The output power of a single LM386 amplifier at clipping into 8 ohms with a 6V supply is 0.2W. The output power of a single LM386 amplifier at clipping into 8 ohms with an 8.2V supply is double at 0.4W. Simply increase the supply voltage for more output power but above a 9V supply the output power barely increases but the heating increases a lot.would it work to put 2 LM386 amps in series to get double the output?
You don't show a supply voltage so I guess it is 9V and then its output at clipping is only 0.45W.i built this circuit as an acoustic guitar amp for a friend. it works well, but he wanted it to be about 2 to 3 times louder.
