 There you guys click a little share on this This here is a very crude it's a LM 1875 and It's taken directly from the data sheet That's the schematic I didn't have a 200k resistor game between 4 and 2 so I put a 220 there But everything else is pretty much Everything else is as it is there on the date sheet And just to show that it can be set to a sort of pretty crudely I've only got one channel I've already got one channel on this that actually works. I just turn off the night It doesn't sound too bad. I don't have any Any any heatsink on there, so I'm not gonna It's not getting warmer or anything, but I'm not gonna push it. Oh, yeah Just to show that I'm gonna look at that look a mess that is Bloody wires all over place I Don't have actually I don't have any music on my phone because the headphones suck. It's broken It only works in mono so I've been actually playing the music from then. I've just got like a mono connection going in Going into there onto that one make But as you can see it's it's very very crude it's just chucked together in that socket board But it goes to show that you know you can get these things to work and work reasonably okay Even if and it's not using a So using a single supply that So we've not got a negative voltage on there, and I'm just Taking that already off here 10 and a half volts basically And it works So if anybody out there was thinking oh, I don't know about setting up one of these LM 1875 Do it. It's just taking me about half an hour. Just chuck these together something longer to find the parts I Pretty simple I Have actually brought all of the earth's down All the grounds come down to this this part here like if it was in a star ground fashion and then the positive connection just comes in there so it's It's it's terribly set up But then it's not too terrible. It could be worse, you know, I could be having Lots of different connections for ground on this and it wouldn't be happy at all from my understand From the other the setups that I've seen are much better in this I've had this chip for quite a while and didn't think I'd be able to set it up It seemed a little bit too strict and complicated And it just goes to show that it does work and it doesn't I can't hear I couldn't hear any distortion on it No, the radio signal coming in through here isn't very good because it's supposed to have headphones on and that's a little bit of wire I've got as an aerial So I'm quite happy that it worked at all without making lots of horrible noise or You know having some sort of a motorboat type effect going on Anyway, I believe that would have been down to a dodgy capacitor I'm not sure completely And that's why I've sort of got a bit of an understanding of So anyway There we go LM 1875 crude and rude, but it works I'll do another one. I'll set one up better and do another one at some stage But I just thought I'd have a little play with that and see if I could get it to work And I'll use some very basic parts like so you can see on the schematic of your rewind back And and it does work. So you can get a bit of instant satisfaction Anyway Cheers watching
