Okay, so I lowered the specs a bit, here's what I'm thinking of
putting in my power supply:

Transformer, toroidal, 500VA, 0-230V pri, 50/60Hz, 2x0-35V sec

Diode, Bridge Rectifier, SMT, GBPC2502

Capacitor, electrolytic, aluminium, screw terminal, 105degC, 63V,
33000uF

I'll connect the two secondaries of the transformer together in
parallel to give me the full amps. After rectification, this should
be just slightly under the target 50V. So, with 500VA, will this be
enough to run three of Dan's big,big servo motors then?

And the cap, is 63V, 33000uf gonna be enough, or will it all end in
tears, with me picking pieces of aluminum electrolytic out of my
shins?

Should I use fuses on the output, or input only, and what values
would be appropriate? Slow/fast blow? Will it make a difference, can
it save my geckos from cooking if the motor windings goes to ground?
