[AMPS] 50MHz 8877 amp. plate circuit (score: 1): Author: philk5pc@tyler.net (Phil Clements); Date: Mon, 8 May 2000 12:55:54 -0500; Hi Chris, Duplicate the design at http://user.super.net.uk/~equinox/8877.html I have used this design several times, and it worked every time. The plate choke is very critical here...that may be mess; /archives//html/Amps/2000-05/msg00107.html (7,694 bytes)
