Jeff,
With the combination you have of the 260's and the 42 series motors
you will need all the power you can get.
The 260's are rated for 80 volt at 8 amp and it would be adviseable
to get somewhere near these limits.
With a 50 volt AC supply, by the time it's rectified and smoothed,
you will have 70 volts DC which is close enought to 80 volts but not
too close to cause over voltage problems.
