Found one of the sources of my problems.. I was using Connect to nets by Name instead of Connect Net to Pins By Name for the GND net. this was causing anything connected to GND to be part of that, so when updating the PCB, several components were grounded that should not have been. After combing over the schematic about 20349032 times, I think i've fixed all my goofs and have a PCB layout that may work. I used the schematic and threw it on breadboard and it sounds great.. compared it to the clone version I built and it's sounds very similar (a little noisier due to wires and shielding but I expected that).
so I THINK/HOPE the updated PCB layout from my schematic is correct. I did my best to compare mine to the actual PCB and all traces appear to be correct..
I have learned a great deal in the last few days all thanks to everyone on this thread (and members on other threads!!) Immense thank you!!
