Chinese Tube Mic Power Supply Knob Removal Hack

So, I just now discovered a 10mm hex socket is a perfect fit for the nut on the power supply knob and you can easily remove the nut holding the knob with it without having to cut into it with a Dremel, or otherwise destroy the knob to get to the nut. I did this on a power supply I recently got from Chunger. Just remove the cap on the end of the knob that hides the nut and slip on the 10mm hex socket and turn. Voila.
