[Boatanchors] GREAT deal on eBay!!!

[Moe Fretz]

Someone on one of these lists once said "That the only good vintage caps are
the ones that don't go clunk when you throw them into the garbage can"

Of the tens of thousands caps that I have changed over the last 15 years.
95% have had leakage excessive at anything over 50 volts.    Moe
