 So guys,  heres a double fix-  Don sends me a rack with green slugs,  so  I can  fix the 390A I stole the slugs from.  OK-fine.  So now I go back to the Collins 390A which has a poor sensitivity problem on 1 to 2mc.  I try to make the peak adjustment, and I see that 2 of the slugs are  cut off and sitting at the bottom of the coils.  I had just pulled  the 2 red ones  from the original project that were incorrect.  Got  myself a magnet and pulled the cutoff slugs out of the Collins,  put in the 2 from  the Motorola,  did the alignment  and now running BC band with real good sensitivity.  That's what I call a double fix!  Got  to get lucky once in a while-hi!  73s Russ. [thanks again Don!]
