An interesting, somewhat rare turntable was listed on Craig's List Boston, so I went over and bought it last night. It's a Braun PS-500, which was designed by the legendary industrial designer, Dieter Rams. It has some interesting features, including a drive system not unlike that on the Thorens TD-124, but in reverse; the motor pulley drives an idler tire, which in turn drives a pulley with a belt that spins the platter. There is a tapered pulley connected to the belt that allows fine-tuning of the speed via a rotary knob. It can also play all four speeds, which is a nice bonus. It is a semi-automatic in that the arm lifts at the end of the side and the motor switches off, but it will need to be manually returned to its rest. The auto-shutoff function can be disabled via a slider switch at the base of the arm. The platter has an inverted bearing with an aluminum sub-platter and a heavy steel platter that nests on top of it. The arm and platter are de-coupled from the motor by a 3-point oil-dampened spring suspension. A very impressive design! The machine is quite heavy, about 7 or 8 lbs. The seller purchased it new in 1971, and as you can see it is in remarkably clean condition. All of the rubber parts (belt, idler, mat) are pliant and do not appear to need replacing. I haven't had a chance to spend much time working on it yet, but there are some things that will need attention. The suspension seems to be a bit out of whack, but that should be easy to adjust from the bottom. (There are adjustment screws for that.) I also noticed an oil stain inside, which is of some concern and might be related to the suspension issue. These problems aside, it runs quietly and holds a consistent platter speed. The headshell has a standard SME-type coupling, but because the arm is pretty short (8.75" IIRC), most headshells are too long to allow for proper alignment. The headshell that came with it is unfortunately compromised and may be repairable, but in the meanwhile I was able to source two NOS headshells from Thakker in Germany for about $50 each. The cartridge that was glued to the headshell is an Andante H, which I understand is an entry-level conical MM made by Sumiko. (I was able to get it separated from the headshell.) While I'm waiting for the headshells to arrive from Germany, I'll do some more poking around inside.
