The successor to the D3, and a very unusual beast. First, the platter is recessed into the base to create a lower profile than the D3. Closer to the later P-mount straight arm machines to come. Second, the integral rotor-platter design was kept, but the coils were actually printed on a circuit board, with the rotor magnet suspended above the printed coils. Still effective, but a bit less torque than the D3. Third, the Memo-Repeat was gone, replaced with a standard Repeat switch. Fourth, the record size was selected by the push-pin detection system (shared with other models around the same period, like the Q303). That was actually a good thing if the machine is properly maintained. Fortunately the quality of the construction and especially the arm were kept up. Nice general-purpose turntable. Not the flashiest, but it won't embarrass if given a good cartridge. And readily available for reasonable prices unlike other Technics models. Would get a 10/10, but there's that blasted dust cover hinge thing again.
