Refer: Silicon Chip February1994 This tiny module uses the LM386 audio IC, and will deliver 0.5W into 8 ohms from a 9 volt supply making it ideal for all those basic audio projects. It features variable gain, will happily run from 4-12VDC and is smaller than a 9 volt battery, allowing it to fit into the tightest of spaces. PCB and all electronic components included.

Radio?
this amp has worked well for me and I still love it but whenever I run it from an interference free source like a 9v battery it is very quietly playing the 97.3 The Sound radio station?!? this is not from interference from my house it is picking up the radio signal. I beleive this is due to the ani high freq ocilation ciruit getting the radio signal and cutting out the wave that is encoded in and leaving behind the audio. this is a very bizzare and unexpected thing to have happend.
sounds great!
I just got this kit It works great and is a pleasure to make and sounds amazing when connected to proper drivers
Stays good for years
Bought this a couple of years ago, still holds up pretty well.
