[QUOTE="PhaseTech, post: 430608, member: 3149"] I would definitely recommend a higher voltage battery and run it through a regulator to give you a constant 7.2V. The SD's input was not regulated so every time you get a rapid drop in voltage you will hear it, just like a false signal. The higher voltage also seems to give the audio circuit a bit more boogie. Remember the SD's are pretty much not serviceable these days (depending on fault) so I would not be gambling with higher voltages. Better to be safe than sorry. [/QUOTE]
