Fixing a $10,000 Datron Calibrator - Datron 4700 Repair Part 4 - No.830

I finish the repair of my Datron 4700 calibrator. The Datron 4700 is very similar to the Datron 4705, Datron 4708, as well as the Datron 4200A and Datron 4000. I find a couple more problems which the cause of the high voltage output fault and fix them, and then test the resistance and current functions to confirm that they are working correctly.
