Greetings all... I have a 1963 vintage R390A that I’m going through.
Right now, the RF section is getting attention.  But I’m wondering
whether C227, the stud mounted cap on the RF deck should be
replaced.  I usually terminate and replace all paper caps without 
prejudice in vintage electronics, but I believe this one is an oil-
filled cap and may be more reliable than the brown beauties and
their waxy cousins.
What say you?  Use it or lose it?
