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. -- Telamon Ventura, California |
