[Collins] 51J parts

[Bill Kirkland]

I've sent Ed the part.  The coil forms are tricky because they belong to a 
sub-assembly
which includes the tuning trim cap.  They are mounted as a package in the RF 
section.
It would need to have identical characteristics as the other two coil forms 
used in the
RF deck for that band grouping so that they all track together as the 51J is 
tuned
either across the band or as the band switch is changed.

If folks are interested, I can remove an another sub-assembly and photograph 
it.

I didn't check the winding on L105 but I do know that the windings on some 
of the
coil forms connected to the IF tuning rack are not uniformly spaced wound.
