I built this ab763 preamp into a stompbox with an added DI output. When using the DI out there's a lot of noise (like wind blowing). I measured the opamp and I get 4.5v pretty much on all pins except pin 4 (0v) and pin 8 (9v). I tried replacing the Opamp but no go.
Would that be a busted cap that is not filtering DC?
Any help would be greatly appreciated.
Thanks
Sorry, now the correct schem is attached...
