 Hello YouTube. I just thought I'd... I just been fooling around with this little bit. I know I haven't made any changes or anything like that. The only thing I've made changes to this setup. Here's a little listen. Nothing. It's plugged in, it's all turned on. So look, there's a quiescent current over there. That's for both. It's just warming up. That's voltage, 50 volts. And the only thing I've changed is I bought myself some new speakers. These are Q acoustic 3020s and boy oh boy do they sound nice it's inspired me to take my CD collection which if I stack them off on the floor it's just slightly taller than me so it's not a massive collection but I've got quite a few CDs and over the weekend in between going out playing with the children and grandkids I decided to start flacking them all and children and grandkids the the music but in my Linux system I was using Linux lights and I didn't have the right codec so I just used wave form with no compression and I built myself a big collection so I've got the whole bunch on my laptop here and it's an absolute pleasure listening to this thing and you know I've been looking for enclosures for it and they're so expensive especially the metal ones so I think I'm going to do I've seen it's a John audio tech he's got his listening height amplifier built into a plastic enclosure so I will take it as I can use a plastic enclosure then as if he's doing it then chances are it's all good well not chances he's all good so yeah I just thought I'd uh for the for the buzz I I just you know I wanted to I was even watching some videos on hummingbirds and so I'll just put this back on again because I'll continue running in these speakers but there's nothing is it nothing I mean you you have to really listen to see if you can hear anything and really no I'm so chuffed and even if I put my hands over places because all these wires are sticking up then might as well be pretty roofed up on the tenants for this thing and there's no screen or shielding on the power supply side of things so really really happy with this really really happy I probably will have to buy the the better parts and build another two with the better parts and just see if I can maybe compact the whole circuit a little bit more because there's plenty of room there look for to compact it in but as it was mine just first attempt of just doing the layout and again all on and getting it working I'm not going to give myself a terribly hard time about it yeah I'm really really happy with this honestly if if anybody is out there and you think to yourself I want to build a little amplifier circuit I'm promising you absolutely 100% you will not be disappointed with this particular amp not disappointed at all and I was yesterday when I got in the evening my neighbors must absolutely adore me because the floors here are like a ceiling in a normal house and I got a a new um what's it what's that album called the new it's not a new album but it's back then and now album oh my life you know it's just this this thing rocks between those speakers now they push right up against the wall as well and the ports on the back but I put the bongs in in the ports and there's no boom there's no nothing that you'd be and it's nice because they've got magnetic oh let's pull that off look at that beautiful I and they're all the speakers I looked at some um darly speakers but yeah they're not lovely but I prefer just a little plain and basic but sound absolutely lovely oh look little little magnets mm that's how transparent really that is like there's absolutely no um no no pulling this no no muffling the sound at all from there but these things are absolutely gorgeous I got them for 120 pounds from down south made made in head they sent them up ordered them in the afternoon I had them the next day absolutely brilliant uh yeah so all that was with delivery as well I chatted to the bloke quite a bit you know going the friendly side get the best price for the day and I got it and that was including delivery as well so really really chuffed I did think about you know trying to replace my 73s and I did find some but they wanted 60 pounds for them and I just thought oh you know it's quite an old design I may as well just uh I may as well just buy myself some new ones it's been a long time since I bought myself some speakers the last speaks of all with the kekai q3s for my lounge so and I wanted some they're halfway it's not halfway decent in here but not too big I may just seem to be absolutely great I just had to pull the rack forward very very slightly just to accommodate them and the only reason I put that little bit of sponge underneath that uh was just so I don't scratch the bottom of the speakers because the feet that you get are slightly well they they would be no good set on the rack the rack would sit in between the feet and I just don't want to scratch them don't want to scratch them keep them nice for as long as I can and I got a warm up ones because I just love wood I didn't really like wood so hmm I'm going to be chuffed I might just give you a little tiny bit of a listening pleasure even though you probably won't get the best but you might be able to compare it to the other sounds the other ones and consider it quite nice okay so what I've done is I've um I decided to hook up her dummy I put into the skirt just forget about the fft for the minute I'm just I'm not involved just doing that at the minute I'm just looking at the sine wave and I can I can pretty much see if it's clipping or not I just noticed that I've got this set at 250 volts and it sort of sticks it's a little bit annoying so well I'll quick show you I've got 2.6 volts there that's peak to peak because it's going down that sine wave at 1kHz and then I'll show you what's happening so we'll see what it's doing over here current wise nearly an amp current we're not clipping at all and we got 16.5 volts okay so I'm not going to put over it too long the only thing to happen to it is not getting really hot it's sort of lukewarm even if that so I'm not not particularly bothered to know I've done the math already well I've done the math I used to calculate so look what do we have so if I just cancel out I'm doing again so we have 16.5 square that equals to 272 divide that by the 8 ohm load so we've got 34 34 watts so I'm wondering when it says 60 watts and 20 ohm loads only that means 60 watts is in stereo not 60 watts per side so I'm going to imagine this it's not there but but look even though the power's off this this thing's sticking and that freaked me out first when I first noticed it stuck because I got it disconnected you know here and I could see there what's going on here but yeah so I could probably you know try and see what could just stick that little bit extra but if it does mean if it is if it is saying because it was 16.5 on there wasn't it they just square that again and then divide it by the 8 any time you like so yeah 34 it's definitely not 60 watts coming out of there 34 so I don't think I'll be able to get that oh I don't know maybe I can from one transformer it's 160 va so I should be able to get even if it said you'd like a 50 efficient you know 80 watts so so maybe that was just a little quick thing I wanted to do that just because I keep playing with this no I absolutely love you know I love listening to it and as I think I showed you in the first bit of this video of course I got my my new speakers which sound absolutely cracking with this thing hmm yeah I just I just wanted to just do that little quick test and share that with you just in case Henry was wondering you know what I can actually get out of this and remember we've not got the greatest of the components here we've gone for the absolutely cheapest of parts just because you know this whole setup that I've got is pretty much it's about this cheap as you can get really the whole lot I'm gonna do it I'm gonna do a video about what I've got on my bench what I've got why I got it and how much it costs and if I tell you I've got pretty much everything here forget the speakers on my computer that's not really fair you know my laptop and my main computer you can't really put that in because the speaker addition but if I set the whole lot everything not including the bench you know just the the kit as it were was less than 700 pounds you might be surprised but I'm telling you I know it was and so I've actually put a little bit extra on that as well money-wise just because it seemed like it was too little but that's what it costs because along my stuff you know is um second hand bits and just making bits that's a spider look I've got a friend hello mister yeah he won't bother me so I'll just leave him to get on with his life yeah so there you go there's a little quickie so I'm here a few minute video this one so I will um I'll see on the next one there's somebody asked me if I'd do a thing on this um this meter and asked me if I'd do another one of this because the first one I did on this was pretty terrible but you know I'm petrified about making reviews on anything because I just don't one thing I don't have anything to compare it to that's like industry standard to say whether it's after it or not to I can't be bothered with all the modes on it because I only use it for testing transistors so and that's all I wanted it for and it does that it does the job for that so for me it does the job but anyway I digress still love this little lamp and I would still recommend to anybody out there build it enjoy it it sounds cracking and as you would have heard in the first bit of this video there's no noise from it you know you don't get any harm you don't get anything from it so it's pretty damn good when there's nothing when it's not plugged into anything you do that's because it's picking up you know everything from there is quite sensitive if you touch it making all all right on noisy noise uh there you go well it's quite late at night here so I'm gonna be quite quiet because the lady is trying to get herself to sleep probably so cheers watching guys I'll see you in the next one 34 watts not bad
