Hey thanks for all the help, I'm not sure you understood what I meant about the RC network. This would be a 1ohm resister in series with a .47uf capacitor, this is placed from V+ to ground after the large capacitor to help bring down the inductance, I got this idea from tnt audio Ill give you the link. I'm not sure if it will help with the type of power supply im using, but its worth a shot. I'm still getting a sort of high pitched buzzing type sound from the speakers when no music is playing and I put my ear close to the speaker. Its quite low and you don't hear it when the music is playing, but id like to get rid of it if I can. It doesn't get louder when I turn the volume up it always stays the same level???
I have a bunch of parts laying around not being used that i can experiment with. I have a few more of the 10000uf/63v BHX Aerovox capacitors that I used, I can try adding another for a total of 20000uf and see how it works out, I'm not to sure the PC power supply will like that on startup though, but its worth a shot. I also have a bag of capacitors with lots of smaller Panasonic FC, Cerafine and Oscons. I could try building a bank of smaller capacitors instead of one or two 10000uf. Ive found that a few smaller caps paralleled sounds better then a single large cap, so its worth a shot. Im really doing this mostly for the learning experience and fun, I wasn't even expecting it to sound as good as it did:) Thanks alot for your help.
