I just picked up a used Radio Shack 15-1254 Rotator only..no control box or specs... Does anyone know what the drive voltage requirements is on these 1

I use them in my $65 tracking system. See the schematic on my web page: http://www.ew.usna.edu/~bruninga/rotator1.html

Its about 24-30 VAC with a capacitor to provide phase shift to give the correct direction.
