[Milsurplus] PRC-74 Power Supply

[John Watkins]

Hi All,  

As I go through my list of gear to check out, I found
that while visually inspecting the above, I found that
C2 and C3 (tantulum capacitors) had extreme corriosion
on the negative leads.  The still tested OK, but i
have replaced them.  This is similar to what is found
in the R-390A audio module. I think that the early
tantulum caps were prone to this after time had
passed.  Anyway, please check those power supplys out
there.  caps were GE 6-66 date codes.  Will let you
know if I find anything else that might effect all of
the PRC-74s.

Cheers,
