The pots for gain/volume were a little scratchy when adjusted but not bad - then 1 day - poof no sound!
I changed the input jack, no fix. I changed the volume pot and gain 1 - no change - but while I was holding the circuit board in my hands a radio station started coming through the speakers/headphones - my thumb was obviously bridging something on the circuit board - but it was over the volume and gain pot area so this leads me to believe that the problem is still somewhere between the input jack and its entry into the circuit - any ideas?
When I turn the pots the sound is getting from the pots to the headphone jack (speaker disconnected as electronics are out of cabinet) but still nothing from input to pots as far as I can tell.
