Hi Gang,
I've had a couple comments about 5x500V not being enough for 2488V and that I
should use 6 or 7 caps. When I was first building my ps, I was thinking along
the same lines, and if I had 6 or 7, I likely would have put them in just for
good measure. On the other hand I also rationalized it by thinking those
capicator designers have already put in a safety margin to meet their MTBF
stats, and I know that my p-p best case is 2488, even exceeding 2248 it
woudln't be a normal or prolonged use case, so why should I add yet another
safety margin to the system. So far, so good. I guess I could replace them
with the 8 3900uf 450V caps I got for free the other day.
73,

I've been following the filter cap thread a bit just because I guess.
For right or wrong, the PS I built last year has 5 x 500V 490uF caps that seems
to be fine for my 2488 no load 3cx800 ps. There was one reason I chose to use
those caps, I got them for free as samples along with all the rectifier diodes.
