I owned a Hunter 2000B.  One of its problems was that the plate
choke showed series resonance in or near both the 10 meter and
15 meter band.  I replaced the wire in the choke with a size
larger (From no. 24 to no. 22, as best I can remember) and the
series resonance moved above 10 meters.  My power out on 10 meters
jumped up from 600 watts to well over 1,000 watts.  I also changed
the biasing system by putting a 50 watt zener between ground and
the center tap on the filament transformer, as I recall.  It was
a humpin' machine for years thereafter.
