Re: [CAD_CAM_EDM_DRO] electrical help wanted

Besides the recommended 100V, use about 3000 - 4000uF per 1A of current.
Cap value too low, and ripple will be high
Cap value too high, and you could pop the diodes through stress

Since the Gecko amps are fairly tolerant of ripple, you should be ok. No
need to bother with low ESD caps if you are using 50Hz /60Hz
