This is basically a model 310 turned sideways with it’s rotor removed. It’s service manual is combined with the 310 and the speaker and amplfier components are shared with that model.
This cabinet has NO rotational effects what so ever, and is simply a self powered PA cabinet with instrument level input, volume, treble, and bass controls.
This cabinet was built by Nihon Hammond, a Japanese division of the “Old” Hammond company (not to be confused with Hammond Suzuki), very few if any were sold in the USA.
