Craig radio powers on, but no sound...
My Craig is out of the car and I connected it to a power source and a speaker to test it out. It powers on, the display works fine and all the buttons work, but I can't get any sound from the unit. For full disclosure, all fault lies with me and not the Craig, because sometime last year I (like a dumbass) hooked up the unit to a car battery with + and - backwards which I'm guessing probably fried the internal amp. When it happened, I heard a small pop, smelled some burning and then there was no power from the unit. Before this happened last year, the unit worked fine and had sound. Since then, I replaced some of the caps and soldered in new wires and now the display works fine again, but I don't hear any audio.
Has anybody had this exact issue before and fixed it, and could point me down the right path as far as what to look for/replace? I'm hoping it's a simple case of removing a small part and soldering in a new one. Any help is appreciated, thanks.
