A positive attitude may not solve all your problems, but it will annoy enough
people to make it worth the
effort.

Hugh,
Yes, I double checked the model number twice since I couldn't find any
schematic listed. It uses a LA7838 for IC401. Pin 1 has aprox. 12vdc but I
find nil voltage on pin 8. Not sure what voltages to look for.
