I used the LM386-one and looking out to switch it to the LM386-three. Only negative matter is when I hook up the bass Enhance that there is a number of dB reduction. I also would like to add an FM radio on it. Has a person an circuit for this? https://audio-amplifier-hearthsto49481.get-blogging.com/23956649/details-fiction-and-player-cd-estate-prato-fiorito
