 Hello everybody, welcome back to my V-LOG, to my channel and today I'm going to do this sort of bit of an unboxing, the reason why I'm going to do it is because there's a bit of information on here that I want you to know about this particular item, why it's already in the description, this particular amplifier and it is one of those things You've got to be careful sometimes what you're buying and where you're getting it from, how am I going to get in this? Oh my God, the box has got me stung. Now this was a recommendation of somebody, somebody who I've only seen them on the Poppins channel and they said to me, hey have you tried this? It's got a really good really good output, you know, the distortion level is very low and it looks like a really good amplifier and they showed me a little bit of video and they showed a low distortion, it's a seedy pack, brilliant, reusable they showed me the distortion level and I thought, oh that looks pretty good in actual fact that competes with the L12-2, I say L12-2, that's what it's done, I don't know if there are any other L-style I like the way it's packed, nicely bubble wrap, oh nice, wow, alright so check in, I'm not sure it's the right board and you'll see why and I'll do that in a moment, that looks nice, just looking at the back no pandas on the back, no branding as such, oh what's this saying, it says here we got the X1 SYM 5-3 power amplifier, alright, and there we have it and so, oh it's got it written there as well that's nice, oh 2.2 microfarad to 10 microfarad on the inputs and what we got here, MJL 4382, MJL 4302, so the complimentary should be there, 4281 BD139, nice, MJ, wow, 150-33, they're not cheap, not cheap alright so let's just have a look at the parts, and they're not cheap, not if you buy them here anyway that's for sure, nice again, looking at the backs of the transistors, how nice and clean they are I do like it when you get transistors, they're not looking like they've been left outside for however long and they say Nichecon on them, wow they do, they say Nichecon, alright, they're all kind of me impressed kind of me impressed, we've got a whole bunch of these here, really so these are different colour, that's what I expected because when I show you the thing, these all say Nichecon and I've got no reason to believe that they're not we'll stick them in the SR meter and have a look, I might do that on the actual build these are nice as well, so our higher wattage resistors, they're all 1% or at least they're metal types that means that we can adjust the bias, ah sorry the bias, the cliescent current, I'm hoping the curls are nice, they don't look deformed or anything like that now this is something that I was interested in, because they said that these would be Weemur and they are Weemur the 3.3 micro farads, these ones don't look like they're Weemur, because Weemur have them stamped on there generally but still, no that's all good, we've only got a couple of these little things, I'm not really liking these Ceramics but it might depend where it goes, it could just be for, I don't know, stabilising some oscillation and then we've got a whole bunch of resistors, they do look like, you can see the colour bands on them nicely I've had resistors before where the colour bands looked broken up and all sorts, not very good but to be honest I'm quite impressed with these transistors so far, these are the BD I've got to take these out, just because I've got to have a look, I've got to have a look and this is going to be then, be through my light down and look, right that's a C4793 that isn't an MGE 15032, that's for sure, that's another one of those no, that's an A1837, so some of this is going to be 139, yeah I don't know about those these are different as well to what they're supposed to be, this is a Toshiba TTC5200 it says Japan on there and stuff, so that's quite warming but it's not what it says on these look those are nice and heavy, I do like that, that's nice and heavy so there are a little bit of differences as to what's going on here one of these will be the Philips, 2N5401, 551, these look like they've just been pulled out cheap perks, there's 54, 546, BC546, I'm sure I've got some proper Philips one of these, so yeah some of these transistors are different alright but then again, so are the capacitors let's look at the screen, let's get off this a bit, I'll take a peek at the screen now this is what I want to show you first, because if you were going to go and buy this because I said hey this Syma SIM 5-3 power amplifier, 2x100W which would be this that I'd be talking to you about is good because we've put it on the meter and everything so I found one, what I tell you now is that this is not it is saying that, that's what it is, but it's not what it is and it's cheaper than what I paid for it finished board £37 there look and you would be wondering to yourself is that the same and I'll tell you now, the description and we're going to go on this PCB specification, 180, 69, 1.6 which is what this is, that's the size of this but as you can see here it's 138, oops, 138 by 50 so there's differences so far now the bit that I'm a bit not talking about is because you look down at specifications and you think look at this one distortion, THD, not THD noise but THD, 0.002% into 1 kilohertz at full power my cat is deciding to go investigating into a box but I shut up because it's got other boxes and stuff and they're going to go out and recycle a bit and he's like now he's going to start picking all that apart excellent and then that's a 1 kilohertz full power and THD is 0.005% into 10 kilohertz full power so that sounds pretty darn good, right? and yeah, you can see where here it says about the outputs and stuff there while it says on here, slightly yeah, but never mind, right so all that description is basically just copied and pasted from this one, which is exactly the same written here as what's on the other screen this is what I bought so we've got two times the amount of power, yeah and it's the same board and this is what we're going to have, I told you that the capacitors are different colour look, they're Nichi Khan, these are whatever these are but all this other stuff is, you know pretty much basically the same so just be careful, if you did go off this, if we did when we do this, and if it does turn out to be pretty good and it's a single board layout, so you've got a nice big heatsink for it that 200 watts being put out on the big heatsink you're going to make sure that you've got a good heatsink for it or radiator yeah, on here they're fippings here, dual channel, 100 watt per channel so just be careful just be careful, I just thought I'd put that out because I think it's worth saying and now what I'm going to do is build this thing up and we're going to test it I may not be able to get it done today because I have a visit coming around very very shortly and I know that they want to try and drink, but I will be looking these up and just comparing them against what's here because these are supposed to be good for 250 volts and they need it, and what's written here what's written here, because I've already looked them up 15 amp between the collector and the meters so we know there's a nice big swing and actually pretty good like I say, I'm one of the amps I've built which is from the ESP website and I did the whole thing myself on Perfboard that can use one MGE 15032 they're not cheap they're not cheap but again they're 150 volts these are for the drivers you see and anyway these are for the drivers and they're not cheap so it's going to be interesting interesting little build, put it together see what it does, see what it sounds like but we're looking at it mathematically first thanks for watching and I will catch you in the next one bye bye for now
