[R-390] filter trimmer access holes

[ka9egw at britewerkz.com]

Thank you!

I note Chuck's statement "...the IF deck needs to be loose but still
electrically connected..."

If I zap 4 holes in the sideplate in the right places then I'll be able to
set those trimmers without juggling a loose, live subchassis.

I wonder if later production units had the sideplate ventilated, or if the
filter trimmer adjustments were done strictly at the depot level?

Alignment..\\Includes how to get to and adjust those trimmers on the side of
the IF deck.

My IF deck has the filter trimmers; MOD2 I think this is.  The chassis
doesn't have access holes to get to the trimmers...the IF deck subchassis
does but the main frame sideplate covers them.

Has anyone here ever generated a print of where the holes in the sideplate
should be?
