Just disassembled my entire 7700 final, and somebody immediately took all the space.
I must say, the sound is much more natural now, albeit the only sounds I heard are "miow" and "prrr".



I was surprised at the excellent build- all Sanyo transistors used and professional module boards, furthermore, even the cabinet metal is very thick and stiff, and the front panel is very heavy indeed!

So here I am, on my quest for using the unit on 230V.
Will keep you posted!
