Avantone CK7 FET Microphone - Needed Repairs

[Khron]

At this point, i'd turn off the phantom power, and operate each of the switches a good couple dozens of time each, to rule out possible contact corrosion or whatever.

Just turned off phantom power and operated switches on and off about 50 times each.

Turned phantom power back on and tried to listen through my headphones going through my Focusrite LS 56. Lots of hum and ground noise. Can't hear my voice at all now. The switches appear to be working though because I can tell the hum and ground noise are lessened when I engage the filter and pad.

Just FYI. I have some CRC Electronics Cleaner if you think I should apply it to the switches.
