50 A 1000 Volt rated should work then.

I can mount an old computer heat sink to the top of the case.
Now if I can find a couple of panel voltmeters and a DC ammeter, I
should have a linear rectifier as good as the one in the $8000 kit.

It just seemed easier to buy a rectifier than to build one. But to
get 25 amp, I may need to build.
Get a pre-packaged bridge rectifier. They usually are square, have four
terminals, and have a metal pad with a hole through it for bolting to a
heat sink.
You should get a bridge with at least a 400 V rating (the capacitor will
store 120*sqrt(2) DC and the reversed diode will see the line go opposite
polarity, for a total of 2*120*sqrt(2) ).
Buy, don't build. If you'd like I can search for a source of the right
kind of thing tomorrow.
