(ET) Bumping up the charge voltage a tad

[CZ <cz alembic crystel com>]

Thought: Anyone know of a way to bump the charge voltage of the E20 
charger up a bit? I run the NiCDs, and I really should charge them to 45 
volts, not 42 to blow the oxygen off the plates every once in awhile.

Change the capacitor a bit? How about a boost transformer on the input 
(I could try a variac I have around). I already buck 240 to 208 on my 
car, I should be able to boost a bit. But how much?
