I'll try this again since my reply seems to not have posted...

I planned on sacraficing the Opto to protect the board as much as
possible, when I'm ready. I just got the drives mounted to the
heatsink tonight and found a couple of used xfmrs that should give me
72vdc output (34vct each using 1.5 windings for 51vac :).

Never tried the Pin Vice and Drill Bit route, I'll keep it in mind.

Thanks
mike
