The unit I have quit working. I have tried to find the cause without luck so far. I can't figure out how the low voltage (5V dc) works or actually how it gets it's input voltage. The voltage regulator (LM78L05) does not get any input voltage (12V dc). When I apply 12V dc at the regulator it works fine and provides 5V dc, but still no sound!
Does anyone have a schematic or any info that may help fixing my unit?
Thanks
