Since I don't know what the slight differences between the two manuals are, I don't know what I want to know! I just want to have the owners manual for the amp, and have the extra or different information that is in the MK.II manual. But I'm confused---yesterday you said there was only one version of the manual, that it came with both the original and MK.II versions of the amp. Now you say there are slight differences. Are you talking about the two different manuals, or the amps themselves?
