Yet,  when I modulate the rig in regular conversation on the air, the 
receiving  station says my unwanted sideband is only about 2 S units (12 db 
?) lower  than my desired sideband.  Any words of advice?  


Do an alignment of the phasing setup, only a few trimmers to adjust.   As the 
tubes age this section of the transmitter needs a tune-up from time to  time. 
 And anytime the tubes are replaced or moved to a different socket  the 
alignment needs to be done.
