      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

    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.

    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.

    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!

    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.

  • @messuceanu

    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.

    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.

    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 😉

    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.

    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.

    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.
