Yeah.  I originally had the M (miniature) series caps in there,
limited to 470uF each, then I discovered these, which are 820uF each
for the same footprint.  The whole power supply uses only a 1/2"
stripe on the board.

Those are Panasonic EEU-FC1J821L caps.

The openings for the 0.5mm pitch connecter were only 6mil already; my
laser printer can't reliably print any smaller than that.  The thing
is, the brass is 5mil *thick* so by the time you etch all the way
through, the etchant has had plenty of time to undercut the toner and
do all sorts of weird things.
