Well I think the first thing is to check all of the sections of the tuning cap for shorts (plates rubbing). The general rule for alignment is adj trimmers for the high end of the band the coils w/slugs for the low end. If your set uses triodes for the rf amps it probably will have neutralizing caps too to adj.
