 YouTube. So I thought after reading the comment left on this particular or the previous video to this regarding this little circuit, yeah, you know, I should be probably looking at doing a bit more testing on it. And so what I've done is I've set it up like this and I've connected an 8-ohm dummy load instead of the speaker. I've got that connected over there to the source code and I've got a one kilohertz signal over there at 40 volts or 40.40 volts, which is probably actually quite a high for this. That's 400 millivolts. So I could do it loud, but just for the sake of this, we'll keep it like that. And I'm going to give it 9 volts again and we're going to start a look and see what that looks like on this. Let's go. You know, you guys can see my top's okay, but the bottom's flattened off there. And this, I, because I've already had a little play around with it, we've got a 1.5k resistor here because that's what's on the drawing. And I'm just going to swap that out and sort that bottoming out with a 1k resistor. So we just changed it over and we can have a look at it again then. There we go. I've still got that carbon resistor in there. That's a 1k resistor. Let's pop it back in for 9 volts. We've got our 9 volts back. Look what we've got there. That's a lot better. Not perfect, a little bit on the top. I don't know whether that's because I've got too much on the bottom now. But I know that if it was on the top like that, if I just bang this off, we're not on the top like that. If I up the input going in there, as you can see, that starts making that worse. But you can run this up to our volts. Of course, you're going to get more bang-pier blocks. I'm just trying to sort them light up. So I'm going to have some extra glare. That's better. So if I just turn this up to around about, but if I start turning it up now, you can see we're going nice, nice on the way there. And that's around about 11.41, 100 million. That's quite a bit, isn't it? I'm just going to turn that up to 12 volts. Let's say 12.1. There we go. Okay, so what I've done now is I've left that resistor in the 1k to the 1.5 volt. And when it was at 9 volts, it was about 60 or 70 milliamps, wasn't it? But now look, 22, 23 milliamps. Let's see if they're still quite nice. And that's at 30 mini-volts input on the sideway. And even if I turn this up now to 12 volts, which I'm going to do now, let's turn it up. There we go. 0.32. And that's better than what it was with those other transistors. At 9 volts, which is much better, of course. It doesn't do anything wrong over there. And if that is on there, we'll just bring that down a little bit and then just turn it up on the input side here. Look, it's quite happy. It's quite happy. The transistors don't really get warm at all. And this is I'm using now the VD 140 and the VD 139. Oops. So yeah, so we've got the 139 there as the NPN and the 140 here as the PMP. Much better. And it sounds pretty good as well. And you know, almost sounds like it's got that little tiny bit of extra oomph base to it. But nothing, you know, that you could really go right home about or anything. But I'm quite, I'm quite terrific just by playing around. And I'm glad that the chat that spoke out on the amplifier side is giving me too great piece of advice, really, to play around with this more. And that's really good because I'm quite chuffed with that. I'm chuffed because it's using so little power. And at 9 volts, even with that extra input, let me just get it down to 9. Even with that extra input, we haven't got any problems, any problems whatsoever. So yeah, so I'm gonna just do a little bit of a sound thing on it now. The same music as what we heard before, but we've got a lot less on the power. Because if I remember rightly, it was over 100 millivolts. Sorry, 100 milliamps at 12 volts before with these other transistors. These are the 2S D882 and the 2S V772. So they take quite a bit more compared to what's in there now, which is brilliant. And we've got rid of that, the clipping on the bottom, but getting rid of this 1.5K and sticking the 1K in there. It's a lot happier. And I just like the idea that the current drawer has gone down. But now I'm going to connect to speaker and we're going to see if it's actually lost any of it at 9 volts again or just under 9 volts. Should probably set it to like a 9 volt battery and just give it a double 9 volts, but let's just play with it the way it is just for a minute. Now put the speaker on. Okay, so I've got my music source there ready to go. And I'm going to drop a battery and give it its power. So at the minute it's on 20 milliamps. I'm just going to turn it off for a second because I've got no idea what they're going on about, but not that it makes any difference, not trying to make out what they're going on about. Let's put something on that needs, it does sound sort of non-fush. Now this is full blast. And remember before when it was full blast, it was like, when it was clipping, wasn't it? I was saying it was ripping, but clipping, clipping, 14, it goes up to 15, so it's not quite full blast. I'm just going to skip it to the middle. So let's turn it down a little bit and then I'll just find another track because that's, I thought it was going to actually have some extra sounds to it, but never mind. I can't put on too much, too popular because, you know, the thingy police. Yeah, turn it down. So it is, it is, I mean, loud. That is loud. With two speakers. I'm going to build you a channel and then try and find, I don't think I've gotten to one of these speakers, but I'm going to try and find a couple of speakers the same. Try and find something a bit more oomph to it. Well, this one's got quite a bit of oomph, isn't it? Full blast. And I need to say as well that these are not like, flak tracks or anything, you know, full and loss less audio codecs. I think they're like 192 rips. 192 kilobits, second rips. So they're a bit rubbish, really. Not rubbish. I mean, they're all right for doing what I'm trying to do now, but, oh, this one's got quite a bit of oomph to it, but you need two speakers on it, I think. Well, I decided to just add this little bit onto the end. Look, I've turned it up to, yeah, 12 volts, and I've connected it up to that speaker there. And through these, like, rubbish wires and stuff, with, like, one now found resistance or something stupid on them. And I'm going to, oh, a little sander. The reason why I've done it like this is because I can't, even if I set up the two channels, I've only one channel on this works. It knackered up a long time ago, and so I've already got, that's why there's only one, a bit going out there, there's only one channel works. So I can't really do a great deal, even if I set up the two channels, which I'm going to, and I'm going to put them on the PCB as a permanent fitting. I've already got two channels that work, one channel that works off my, off this frame here. So, and I don't want to, the sound with this frame that I've got in my hand and the picture quality is better and everything, so I'll have to try and devise a way of sorting this out. But listen to this look, this one, come back. Listen to this look. So that's on full blast. Right, the first one, full blast, look, 15. Two more seconds. Hey, you know that is worth a thumbs up. That is kicking, that sounds nice, it's nice and loud, it's only one channel, it's plunky. Do you know what I'm doing? I'm going to do the two channels, I'm going to get my laptop, because it's not killed my phone, so probably won't kill my laptop. I'm going to have it coming out of my laptop and I might even, because I've got some flax stuff on there and it's a good old laptop, it's a Lenovo Y5070 and it will probably kick out a little bit louder on what this does. So I'm quite excited, I'm not sure if that's, I'm very excited. Yeah, so the next one, I'm going to have the two on the go, I'm going to be connected to the laptop and we're going to have some nice stereo sounds coming out, because you can tell the difference, can't you? With the different speaker. Okay, so we can tell the difference now. So the different speaker is a lot harder to drive and this thing's still doing it. No, no heat issues whatsoever. Nothing, just, just, that was mildly, terribly warm, but that's it. That's it. And it's, you know, just quite happy to do that. So chuffed his points, just got over thumbs up. Right, catch you on the next one guys.
