While it may do some good to reform oil capacitors,

any solid information indicating that a slow ramp-up on more-or-less
modern electrolytics does much good?
I've wondered this myself. I've also wondered what a suitable
definition of modern is. I've had capacitors explode on sudden power
application. I've never had one explode on a slow ramp with a variac,
but I've had them warm up. I've also seen DC current decrease over
the course of several hours when applying low DC voltages to boards,
but I've never been able to confirm the same with a variac.
I'm more of the "duck and plug" mindset
myself.
Again, with a CRT in the mix, I worry about the damage an exploding
capacitor can do.
