 Hello everybody and welcome back to my V-LOG to my channel, I just wanted to show you some of the quick here and that's in regards to some of these chips you get, these are the TDA 7294s and I want to show you the difference between what you can get off eBay and what the actual genuine ones look like. So first of all I'm going to, there's the reason why it's a bison genuine, it's because of these actual chips, let's just zoom in there a bit if we can and get that to go over to this. And you're going to see the markings are relatively similar to a peak at that and one of the things that does give it away sometimes is when you see on the back, let me just wipe this off because I don't want to knock on the back of here, and you see on the backs of these things this is an Arctic MX-4 non-conductive, non-conductive thermal coupling paste. You tend to use this sort of stuff with CPUs and I've always found it to be great. So on the back of there I mean that doesn't look too bad but you can see the sort of shape that it is. You can see the sort of shape that it is. It's hard to tell what sort of condition these legs are in but they don't look particularly too bad. Now let's just put that to one side and let's open up this packet here. This is a port-off EVA. My first thought I'm just replacing these inside here but then I thought to myself after I'd ordered them I thought well it's 16 bloomin' pins per one so that's gonna be a bit of a pain job anyway. So rather than do this and then find myself regretting it, find myself regretting it, let's get some genuine ones. Now the first thing I'm gonna point out is the state of that. Alright now as we can see let me just get the light right here so we get a better view of this. Alright I'm just trying to get that into a better view. It's quite hard for me to see what's on this part of the camera to pick it up but so you get to see that these markings look you know okay but it's the rest of it. I mean look at these legs look whatever that is that's on them that's making them look like that. I think it's just part of the the processing whether they're not cleaned properly or whatever's going on. So there's a general indication I don't know what this black is. I'm just trying to see if we can scratch that off. All the way over that is what's actually under the metal. Let's just take a peek at another one random one just. Oh wow that's even worse. So we can see that the manufacturing process doesn't look to be that great. I mean these are supposed to be new they don't look like they've been used before but they look like. Oh they just don't look that great. Now here's a couple of brand new ones from Farnell. They're in a box and let me just back them out of it for a box anti-static. Now I shouldn't be too. Let me just let the anti-static thing on. Now that's the nice thing about this right is there's two in here. Now these are not cheap these are like between 10, 11 pounds and they're not cheap. If anyone's wondering whether I'm protecting these from static. We can look at this here and we can see first of all we can tell that it's much easier for the camera to see in on this. I'm gonna actually push that zoom in now. Much easier for us to see the markings and the whole thing just looks nicer. Looking around at the tab as well. I don't know if this is just because it's not polished off whether that's mostly polished or not but the legs look at the legs. There's no decoration on the back. Let's just remind ourselves what one of these ones looks like. On the back it's completely different. I mean it looks like it's the same but it's you know genuine you pay for and this or maybe there's a difference you know one's just produced cheaper and either one's produced more expensive but I got a funny feeling what you can't see as well. That's why I'm trying to get the markings to show up on these. Let me just see if we can just tilt that a different angle. There we go. So you can also see then that even though these markings seem to be in the correct place they're not as well marked as the definite genuine but it's the whole process is just cheaper. So if that's what it looks like on the outside what they're happy for you to see. You can imagine what the state of it's going to be on the inside and then you can just imagine that because I'm not going to break one of these apart to find out and it's not what I'm about to do. I mean I don't want to break them one of these so much but I'm not going to and I'm definitely not going to break one of these to do a comparison. Like I said I think I've paid 11 pound each for these. Just to see what they're like but there you go. A little bit of a Luke and we'll see how this performs. Let me just back out again. How this performs when I've swapped out these ones I just didn't really give much of an output at all for these and hopefully they don't shouldn't sound too bad. There you go. Anyway guys thanks for watching and I'll catch you next when I deliver it. Give you a little bit of a show of what's going on here. So I've got one circuit down now just waiting for some transistors to come in. So I wanted to use genuine transistors in it and these are the transistors for it. We've got a couple over there to get on with and there's one over the back down there in the middle of the screen. It's useless that I was going to shave it and you know it is useless so there's no point or maybe I should just to say don't bother buying it. It's one of those ones that's just no good at all.
