I just got a Tubefex from a friend of mine. It only works in mono mode (only one output is working). He said he remembers making it only work in mono, as that's the only way he plays...but...it's been quite a while since he used it and he can't remember how he set it up...and he's lost the owner's manual. Has anyone heard of a global setting to make things run in mono, only? Would reinitializing the unit bring it back into standard stereo mode? I'd appreciate any thoughts or information anyone might have.

Thanks!
