It's funny, I'm always hearing about this problem but somehow I have yet to
ever run across a single one in which the lytic checked bad (ESR meter) or
blew, I know it's coming but so far never had that happen.

I have found _some_ good electrolytics in the lamps,maybe 10 percent of
them.
I measure ESR (some caps measure about right cap. value, but has high
ESR (20 ohms at 50kHz)
