Hello
I wondering were i can found a pcb for two LM386 in stereo??
Ive found meny small electronic kits but they just got the scheme..

infinite info on lm386 on the web
search on google for the pcb of lm386 ,probably the worlds favourite low power audio amplifier.
u will find countless pcb for that amp that are not wrong and most (99.999999999%😀 )will work

stereo from mono
if u get a good mono pcb u can use it to get a stereo configuration, how??
just build two mono amps.stick cardboards to the solder side of the amp pcbs(after u have constructed the amp), and stick the both amps back to back from the cardboard side.since lm386 is flat n so r its most components(make the electros lie flat on the pcbs),,this method is useful to save space bec onle net thickness inc not the width.
connect thegnd wire of the input so u get three input wires with the input gnd wire being common
connect the power supply wires of both mono amps
now for the 'new' stereo amp u have three i/p wires,two power i/p wires and four audio output wires
i have used this method to save space in pre amp design using tlo72.the thickness increased but width was decreased drastically thus fitting the whole system in a small cube which gave me 'pre amp cube' and not the conventional 'sweets box' design style of most of the circuits.
rest as u wish

Hello
Ive searched around in about 2-3hours but cant find any stereo or mono PCB...plz show me what you found!

believe me. LM386's are not enough for those.
I have used a similar looking driver and they require a bit more power since they are inefficient. you need about a watt or two to make them loud enough. for a simple stereo amp you could try looking for LM1877. it is already a stereo amp in one 14pin DIP. I have used it (took it off a PC soundcard) and it works fine, not that loud though.
if you want, you could try a sonic impact. they will have more than enough power for those speakers.

Hello
Okey! thx for the tip...my lokal component shop got the LM1877 it wasnt so expencive...
But what is the sonic impact ?? were can i found some info about it?

the LM1877 requires only a few parts. building it is about the same as building an LM386. type "LM1877" in yahoo or google to look for its datasheet.
for the sonic impact, you can do a search around this forum. there are lots of info about it here.

But the sonic impact isnt a chip?!?
I think i build a amp from the LM1877 instead of buying the sonic impact...

lm386 is a great one.
u can make it to drive those speakers.
use four of them in bridge config. to get close to 1.5watts per channel.
give it a try bec that ic is really good one

this link takes u to jus one pcb.

its jus to show u that infinite pcbs available if u search patiently

Hej
But that pcb is for a weird speakertester...
Ive bought a LM386 today and tried to build it on a experiment board...but it wont work?!? as audiosource i had my mp3 player...do i have to build a preamplifier to??

i have a pcb
i have a full fledged schematics and pcb that worked.its from an indian magzine 'electronics for you'.
main prob is that i will have to scan it up whih i find !@#$%
tell me if u want it then i can give it to u

Yes i want the schematics and pcb !!
some time req
its night out here in INDIA (10:00) and i m in no mood to rush out for a scan.
sorry to say man but
i can get u that scanned latest by saturday
if u can then wait

see this link.the circuit i.e the audio mixer.the amplifier used there is lm386.

oh sure man
thats what i was sayin.
i will get the page scanned for you(i dont have it at home,will get it from market on sat)
i m too busy for all day long for all this but its a promise that when i m free i will scan n mail it to u🙂
