I constructed a bridge using 20 of the 1200V Cree Schottky diodes and used .01uF 1250V caps to equalize the voltage instead of resistors (see picture). It's been running for 7 months now rectifying the 2500VAC supply in my Midlife Crisis 833C amps with zero issues, and the caps also serve to snub kickbacks from the choke-input supply. B+ is ~2300VDC.
I was trying to keep the bridge compact and minimize heat generation, and it seems to have worked well. Since the picture was taken (and before use) I removed the unused solder pads on the perf boards near the high voltage areas and gave the connections a coat of corona dope to help prevent arc-overs.
