 Hey there YouTube, okay, so I've got a bit further forward with this, no I found a mistake and the mistake was this connection here was coming to the base here and The collector here Oh, what was it there? Never mind. It's fixed It's fixed. Oh You're at the same stage as what I'm at now apart from I've gone just a little tad further in front of you So at the minute we got That says 0.5 volt. That's peak to peak Just connect it and see what we've got there 4.4 4748 volts or a nice Okay, and I've got 24 volts going in And Drawing under the current I'm supposed to get 20 milliamps But I don't have any heat sinks or anything on I'm not getting any heat I'm not getting any heat on anything. I've got nothing on the output of this anymore There's nothing on the input. That's nice. I've got no DC Anyway, so That that mistake seems to be fixed. It's really really good. It's what I'm gonna do now is I'm just gonna just turn this up Well, I may as well do it With you watching so I've got that set on 250 volt. That's good So here we are. I'm gonna start turning up what we want is like 50 volts Just for this little test Even though it says 4.5 now, it's not really going up that much But the quiescent current's going up That's on sort of 40 so 45 so because there's no heat sinks on this I'm gonna back all that off Feel So good so good everything's good. We definitely got amplification Definitely got amplification and I just wanted to see just turn it up there I don't expect it to go up there Because I need to open the input the output, but I just wanted to watch that it was no Weirdness. It was like I said, you're at this stage. I'm at now so I've just Finished just making something to eat there and I'm gonna just stuff my face take a bit of a chill from this and Come back when I've been eating See where we go from there Okay, so I'm back. I've Well, I did the scope thing I have not plenty of quiescent, but I got rid of the resistors Because I need to have a little bit of current going through it now so it's on At the moment these two are on the current. So this is on the let me just check for you. That's on the negative rail This one that's the current there And this one's on the positive And it's on now. It's pretty much. It is lowest. It's about 30 million 50 volt Quiescent can't really Like I don't want to just try and blast the crap out of it. It's just nice to know that it works And it sounds nice It does something This is literally you get in this the same time as me I've not done anything apart from connect the wires up and then I Tested it in the phone that I'm using at the minute because it's really got one channel here And only one channel on this phone works. So I didn't know if it's gonna work play test it in this camera phone first It worked Found this phone It's good We've already got one one channel It's all free music It's gonna taste a little bit. I know what it's going to sound like The music don't put the music to my taste or anything like that. It's nice It's just just freebie stuff and it gives a wide range of sounds That's that's what I go for that's why I Prepared to send this into the classical stuff one of it This one's actually called Trevor boy So I'm gonna give me self this they've sort in this out Okay, this is definitely gonna have to be a two channel amplifier and of course I'm only putting 25 volts inside. This is actually For 35 volts aside Be pretty good in this but I just wanted everything to be on a bit of a Let's not push things and let's just see how things go mode before So it's got a 50 volts going into the minutes with a 25 volts aside and We're on a quite low quiescent point if I If I just pull the power on it, it's gonna pull the power you get what's in the capacitors now There we go. You've lost it Yes, I'm kind of as I mentioned that before That's because I just can't through there anyway, so we've never input Should be able to see what that is still shouldn't it is just that 50 volts. It's just slightly off So I just don't plug this I've got some fuses here. I was thought about pulling in I didn't ever could have come to me. Maybe somebody tell me these are resettables any 30 volts, I'd still have to use the Variable transform I still have to use that to keep it, you know, not love Because of the 25 volts of the AC output here pitch and all we're gonna get like 35 36 volts. That's not me DC So as long as I use the auto transformer I can possibly use these Just does some sort of protection on there resettable fuses or can I use 250 volt 3 amp fuses? I'm not sure mega just Google it It works It works And I'm gonna show you some current Voltage that looks a little bit up. I presume that's something to do with the fact that there's a speaker cables on there now And I probably don't want to let us keep climbing but we do see that when the Yeah, when the Oh, that's quite possible. I didn't even got to see that in the video. That's all raised up And then drop down That would be the positive rail. I Just did that The left one is the negative Interesting, but that's because I've got this speaker on look at a cable is it's already far cable It does say about the capacitance and And I've been reading as well, you see I was stuck into books yesterday on amplifiers To me yeah and the M4 section and it was talking about the the internal The capacitance in this or something if it gets together. Oh, I don't want to try and explain I can't remember properly. I'm just too excited that this is working. I want to go and play with it I just want you guys know that it's working It doesn't seem to do anything terribly untoward These resistors are out of line now. This is directly in and And I'm chef I'm chef done wish it was two channels. I'd be able to sit back and listen to the music, but it's not it's only one channel Yeah, that's it. I'm so glad that's done so glad that's done And when I get the money together I'll order the good bits the good parts. I haven't got any more 140s Otherwise I would build another one of these I've got everything else are no no no I've got the I've got these I've got these as well. I did the same value 0.27 so not 0.3 frees 0.27 that's all I got though, but it works and The only thing I was on 40s On 40 zone now Probably do some more of these green ones, but I can probably take it take about a couple of These projects. I'm not doing anything with now. That's an inverter. I don't know if you inverted with loads of different Must have it some stuff on there to be dissipating heat Hmm, maybe I just order Get some of those off eBay Nxp's I think the ones I got on there and nxp's and we're right But I noticed there was two when I was looking for these on far now. I noticed that there's some Different voltages and different some of these 140s or 3 9s or 140s now They're both both such expo. They only do they do 12.5 watts dissipation and either ones do like one and a half dissipation should I be careful when you buy these bloody things it seems if you've got two lots of 140s completely different Yeah, they can take the capabilities as a big difference in their capabilities and you'll be careful that you don't end up with some 12.5 watts and some 1.5 watts Not so good I took that bit in there. I thought I was quite interesting when I saw it Well, that's a bit of a bugger for some people say young players, but I'm not that young so I say new player for me Yeah, but trust it works, right? That's it. I'm just gonna roll this out a little time better music Cheers for your support out there. I'm gonna probably I will reply to you The bits I was gonna write down or maybe I shouldn't maybe you just get these videos or reply and I'll say I've stuck a video And I said I was just gonna play that a little bit of music and go out But we'll just listen to another track and it just it does actually this does It just sounds like these ones they sound quite nice and yeah with the two channels from like the n1975 Sounds nice as well. It's just that this one's just got there Listen to me think Let's get to another one. I don't know. I don't know what's coming. It's just gonna be in the order of whatever comes So I'm just gonna Get a bit of bass pulled on this It's gonna be some kick to it, don't it? I ain't gonna make you listen to that because I know there'll be some younger it is That's old But on the sounds of it, I'm just gonna Let's uh, oh, we heard this on me. I think it was on the Tube it's not like seven little three. I'm gonna give it some extra power That was nice Shuck it up to my Hello This is all Spanish and pretty loud Actually that sounds quite nice them speakers are like crap, and I don't Pretty rubbish if you want bass Old mad 30 20 years and years it would have had a hard time sounding like this But then again the sources were different as well So we'll think we've I'm saying that you really get out what you put in you put shit in you're gonna shit out And that's it. I don't care what people say. Oh great set of speakers. Yeah, let's have a look at your source And then you can amplify that Oh Sorry, we're just Getting trouble it will play this Again trouble for that one No, all right, okay That's in my 15 on my phone, which is absolutely rubbish But one half ounce of this joint And each time to turn it from a hundred million so I watched it like banging across a couple of times too much So anyway, that's it. That's it. It works. We all know that now I'm just even if it's getting warm terribly. No nothing's a little bit lukewarm. Oh, this would be nice Yeah, we can really love that
