Sorry it this is in the wrong forum. I have a Wasino LJ-103m lathe which was manufactured in 1986. The Fanuc Servo board for the C axis (A20B-1000-0560) is dying on me. I have found a local dealer that will sell me 2 of these boards at a substantially discounted price then if I just purchased 1. My question is, what is the normal lifespan of these boards? Should I expect the other ones to start failing as well? Or is this an impossible question to answer. Thanks.
