How does it stack up to the JFET design being discussed? Also, I'm visually oriented; finding it hard to follow the JFET discussion. Any pointer to a schematic of an implementation? _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
