Fred,
This is an audio output chip. When I am confronted with a situation like
this I look to the B&D site for a spec sheet on the chip. Without a
schematic it at least gives me what I need to check that chip and the
related parts. They have thousands of specs for chips used in consumer
electronics, including this one, which I downloaded recently.
