Mastech MS7221 Volt/mA Calibrator Repair - Follow Up

In my original video I had repaired a Mastech M7221 Volt/mA Calibrator by way of adding a cockroach DIL IC in place of a SMD package which I didn't have to hand. In this short video I finally get back to the Mastech and finish the job off properly.
