Cap reformation question

[J.C. Wren]

    These are big mambo-jumbo caps in a linear supply, specifically a 
nameless S-100 system.  I'm not sure if it's feasible to remove them.  
They're screwed into the motherboard, and while I could disassemble the 
motherboard from the chassis, it might still be a pain to get them out.

    Controlling the voltage into them is pretty easy, via the Variac.  
Limiting the current is a whole 'nother problem.  Maybe a light bulb in 
series with the Variac?
