INTRODUCTION
This manual outlines the maintenance procedures for using the
MELDAS AC servo system. It details the methods involved in
replacing the transistor amplifiers as well as the inspection
locations and adjustments, and it should thus be read before
operating the AC servo system. Refer to the checkpoints before
switching on the power.
