What happen if 191k & 30k Res removed from lm386?
« on: December 02, 2008, 02:42:49 AM »
I've done this mod, but the sound reactive isn't that good, you know, not that reactive..

I was thinking if I modiv the resistor value, I can get better reactive, even remove it..

Anyone know these things?

Any solution?

resistors limit current. im not sure where those resistors go, but if your thinking about removing the one from the LED's id suggest against it as they may burn out.

try using the right speaker pinouts or lowering ur resistors experiment
i would if i had money but i don't just go to radioshack and buy that pack of random resistors start by lowering it lil by lil 150k and 25k or something like that or lower one keep the other the same i would start wit the 191k lower it lil by lil i heard somewhere 100 is good but idk  never tried it up to u
but there is a high chance ur leds will burn out if u go to low
GOOD LUCK  :tup:
