I've been looking at a Servomet SDM for a local hobbyist metalworker; he re cently acquired it, after it had sat for 20+ years. I managed to fix the first problem and managed to get it powered up, but after cycling the power a few times, it started blowing fuses. I'm struggling to track the fault dow n, so I need a schematic; the Servomet schematic reference number is D70701 0. Hoping someone can help. Thanks, Martin.
