Sorry I have a kenwood m757 music system with a x45 cassett that is u/s, will a x 47 or any other fit my midi m-757 system use in the same conections please.
If it's being physical case size . . .looks like they have the identical case profile.
Feature wise, looks like the 47 offers even more tape functionality . . .
e.g. optimized CrO2 biasing compatibility
