Funny how the old tech is making a comeback. I can't wait to see the PCB you said you are going to make. I don't know why they didn't make one for the kit. I mean I know it's supposed to be like the old school tech, but still, that looks a bit dangerous. Looking forward to the PCB for this!
Excellent project. ı liked it
Grounding the metal chassis would keep the box safe from loose wires right? Any lose wire touching metal would trip the breaker to the outlet. You could add a fuse at the input if you wanted to avoid tripping breakers.
Fantastic 😍😍😍😍😍 keep going 💪💪
Amplifier tubes ❤️❤️❤️❤️
I wish someone would make a tube amp kit with Magic Eye tubes for each channel. I've loved those things since I was a kid. For now, I just have to find the time to finish the one I am making.
Just found and subscribed. Could you recommend a small circuit class D amp board? I have two set of creative gigaworks T40 speakers with faulty amps but these speakers sound so good that I want to replace the faulty inbuilt amps.
Nice video, but can you do some measurements on it, just to see if it lives up to vacuum tube sound quality ?
Output transformers doesn't look very apropriate/promising.
Maybe you can do a 10 KHz square wave oscillogram or some distortion tests and share those with us.
I know this isn't intened to be a hi-end amp and personally I doubt an 100 euros kit would measure and sount great, but it wouldnt hurt for all of us to know for sure.
wow!
Does the ground for the transformer connect to the chassis?
just a suggestion under the transformer the wires going through the chassy put grommet to protect the wires from shorting out and getting electrocuted
I have a question Andrei.
I saw the schematics and would like to know the rating of the two audio output transformers? I see they just say 4 and 8 ohms but what about the step up voltage?
What amp does the primary transformer give out.
Dear sir video very good for us. But please help me with two types of SMD. which I can't find in the catalog. 34DG and L44. I don't know what they are! Transistors or diodes. I'm waiting for your answer, if you're good and want to help me. Thank you so much!
Could you please review some Rife machines which works based on vacuum tube and plasma? that would be very helpful with patients suffering from untreatable diseases. Thank you in advance
Ampli en classe A ==> 3 ou 4 Watts maximum. Les transfos de sortie sont très petits, donc rapidement on aura 10 %de distorsion. C'est juste un gadget à la mode avec des tubes.
👏😎
Great video but 8:18 - oh my God - that's quite messed up!! 😱 You could have used this video to introduce something like capacitive and inductive noise coupling and give some practical examples of how to avoid them 😁 that's the reason why every pair or more of wires are twisted together in any commercial and decent quality tube amplifier 😉
8:18... Ty-Raps wouldn't hurt... and some supports for the Electroylic caps... ;-)
how to make ir blaster
Using high voltages has high risks of getting electrocuted so if you want to follow along do so at your own risk or go with Philips/Raytheon low voltage wire ended vacuum tubes and use a heater voltage of 1.5-3V and a B+ of 45V and use a LT700 transformer to interface the tubes to the speaker and use the specified driver transformer to drive the grids of the vacuum tubes, you can also use terminal block connectors so you don't have to use a soldering iron.
i would loooooove to put ma hands on a 750v chinese vacuum tube amp lmao
Why there's always a Banana in your table...?? 😁😁😁
👍
the clue of the tube amplifiers is: connections as a web - without PCB ;-)
How much cost
Oh the irony.. Building an analog tube amp, feed it with music from a digital file and connect it to speakers labeled "digital" . 🤘
that's the brand label
i have it.. use 6L6
This just doesn´t look like 6z4 tubes. 6z4 tubes are full-wave rectifiers and you would probably don´t need two of them in a CT transformer. I am curious about what tubes they are.
Again, another awesome video! Any chance of touching on the balancing robot remote again?
Most of the tube amps doesn't use pcb. Simply just not recommended about the heat, what it can discipate. Trust me, I built few tube stuff ;)
Exoplain class d amplifiers 😎😎
Solder tags would be more traditional for valve equipment than PCB would.
"How It Sounds" is not a question. It would be fine as part of the title but it should not have a question mark.
Alternatively you could say: "How does it sound?"

The layout of this amplifier is badly designed. The transformer cores are supposed to be perpendicular to each other, not inline! If they are inline, they couple to each other
idont like videos of old tech
