i made an lm386 audio amp with 200 gain and hooked it up for use with an iPod and an optional mic. the circuit worked fine on the breadboard but when i soldered it, it got cranky and started oscillating (i think that there is some feed back)
the only differences are that on the breadboard R3 was 200Ω, R5 and R6 were replaced with a 100Ω pot.
on the soldered board C3 was 330µF. and all of the components were really close together.
i need to get this circuit working so i can start selling it for my next project.
