filter and amplify


note these words in the description of the amp shown in your given link.filter means that the circuit will attenuate common signals out(music in your case and noise in his case) and will conc. only on reproducing the hum of a bug.so it might b possible that this is the reason for tweening sound in your amp

did u find anything useful in links i sent u??

if yes then go ahead else wait for monday when i will get my mag back.

i will post it for u out here asap on monday

:hot: gentleman's promise:angel:

thanks that diyforum exist in the world(virtual at that)
 
hey slowfly
i wonder y the circuit didnt work!!
change the circuit parameter by inserting a resistance of 4k7 b/w pin 8 and c1.that may help.

i suppose u have built two circuits now but to no avail.
so check the i/p signal source . is it mono stereo.
see your earphones that u got with it.is the earphone powered?i.e wether there is any indicator light,lcd display etc etc?

better test the circuits u made with the output from a computer(most reliable signal source).if it works out then fiddle with your player o/p.but thats a different story.test with comp. first
 
Hi Slowfly,

Here is my schem for the amp, I built it years ago, and it is still running almost everyday at my dads office. 🙂


Nordic, where are you from? I see you have a RSA flag. I'm from Jo'Burg. It was raining the whole night yesterday. 🙂

Anyway, Slowfly, let me know what you think/happens? I'll post a pcb later. :devilr:

Cheers for now,

Werner
