[TV MAN]

I think I got it. I'm not 100% sure what I did, but it seems a lot quieter now. If I put my ear to the speaker or use headphones I can still hear a little hum, but it isn't notable now in a normal setting. I know any amp will have some low hum with your ear up to the speaker, so I'm not too concerned about this one. It doesn't have a choke or anything and it isn't a Fisher or McIntosh. It IS quieter now. I did remove that extra ground, didn't notice a huge difference either way, so I left it out. I did resolder the grounds near the bridge. I also tried clipping the jumper mentioned and grounding the cap neg to the chassis, but didn't notice any change so I put it back. Anyway, I'm going to put the cover back on and do a serious burn in and try some different preamps like a Dyna PAT, speakers and such and try to see how it really sounds. Other than a few bugs (thanks guys for the help) it may not be a bad little desktop or home theater amp. I'll update after pushing it it a little harder. Wife's asleep and I want to keep it that way for tonight.
