Special Features

'DIRECT CONTROL' drive system, combining the advantages of belt and direct drive. The belt drive is controlled by a tachogenerator in the drive pulley. This ensures a constant speed even when the load on the drive varies, e.g. due to cleaning brushes, temperature or mains fluctuations.
Tonearm balance integrated in the locking position socket.
Adjustable tracking force and antiskating. Separate scales for spherical and elliptical needle grind available for antiskating.
Sprung sub-chassis with three leaf springs coupled to the frame.
Photoelectric limit stop

Identical in construction to Philips AF 887
The stock headshell has a 1/2" hole spacing but no slotted holes, so only Philips Super M II series cartridges fit accurately. In order to be able to use pickups from other manufacturers, Philips made a 1/2" universal headshell with slotted holes with the order number 4822 402 60627.
