Hi LatigoAmigo, thank you once again. The 335 is exactly the same bloc as my 145 only canon, I have no light on either and there are no electronically operated systems but I have a feeling the quick rotan on the side and the box on the back operate the needle set position and possibly the needle cut which I am used to operating without one, The 3 phase is a pain even for me and the weight of the motor is restrictive, plus its 3.8KW, Im not sure what I will ever need to sew with that. I like basic mechanical systems which are predictable and straight forward. I have enough computer systems around to know I dont need any more. I will order a new servo and rip the lot off. Thanks for all your help, I will let you know how I go on.
