Hi folks,
I have a 2 channel microphone preamp that no longer receives signal from the input jack. Neither channel works anymore. The unit does power on, but no audio goes in or out. I am a total novice to electronics. I know kinda how to solder and I have changed pickups in my guitar before. I think I may have found some bad capacitors in the circuit board, but I'm not sure. I could just be seeing adhesive. Here's some pictures.
The first 2 pictures are capacitors from both sides of the board. I assume 1 for each channel. The third is a reference image to show a healthier looking capacitor on the board. Not sure if the brown stuff is guts from the blue cap leaking out, or if its just adhesive. The last picture is a chip on the board that has some shiny stuff around it. Again I'm not sure if that's just normal adhesive or if it's a problem. Those were the only visually suspect things I could find on the board.
Any input would be appreciated!
