[R-390] If those Capacitors could talk

[rbethman]

  Cecil,

I have NO false illusions!

I treated a '67 EAC with the SAME viewpoint!

I checked and replaced MANY resistors and caps!

Also found the "infamous" acid electrolytic on the Audio Board!  Checked 
and replaced resistors there and throughout the entirety!

These ISSUES apply to ALL of these radios!
