I'll check around my local recycling salvage next time I take my trash that way (I usually use the dump nearer my work which doesn't take any electronics) see what I can find. Thanks for that link that's a very interesting read and a useful couple of curcuit definately bookmark material there. If I mimic the process that guy took with a couple steps I could potentially turn what I have into a more permanent solution. My original intent was to salvage or buy a 24v or higher transformer eventually and build a power supply for it but maybe I'll skip that step.
That lm1875 looks like the best option I've looked at so far I'll probably tack a few on to my next order to experiment with.
After looking overy my breadboard I found a couple capacitors that were way off replacing them cut actually quite a bit of the higher pitch whine and even some buzz. as long as there is notes coming through the speaker it sounds good just the silence isn't totally silent
I also tried running it using 2 9v batteries connected in series to make 18v it had about the same amount or buzziness either way I don't know if that means much. If I put my hand pretty close over the curcuit I can cut the static-y kind of hissy bits of the noise down to where it's a pretty dull even hum I assume that's basically a preview of what I can expect to change when it's mounted in a grounded chassis? I don't know maybe not
Another thing I'm starting to wonder is how much noise is coming from my cheap (and pretty far from new) cables or the amp I'm hooking up to or even my guitar that my be the next test I make.
Anyway thanks for the help and interest I'll come back with any updates
