Everything seems to be working fine except for one small problem. I added the second channel by duplicating the circuit. Since I used a 470uf cap as a filter on the first circuit, i added a jumper below the positive cap lead to the second amp circuit, but still used a second .1uf cap as a second filter. When I turned the amp on, the speaker barely moved, which was good, however the first amp still pulled the speaker in. ~2.5 volts were running down the output wires on the first amp, but my meter barely twitched on the second amp. As the second amp started to overheat, I gave it it's own 470uf cap, but then the speaker pulled in when I turned it on. Would it be better to have a large cap right across the leads of the female connector barrel plug? I saw a few comments on another forum of someone using a 4700uf filter cap. I was thinking of using a 1000uf cap, since that was the closest value I had to replace the 2X470uf caps. Thanks for the help, this will hopefully be one of the last comments on this thread.
