I replaced the plate choke in mine with an AL80B choke purchased from Ameritron
for about $25.  The original plate choke had a resonance near 17 meters.  I
added a corona washer to the bandswitch lug that goes to the hot side of the
160-meter padder capacitor (I also had to replace the contact which was burned;
I never had a reoccurrence of this).  Be sure to check the value of the carbon
resistor in the parasitic suppressor!  I also added a vacuum relay and reed
relay for QSK (got the kit from Rich and the v. relay from Alan Bond).
