FWIW:  What I've been doing here is this:  I picked up an Icom R70 receiver for under $200 - 100khz to 30Mhz coverage.  Tune it to 455khz and connect it to the R390A IF output jack.  I then use the R70 with USB/LSB modes, noise blanker, passband tuning, notch filter, RIT, AGC and the R70 audio section with the R70 speaker, or an external speaker, to listen to SSB.  Seems pretty simple and it works.  No changes necessary to the R390A.
 
By just tuning the R70 to 500Khz I can also use it on the IF output of my R388 for SSB.
 
Maybe ignorance is bliss?
 
BTW:  Merry Christmas! to everybody on the R390A reflector.

Thank you for all of the idea's!!

  I have a 1958 Motorola R-390A scattered all over my shop in the 
process of being restored.  I started putting the RF deck back together 
today.  I'll report back which direction I have embarked on 73, Tom, N3LLL
