Ultra-Stable Power Supply and Motor Circuit

The Rega TT PSU and motor anti-vibration circuit is a combination of Rega's innovative P9 power supply along with an improved P25 anti-vibration motor drive feeding the P9 24V AC synchronous motor.

The TT PSU uses a remote "wall wart" transformer, which keeps the sources of hum and noise well away from sensitive parts such as the cartridge and phono leads.

The compact TT PSU 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 stabilized DC power supply, generates a 24-Volt AC balanced signal of less than 0.05% distortion, which is completely unaffected by any changes in the mains / line voltage and conditions. This drives the turntable's 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 / 45-RPM DC relay control voltage used to activate the anti-vibration circuit.

Important: The TT PSU can only be used with the P3/24 and P5 turntables. It is not compatible with any other Rega or manufacturers turntables.
