i've got a Sony magnescale on my lathe, and it looks like the scale(or cable or adapter, but i think it's the scale itself) is bad. when i move the cross slide inward it reads positive. when i move the cross slide outward, it gets choppy, but continues to increment to the positive! i've swapped the inputs from the apron scale and it, and the problem follows the crossslide scale. i've googled a bunch, but i don't find any comprehensive websites on the topic aside from the sony instruments site, but they don't talk about repair or how to order a replacement.
the magnescale is a model LF-200, and the scale is a SR-745 10/250. it's
14.5" overall length and looks like it has about a 12" read lengthwho have you worked with that's knowledgable, reputable, and will take a phone call?
thanks,
