And no more 60Hz hum from feeding the bias thru the filament xfmr CT. vy 73, Bryan WA7PRC ---------------------------------------------------------------------- Date: Thu, 24 Apr 2014 19:50:07 -0400 From: Bill VE3NH Subject: [Amps] WEIRD ONE SOLVED The negative lead of the bias board should have been grounded instead of attaching to B- since the GI7-B has an indirectly heated cathode whose pin is common to one side of the filament. Bottom line: everything now works as it should. Now, bring on the 6M DX! Thanks again, Paul.
