IMO, there no reason to make a smaller invective. The 6505mh sounds good, but not great. In AB against the real 6505 it doesnt have the punch and aggression. I wonder if the 60W switch is just disabling two tubes like pulling them physically would? If its some kind of attenuation separate from disabling tubes, it might be possible to remove two tubes and have the amp at 30W? Its fun to speculate.
