It just occurred to me that the everything I needed should have been in the APC 650 UPSs I recently pitched. Including the heat sink. too bad I can't modify one of them to work.

The hoarders lament: As soon as I DO pitch something, I soon will need it. Some corollary to Murphy in there... If you keep it you won't need it, if you pitch it, you will soon have a need for it.

 50 A 1000 Volt rated should work then.

Yes, that is what I was describing.


 I can mount an old computer heat sink to the top of the case.

It will have to be a fairly big heatsink (or else have a fan for forced
air cooling). You want something that has a thermal resistance of
1 deg.C./Watt or less.


 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.

Only yours won't be regulated. If your line voltage changes, your DC out
will change, too.
