original failure in this one appears to be a blown electolytic

I swear, blown electrolytic caps account for about 80% of the failures I have
seen in marine electronics. Wonder what it would take to make ones that are
more reliable? I once had a Wood Freman 500 autopilot fail on a tuna voat
halfway between Midway Island and Japan.
Had to take some electrolytics from a crew man's casette deck to fix it. Given
the choice of hand steering his watches, he gladly sacrificed the caps.
