[Milsurplus] BC-611 power

[Bob Camp]

Hi

I agree that a "simple" high voltage converter makes the most sense.  
One issue would be that there's a big difference in the design if it  
runs off of 1.2 volts than if it runs off of 12. The higher the input  
voltage the easier it's going to be to make the output voltage ....
