[R-390] Post to list

[Llgpt at aol.com]

On a R-390/URR. there isn't a capacitor problem as there is in the cost  
reduced R-390A/URR. (See how simple that is for the "NON A ")  challenged???????
 
Unless you have aprticular problem with capacitors "actually" leaking on a  
R-390/URR, leave them alone.
 
YMMV and may the force be with you.

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
