I've only been using a variac for a short while to bring a chassis up slow. So far, I haven't noticed any improvements on lytics, but, it has helped me locate a few that were evidently shorted. I would get the juice up to about 40 or 50 volts, and usually find at least one lytic to be pretty hot. I would then change the hot one before taking it any further. Probably saved me from having a nasty surprise. Before having a variac, I was usually always leery of plugging in a set for the first time.
