KWS-1 Power Supply Restore Completed

This is the High Voltage side of the power supply. I have the low and high voltage schematics together, and will go over every change I made and make sure I did it correctly. Then I will turn it on and give it the old “smoke test”. I also need to make sure I have whatever accessory connections – antenna to TR switch, speaker muting, key and mic.

Speaking of microphones, I gave the Astatic D-104 and Shure 51 “Sonodyne” a good cleaning. Both elements inside look fine – so I will test with a guitar amplifier I have in a closet, and order a couple more of the special 2 pin mic connectors – like the one I bought a while back.
