I have seen the nice new posting of the very elusive Kyocera PL-901 and would like to make a minor correction to the description in the text: The PL-901 does have pitch controls, for each speed there is one and they can be seen in the second pictureof the TVK photos, the small cylinders behind the speed control knobs are the potentiometers for fine tuning the platter speed.
Additional remark: the PL-901 uses the same motor as can be found in theMicro Seiki SX-111 and some other top notch Micro Seiki belt driven turntables, it is a Matsushita made brushless DC motor.
The PL-901 uses a double insulation system, i.e. it is a subchassis player and the subchassis rests on a quite heavy base. The base itself is isolated from the ground by a spring suspension. In the picture you can see the heavy spring for carrying the base and behind the smaller pylone, which carries the (in this case removed) subchassis:
Not a mystery, the Kyocera was made by Micro Seiki, only the platter and the bearing were manufactured by Kyocera:
