[R-390] Relative reliability of various capacitors? BFO Question.

[Phil Atchley]

Hi. =20

Today I took a "peek" under the IF deck  (EAC S/N 9653) to see what evil
critters might be lurking in there.  A couple pleasant surprises.  =
FIRST,
there are only TWO BBoD's (brown beauties of death) lurking in the IF
amplifier.  "Most" of the other capacitors are yellow Aerovox units with =
a
scattering of West-Cap metal/glass capacitors.  The FIRST thing I did =
was
replace the mechanical filter coupling capacitor (West-Cap) with a =
630VDC
jobbie and will naturally replace the two BBoD's. =20

Question:  What is the relative reliability of the Yellow Aerovox units =
as
well as the remaining West-Cap Metal/glass jobs?  I DID notice most of =
the
Aerovox caps are rated 200 Volts where I tend to use 630 Volt capacitors
where they fit. =20

If the rest of the receiver follows this pattern it may not be a =
terribly
tough job to overhaul.  I did notice that the IF amplifier appears to be
VIRGIN underneath the chassis!

NOTE:  The BFO in this unit is a unit made by some company called F & W =
Inc.
Anybody ever heard of them?   =20
