[R-390] Bypass capacitors, R390 and SP-600 [WAS: saga continues...]

[Cecil Acuff]

Yes and no....

The paper caps in the SP-600 were the worst/  The R-390A's were better but 
not tremendously better...based on what I have seen through here.  The 
R-390/URR is a whole different animal.  Quality caps throughout.  I've never 
had to replace but a few over the years. Much more reliable radio in several 
ways.  Manage the heat and they will run forever I would guess.

I do NOT see the need to shotgun 390s or 390As, except for the
several critical and failure-prone caps -- they do not have the same
record of unreliability as SP-600s.
