platter in strobelight

This is a close-up photo of the SL-1210 MK2's rotating platter. The red dots shown on the platter of the turntable is an indication that the rotation speed of the platter is in synched with the chosen RPM which is 33-1/3 RPM for a long playing album. If you will adjust the Pitch Control, the red dots will either appear streaming forward if the pitch control is pushed to a faster speed or will appear streaming backwards if pulled to a slower speed. The red dots will either shift upwards or downwards depending on the chosen RPM bias setting. A clever Japanese innovation which is not thought of by the Americans in their direct drive turntables. and that’s why the Technics SL-1200 MK2 and its later siblings were all-time favorites!
