Reed Muse 3C turntable

lewm,  Thank you for the tip on the electrolytics; I will try that and report back.  
I always disconnect the charger when listening to music because it injects noise that is clearly audible.

lewm,
The two 12v batteries are connected in series and the 24v output connects to my voltage regulator with a pair of banana plugs.  
Would connecting a single 35v capacitor at the input of the voltage regulator have the same effect as what you suggested above?

You could try it both ways, but I would start with placing the bypass capacitance after the batteries and before the voltage regulator, if for no other reason than the fact that the relatively huge capacitance can play havoc with the output of a VR.

Okay; I've ordered two of them and will try it both ways.
Thanks again.

$20k and it comes with a crap wall wart? And a user here buys a battery and charger for $100 and improves it from unlistenable to useable. I don’t get it. Poor design and marketing to release it like that.
