[R-390] The adventure begins (and a capacitor question).

These are great ideas.  I'll have to get some of that DeOxit stuff.  But I'm
a big fan of pre-emptively changing capacitors.  I guess this comes from
getting what was my grandfather's Stromberg Carlson Model 60 working.  This
radio was from the 1930's and the capacitors were pretty ugly.  There was
waxy oily stuff dripping off of many of them and some were encased in tar.
So I was pretty ruthless.  I replaced every single paper, oil, or
electrolytic capacitor with polyester or a new electrolytic and now it works
great.  Maybe that's overkill, but I won't have to worry about those
capacitors for a long time.
