file: mosfet.txt updated November 2, 1992 Sources for dual-gate MOSFET devices RCA has discontinued their 40673 dual-gate MOSFETs. These devices have been used in QST and other ARRL projects for years. To help our readers and members we are compiling a list of sources for these devices or their equivalents. This list is quite incomplete, I just didn't want to make people wait until we get it all done -- it is one of many things on a large list of stuff to do. Updates, additions and corrections are actively sought! Send them to mtracy@arrl.org.
