Thanks for the info and advice Pete. I recently saw a comment that
standard 1N4002 type (60 Hz) diodes are actually good replacements for
the PIN diodes on the front-end band pass switching networks. Have you
heard of this?
Whatever happened to all those Schottky Diode mods that seemed to be the rage
years ago? Would this be something similar?
That is a standard silicon power supply diode with something like .6 -
..7 volts forward voltage drop. The Schottky would be at least half that
and many are more like .25 volt.
If you don't bias the diodes into their linear range then it takes
signal power just to turn them on/off and that's where some of the
distortion comes from and the non-linear area contributes as well so the
smaller Schottky is an advantage.
