I looked around online to find a circuit for the 386 that could give me the best sound quality to my mini subwoofer speakers, and found one in the data sheet. I copied it into eagle and changed a few things like adding a smoothing cap. and a pot so it could have two channels. I was just wondering if there are any changes that I could make that would improve sound quality or if i could change the two smaller caps, .033uf and .05uf to anything else, since I cannot seem to find them in my local Radioshack. And I was also wondering what type of cap to use as a bypass on pin 7. Thank you.
