Hey SCA,
I've finished assembling my pre amp but it does not pass any signal. I've rechecked it and all resistors and ICs are in the right position, and diodes and capacitors are set at the right polar pattern. Signal flow seems to be good. The only problem that I can tell now is that R3 and R4 now have a value of 3K66, but i checked all the resistors as I put them on the board so I don't think its the resistors themselves.
Can you think of what might be the problem? Maybe a problem with power reaching the preamp?
