I have now looked through the layout. Took the schem and noticed every component and conection. "Unfortunately" I can´t find any other errors.. (except the 1M to V+ and the fliped 47u) I think the flipped cap is strange. (Plus to ground and minus to +4,5V?) That cap can´t feel verry good? Or am I missing something in electronic knowledge that explain it?
Well, give me a hint when you´ve squeezed in the 1M! maybe thats the "only" problem.
I wouldn´t flip the cap before I tested the circuit with the 1M in place. To my knowledge-level that has to be a culprit in the schem.
