I was able to fix my voltage problem by grounding the PCB to the chassis, DUH. I forgot I used insulated standoffs and that's where my problem was. The hum told me something was up but didn't think to check the voltage reading when I grounded the board. All is well now and sounding fine. If I can get a hold of a digital camera I'll post some pics. I will do some modding at some point but wanted to basically build stock to check for problems first.
