I don't know about the R-390 - always rack mounted those we 
had - I had always assumed (there is that dangerous word!) 
that the cabinets would be the same as for the R-391s.

Sherry's R-391 is in (best we can tell) a CY-979/URR...  
which is the single "Mobile table-top"  cabinet called for 
in the manual.  The manual also lists the CY 917/URR for 
"desk-top" use.  Then goes on to also list the CY1119/FRR 
rack (i.e. AN/FRR-39) --  and the CY-1216/U - but I'd always 
thought of those used with the R-388s (i.e. AN/GRC-26).  The 
book says to remove the top and bottom dust covers when in 
the CY-1119/FRR cabinet; but interestingly enough does not 
mention that with the other cabinets (each cabinet has a 
paragraph).  Even so, I'd think it prudent to pull the 
covers - and in the case of the R-390/1 a small fan wouldn't 
be overkill.

best!
