Learned the hard way that the ADC-20 drains too much juice to leave it plugged in for hours before the show (which is why my BP-50 died on me on Friday).
Got me thinking about my V2, which I never had a problem leaving plugged in (but turned off...no on/off on the ADC-20, so I *have* to unplug it). I think I know the answer, but can the V2 draw juice while the power switch is off?
