[R-390] R-390A "Dial" Problem

[DJED1 at aol.com]

It does sound like the first crystal oscillator is off.  I would first  check 
the frequency of the oscillator to confirm that it is the problem.   Then you 
have a couple of choices: replace the crystal, or jigger the dial until  all 
bands are within range of the zero adjustment.  Obviously, the first is  the 
right way to solve the problem, but it may be hard to find a good  crystal.  
The second way may be adequate for practical purposes.  I  think the R-390 FAQ 
page does have a reference to the crystal specs.
