eg &g torque systems servo card manual

hi all first post here,
i am looking for a manual for eg &g torque systems servo drive,
model no.acu3015-100d. i have two cards in an anilam crusader m cnc
mill retrofit. i bought the whole thing and it is my first attempt at
cnc. unfortunately the drive cards are bad. i would like to attempt
to repair them, but i need some info/schematics/ tuning manual for
these cards. i would be willing to pay a small fee for someone's
trouble if need be. i cant find any info on the net. any suggestions
for a possible replacement drive? 15amp, tach feed back servo motors,
100vdc bus power, +15/0/-15 control voltage., d/a i think is 5v.? any
help is greatly appreciated. ive fixed other problems with this
control and this is all i need so i can start winging chips!
