It's entertaining though ! Talking of 'scopes, finally found 5 minutes today
to get the covers off my 100 meg Hitachi that went wrong last week. You know
nothing's built to last these days - it's only been 20 years since I
"borrowed" it off the last company I workd for, and it's not as if it's on
any more than 350 days a year, or 16 hours a day ... Anyways, my trusty Bob
Parker ESR meter quickly pointed me at a 2200uF cap on the -12v rail.
Completely open. It's amazing at how far electrolytics have come on. The
replacement was about half the size or less than the original, and was a
better temp rated 105 deg over the original 85 deg.
