[R-390] Post to list

[Jack Sullivan]

On R-390 (not "A" version), I am about to replace most
all paper condensors (we now call them capacitors, of
course), probably with polyprop. orange drops.  I see
that these types of  condensors in this set are metal
covered, and look to be of very high quality (military
spec., I am sure, is reason for that).  Are these
metal covered, numerous ones are .01, .1, .22, 1. mf,
really paper caps, as I suspect?  I have replaced a
gazillion paper caps in civilian radios, but have no
experience with military radios/electronics, and have
never seen metal covered ones like this before. 
Anyone know much about the quality of these metal
covered condensors, how smart it is to replace them,
etc.?  I will replace, too, any electrolytics that I
find not testing well (the 50 mf., 50 volt unit will
be first to replace, as it is shot, for sure, as
tested), while two 10 mf are in great shape, and I
will leave them in place.  Best,  Jack
