Hi Ken - yeh tried the mod and voila all problems solved. You wrote
Cut the track between Pin 5 of the TL072 in the bottom right corner.
Jumper pin 5 to the Saw AC output terminal via a 100k
I just used a jumper - is the 100k necessary between the saw AC output and pin 5 - it is not on the schematic. I have not checked it with a scope yet but it sounds ok without the 100k
thanks for looking into it.
cheers
Mike
