On these gearboxes the reduction ratio is the number before the KA on
the gearbox. 7.5KA = 7.5:1 reduction. And yes the PH266 series is
rated at 83ozin. The -01's are 6v @ 1.2A, but i cant find my spec
sheet with the torque profile at this time, thats what I get for
cleaning up. ;)

On the winding connections for 6 wire...
A - Black
Center Tap - Yellow
(NOT)A - Green
B - Red
CT - White
(NOT)B - Blue
