Ken,
thanks for your suggestion, the power supply took care of the hum!!
The low pass still didn't work, but I traced the problem to a bad pad
on the pcb. This PCB had a few bad pads on it, but the others I
noticed while I was putting it together. All of the other PCB's Ive
gotten have been fine. Something must have gone wrong in the
manufacutre of this one.
Anyway, problems are all solved. This is a GREAT sounding filter!!
thanks so much
Scott
