I plan on reboxing one of mine also. Originally I thought about using a 9.5 AH sealed lead battery lifted from my daughter's Power Wheel motorcycle.
.... With the batteres it is very smooth and warm.
I have ordered a 13.5 volt, 1700 ma power supply from PartsExpress...
I will report on the difference in sonics once the new PS arrives.

I would be very interested in your results. I know others have said it sounds better on batteries than when using a trafo but I honestly didn't hear a noticeable difference between eight AA batteries, a 12V motorcycle battery and this 1A wall wart.

My "new" scope should arrive today so from now on I'll actually be able to do some objective testing.
