Kenwood KD-600 Turntable Motor & Bearing Service

Given the great interest in turntables now, especially quality decks like the Kenwood KD-600/650, I thought I would share some images I took whilst servicing the motor and bearing of my own KD-600.

The Kenwood KD-600 / 650 is a classic direct drive turntable from the late ’70s. The KD-600 is a superb deck technically, for a number of technical reasons: 20 pole, 30 slot brushless motor, synthetic concrete-composite chassis, 3 kg platter, massive main bearing assembly and so on.… Read more

Sony PS-1150 Belt-Drive Turntable Service
