Welcome to TalkBass George
I wouldn't get my hopes up for finding a schematic for anything made in the far east, not easily anyway.
I had to trace mine when I wanted one for my Fame BVH300.
Shortly after that, Eden published the schematics for E300T, which is nearly identical.
What do You need the schematic for?
I've only had a quick glimpse onto the guts of these, but they seemed very simple.
Almost tube amp simple
