Hi, Tony
Converted a Anilam 1000 awhile back, Used Gecko's, New transformer down to 80 volts, With the encoders feedback on the Table it's a little nervous, But works well. Lost a little top speed with the 100 v to 80 v though
Pixies may be hard to get now, Have used Rutex in the past, may be hard to get also, There other +- 10 volt boards out there, Hopefully others will comment on them.
Hope this Helps, Chip
