[R-390] IF deck question

[rbethman@comcast.net]

Okay guys,

    I have an older R-390A, a 1952 Collins contract, S/N 252.  The IF deck
is S/N 35.  It was only brought up to "MOD 1".  It has no variable
capacitors to tweak the filters into line.

    1)  Should I leave it that way and just take my chances with the filter
alignment?

    2)  Or should I try and scare up eight of the buggers and modify it so
that I can bring them right in on the money?

    3) If the latter, does anyone have a source of these critters?

    I'm ready to start bringing it back to life, and want to lay out the
course of events.

    (Now if I can only find L501 that I scrounged to replace the one with
the broken slug.... Where oh where did I put that thing.........)
