Dear model admins,

this model is identical to the MP-400, if you take into account that the tube lineup here is wrong (a two step audio amplifier with an additional detector tube?). Fully correct specs on the Multi-Panel-400 are given on the DeForest Radio Equipment catalogue page posted with the MP-400 linked above. Please move model.
