INTRODUCTION

The TTPSU and motor anti-vibration circuit is a combination of the long established P9

power supply along with an improved RP6 anti-vibration motor drive feeding a 24V AC

synchronous motor. The TTPSU uses a remote "wall wart" transformer therefore

keeping the sources of hum & noise well away from sensitive parts such as the cartridge

and phono leads.

The compact TTPSU uses exactly the same high stability crystal locked low distortion

sine wave generator as is used in the heart of the P9 power supply. This, along with an

efficient drive amplifier fed from a stabilised DC power supply, generates a 24V AC

balanced signal of less than 0.1% distortion, which is completely un-affected by any

changes in the mains/line voltage and conditions. This then drives the turntables anti-

vibration circuit, which is situated beneath the turntable.

The drive voltage for the motor is run along the power lead to the turntable motor, which

also carries the 33

1/3

/45-RPM DC relay control voltage used to activate the anti-

vibration circuit.
