[R-390] Oldham Connector piece needed plus deaf band question

[Andy Vavra]

Hello to the group.  I am restoring an R-392, little cousin to the R-390
series and am in need of the small piece of plastic material that goes
between the two halves of an Oldham connector to join the bandwidth shaft to
its switch assembly in the IF strip.  

 

Does anyone have one to donate or sell?  

 

And my question for the group is this:  The receiver is slightly hard of
hearing on the bands between 7 - 16 mHz.  Crystal oscillator is strong as
measured at the diode load jack and other bands perform well.  I figure the
common genealogy between the 390 and 392 should share some common problems
and fixes as well.   Is this a sign of an alignment issue in the RF deck or
something else?
