[R-390] Replacement Caps

[Fraser Bonnett]

OK, so I screwed up my courage (let's hope that's all I screw up!) and
removed the IF deck from my R-390A, with the intention of replacing C553,
C547 etc (basically the ones usually identified as problem caps)

The problem caps seem to be Sprague Vitamin Q's, which I intend replacing
with Orangedrops.  However, there are a bunch of other caps which look like
brown versions of Black beauties.  Do I assume correctly, that it would be
wise to also replace those with Orangedrops?
