[R-390] R-390 mods and weak points

[Robert Newberry]

I've been reading various websites and archived threads. I have a non A
R-390 that is all torn down to individual modules. My questions are.

Is there any caps or resistors that should be checked or replaced? I've
read alot about "death caps" and 47 ohm resistors but everyone was talking
about R-390A.

Are there any recommended mods? For example I've read about fatting up caps
in the audio module to get more low end audio. Although these were
referenced to the R-390A. I'm all set with the inrush mod for slower start
up and hanging a fan to aid with cooling.

Thank you
