LM386 audio amp on a chip. Rat Shack used to carry them for a few bucks. Probably available at most component shops.

Kevin,

    This is perfect.  I have only one more question.  What is the component labeled 386.  I would expect it to be an op-amp or something along that line.  What is the actual part number that I would need to look for.

Thanks again...  the folks on this list came through as always

Steaven, W4YI
