The Apex radio that is finally playing now is only picking up signals from 1200 and up. The condencer plates were making contact thus no reception at all when I got the set going again but with some adjustng by loosening screws and gently moving the plates it helped the reception to where it is now. Any suggestions would be appreciated.

Since its working from 1200 up....which would be with
the caps plates mostly unmeshed...right sure you got
all the "shorts " out ? Easily verifiable with an
ohmmeter from between the rotor/stator elements, con
sidering no circuitry coil is shunting them...if so
disconnect before trying your testing.
Also considering none of that "screw loosening" didn't
include paddding capacitor adjustments.
Usually the vanes that get bent/ displaced are the outer ones on the cap banks rotors.

F.I.O. in olden times when I would have a REAL problem
finding the shorting/scraping culprit I would be sure
that the offending cap bank had its stator section
floating from circuitry and then take an adj bench
supply and set it at a few (3-6) volts DC and then
connect across the caps rotor(Gnd/frame ?) and the
stator. I would purposefully then bend in an outer
test leaf to drag just a little. Observation in a dark
room then lets you see a slight arcing at the point of
contact IF the P/S was set hi enough. A flashlight
flicked on at the moment of detection lets you see the
specific problem point. Next tension the test vane into
a proper/ centered alignment. After the test vane is
corrected move on to isolate the real problem vane(s).

After studying each section of the tuning cond. I notice the vanes on the rotating shaft are pushed out from the center of each section possibly due to presence of cracks in the material that bond the rotating vanes to the shaft (potmetal??). Nothing seems to be bent as far as the vanes are concerned they are very much parallel any minute adjustment left or right is not making any difference.
