 Hello everybody and welcome back to my V-LOG, to my channel. Today we're going to be just taking a bit of a preview at this amplifier. This is a NAP 140. Now I don't really know a lot about the amplifier. This is another one of those from Aliexpress clones or you know copies. Okay well that was more difficult than I expected. Yeah so the difference is with this, is look at these transistors, 2SC 29922. I think they're all the same, yeah. Sankenbrand and that's what I sort of looked at on this and thought oh well that looks a little different. I'll just take a peek at that. Let's see if it fits out. Let's have a little look. So we've got some little heat sinks here. I don't even know what package these would be called. I'll put it up on the screen and locate it. Let's have a look then. So we've got two boards. Looks more pretty good. Now before I go in too much of this, I think what I should do is bring it up on the screen so we can have a look at the product. What's that say there? It's one note. I don't know. VBE less than 350 millivolt. Voltage base and a meter on the base and a meter, less than 450 millivolt. Note, is that for me to take note of that? Let's see if there's anything in there before we go any further on this. Let's just see. Let's have a little look at the screen and just see what we can see written about it. So here we are. This is the package that I bought. Not exactly the cheapest. Let's have a little look. This is £28. This is for the two. I believe this is for the kit because these are all kits. That's what it's going to look like. Let me just put that one there. Bit of an idea of what the layout's like and what it's going to look like once it's built up. All right, let's see what it says. Let's see what it says about it. There we go. So this is the 2C2922. It's Sankin's famous LAPT series transistor. All right. We've got a supply voltage plus minus 40 volts and I'd just like to say now that, yeah, I've invested in a couple of new power supplies there so we can go plus minus up to 60 volts and have enough power to be able to do this now without them to keep going for different transformers and not quite getting the correct recommended power. So let's just get past these. Let's see, a bunch of things are going to be seen in these packs. There's a little bit of a shania to hook it up. Oh, they don't say anything else with it. Well, that's not very good. Well, here we go. Right. So I'm going to click, I just want to find some information. So kit, we've finished, no kit power tubes. So that 29, I suppose that's for the two of them. Just looking at the price here. Here we go. So we've got some things, the optional kit, two channeling core, cooperating as parameters, size plus minus 40 volts, output power 80 watts into ATOM. Is there any more information or is that it? Well, I'm pretty sure that when I buy, I always check for more information and there's normally more information there. Otherwise I'm a little bit apprehensive on buying it. I'd like to know a little bit what I'm going to be looking for. All right then. Well, let's just say specifications. Yeah, no. Yeah, no, it's not. Oh, yeah, look at this. This is so interesting. It says the two channel including high power tube imported to SC 2922. The original British machine also uses the same transistor as two SC 2922. I've got no way of checking that. I'm just going to take it as what they're saying to me is, you know, honest. I'm just looking to see if there's any extra information. Because so far what we've got is copy and pasted. Everybody's doing the same thing. We've all got the same images. Yeah, but there's no extra information. All right then. So well, this one's going to be a, this one, we're just going to call it a mystery. So there's no, you know, output diagrams there for it. There's nothing like that. We got here. I don't know if it's going to focus in here. Come on. There we go. You can have a look at that up if you want to look it up. These will say it's an itch gun. Nice. Now, what I did notice in the images was there was a bunch of these like round two kilovolt, but they don't have any here. I think they've exchanged them out for these. They're sort of like the capacitors, which is pretty good. I do like, they do look nice and coloured well. As you see sometimes on some of these things, you're getting the colours half fade enough already or rubbed away. That's never a really good sign. I don't think. So we're going to say that most of this should be pretty okay then. And these are, I've got a brand on there. I'm trying to see myself. What's that HXB? Don't know what else we got here. BC546s. Nice. If they're, you know, Goodens, what Phillips ones or something, they should be pretty good. NCC5551s. All right. A bunch of diodes. I'm presuming these are 148 ones or 1IN4841s. By the looks of it, probably see them here actually. What it's going to have there for those. Can't see it. It's got big old, big old placings for them, considering how small those diodes are. But they are 4148s. I said 4841 and I meant 4148. Okay. Well, this should be interesting because I've been, I've never actually handled one of these before. I've never, so I don't actually know what package this actually is. It's nice and clean. Big. It's heavy. That is pretty, pretty darn heavy. It's quite nice. I like these extra little holes that I'm going to be able to see behind. Extra holes at the back. You've got the two big ones when you're siding the four around it. These ones aren't holes, but these, these ones are. Yeah. And then the leads feel nice and stiff, nice and strong. So again, nice. And yeah, they are pretty darn heavy. I don't believe how heavy they are. So, but yes, this is, this is the next one. This is what we're going to be building up. I'll get this done over the next day or two and get a video up so we don't have to wait too long to check it out. I do like these types of, I prefer these, you know, not quite sure about these little things. Not sure the little tantalums on it. Not quite cute, I don't know. Let's have a little look so you can see what it says on there. 390. Yep. We've got a little, uh, 24 turn pots. So it says a 202. Yeah, 202. So that's a two, two K pot. The two O and then the two represent the two O's. That's two K. I've looked at this one already. I'm not sure what's that. There's a 224 or something. Can't get it to 221. So that's 220. Yeah. So, all right. So this is, this is the next kid to build up two channels. And these I believe are going to be for the smaller channels. There's not the, not the T92, T92s of these. But for these, here we go. There should be four of these. Heat sunk onto the, onto the board. There must be generally a little bit of heat there. I'm not going to count everything and make sure it's everything. I'm just going to presume everything is there. And yeah, 51s. Yeah, so that's it then. This is, this is the next package. This is the next kit build. And then this saves me just having to like show you in the test video. Otherwise it would just be way too long. So yeah, never done this before. Never worked with these transistors. Never used, I should say. Are they going to miss it like this? Just make it nice and easy for my heat sinks to go on. And I'll see if I can find up some more information. If I can, I'll put it in this little space right here. And if I can't, we'll just get through to the end of the video. All right then, guys. Thanks for watching, if you got this far. And I hope you're tuning again for the test of this once I've built it up. Bye for now.
