Attached are three screen shots from my oscope there is one that shows no input in fact this is what I get with the input shorted to ground. The other two show the output at a low level and then the output at a moderate level. At a high level it gets very ugly. Not sure what I am seeing. I expected to see something that resembled a sine wave.
