[R-390] R-390A alignment..

[Pete Williams]

G'day all... I've done a few restorations but have a  query on a variation
not so obvious on alignment  procedure
The  4 - 8 Mhz rack. when fully  adjusted , ends up with the  slug tops
 almost level with the   rack ....... this is at variation with all the
others both past and present. The  adjacent rack  somewhat similar but not
 as bad..
I am aware of  cam  setting  and possible  trimmer/capacitor problems  and
 even incorrect  slugs, but this one  seems to defy convention !.
What I've  done is .... checked  cam settings--- even tried slightly
different position,.
Repositioned interrelationship of  trimmer settings with  core  settings
Changed slugs.
Installed a  new set of  coils.
RESULT.... all alignment same  as  before and  sensitivity OK..... I don't
like the  slugs being inserted so  far into the  coils--- doesn't  seem
right for me.
I've followed Roger R's  listings  over the  years   and maybe he might
have  an  explanation.
Thanks
