Sony DXC-M3

I too am a happy M3a camper, good to know yours was an easy fix! Mine had two bad boards, but three sharp tube, Arc Tech's old one got mine working.

Personally, for the CCU-M3 I just sent 12v into the barrel socket in the battery compartment. It's center neg, so keep that in mind. Sadly my CCU has a borked pedestal pot, and it looks like some caps have gone out.
