 hello everybody and welcome back to my video log here now this is gonna be a short video and it's basically just to say that having this connector has all been well and good but what I noticed was when I connected up using this circuit one of the 60 watts into 8 ohms 100 watts into 4 ohm circuits I got a lot of bang crackle moving around the input connectors which I shouldn't have been doing while it was on and what it ended up doing was popping out one of the drivers transistors here and that in turn shorted the other transistor and when that happened unfortunately I didn't notice it straight away one it blew up well didn't blow up but it made this the capacitor here is one of these it made it pop up thought I had it here for a second but I may have thrown it now never mind I know it isn't here it is made it pop up you can see the way the top of that is swollen up there and there's a 220 ohm resistor supposed to come off the the base of this and go to ground and it also killed that turned into dust pretty much but the worst thing is this is dead easy for me to you know fix up again not a problem the worst thing that it did was one of my speakers and I show you it's down here speaker there and the other pair is at the back there but what it did was it actually killed off this cone it's not smell a vision so I can't let you smell it but it does smell or burnt out and connected so I've got to get another one of these in order for me to fix that unit and so what did I learn from it well I learned I learned now I've got to be careful especially when things are plugged in and going and this is pretty high gain I mean you get 15 volts out of this thing so it's pretty high gain and that with tough connections you know crackling connections isn't any good for these are not the genuine you know these are just bought off eBay so you know what I found with some of the base stuff is like you were the LM 1875s genuinely and I'm 1875s got short circuit protection stuff like that the ones don't maybe because that's their paint and t-d I don't know but what I've decided to do is employ some bits of kit like this now this is a speaker protector and unlike some of the other speaker protectors I was looking at which is quite a few this one doesn't require its own voltage so it works on its own and it basically goes these are threshold voltages so if DC were to come through this what it does is it looks out for DC and this capacitor will charge up in it when there's a DC state going on and that will cause these two transistors like a dyac which in turn will turn on the triac and that will then short out the connection of the speakers you see this is credit for this or anything this is Brian Powell audio you can buy these online I'm not gonna say we've got a buyer money tonight I'm just saying that because I play around with this stuff I'm glad I've picked up two of these there's another one in there left and right channel of course doesn't need its own independent power supply and it should by rights hopefully in most fault conditions use this triac to basically short my speakers so they don't have a circuit running through them which is what happened in the instance that we're talking about here and that will carry on until the voltage drops below 1 volts or that this little glass fire up fuse blows now it's a pretty good setup from what I can tell and it should not make any difference whatsoever to the sound going to the speakers because this is a very low million situation but this is what I'm going to do now in order to rectify that I'm still waiting to try and see if I can get a cone I'm not going to lie to you I'm one of the types of people I had to replace my speakers so I bought myself some of those then monitor audio they're not very expensive really I've got them in a bit of a sale and you know they're all right they give me a much better bass I mean if you know the standard bass guitar is 41 Hertz on its lowest note so the speakers that time the speakers that are there now they go down to 35 Hertz so I've been listening to some lovely some lovely audio there but yes that's it just a real short video about that a bit of a boo boo there and I'll get myself back into gear over the next few days getting more videos but together that's it that's it if you worry about your speakers we've had them pop out before these are not particularly that expensive but I've got a funny feeling they are going to be a very a very practical and worthwhile addition to my little setup if I'm going to be playing around with stuff like this okay guys thanks for watching catch you in the next one
