Im mounting some rather large 80V steppers on my lathe. Im having a hellava time finding any way to power the thing. Where do you guys normally find these huge DC power supplies?
Er, cheaply, if possible.
Thanks in advance!

Not sure if these have enough current for you, but I bought my 60v PS from these folks:Antek - Your reliable source of transformers, power supplies, and more.

I build my own using antek transformers. Gecko has a good white paper on unregulated power supply design, they are not hard to make.
I used a toroidal transformer, bridge rectifier bought locally and capacitors out of an old high end audio amp.
Built my first one by rewinding a microwave transformer years ago and it's still working great, but the toroid is definitely a better option.

I like automation technologies inc they have a regulated 5v supply out, and I think they have wires to add 12 or 24 to (not exactly sure if they all have that)
I bought a surplus 420va toroid for $10 and added extra windings to provide the voltage I need.
