1) IC sockets are not "bad" if you use good Augat screw-machine ones. If you
want to see
what happens when you use cheapo "leaf beam" sockets, ask Steve Jobs about
the Apple III.
2) Bill's point is well taken. The '420 filter, and the upcoming '410 are
sensitive to the driving
signals. One the '410, I will have the option of adding a -6dB pad on the
front end (you provide the
resistor).
