Thanks to Paul, WD7S, my problem has been solved. Paul kindly analyzed the original schematic of the amp and my conversion and determined that a wiring error in employing the W4ZT bias board had resulted in creation of a grid metering circuit instead of a plate metering circuit. 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.
