[R-390] 390A audio

[Cecil Acuff]

I think a good start on a lot of your questions would be to take a look at 
this site. http://www.r-390a.net/Pearls/index.htm  It is a collective work 
of significant stuff about the R-390A divided into categories for easy 
access.  Better than having to search the archives.

Also to answer your question that is done by many....something like a .1mfd 
cap and a good amp and speaker and you have much improved audio.
