Mike,
It is hard to believe, but this reflector is a gold mine of information on
the R-390 receivers.  Unfortunately, as of late, the simplest question seems
to elicit hundreds of sophomoric responses.
The R-390's follow the standard Collins receiver electrical design.  The big
difference is the ingenious mechanical tracking.  You might want to try the
Collins reflectors for ideas on SS conversions.  ( I recall a SS 75A4 some
years ago)
Tube to SS conversions have not been too successful, but that is no reason
for not trying.  Good luck with your project and please keep the community
informed on your progress.
