Hi Can anybody tell me the Volts and Amps of the standard steppers used on Boxford 125tcl.

Retro fitting with Mach and new drives and Would like a bit more speed from it so hoping to run with higher voltage but to save me some grief with trial and error then any advise for what worked for you welcome.

Also think the Diode on the Gemini speed controller has fried because was playing with it in Manuel mode before ripping guts out when the bloody thing started going Snap crackle pop.!! . . Now the board still lights up but Not starting spindle.? Think it may be fubard but not checked it out properly yet.! Any comments or suggestions for a replacement if it's Kfukd.?

Also need a Chuck has it don't have one. No experience with these little lathes and the spindle doesn't have threads just threaded holes in the front face so any Decent close up pics of the old one and how fastens would be most welcome. Along with source of replacement.!!
