Introduction
The TT PSU has been designed to be effective, easy to use, and above
all to reproduce music with outstanding effectiveness.
There are two different versions of the TT PSU (power supply unit):
P7 TT PSU - this is supplied with ALL P7 turntables and for the upgrade
of the P5 50Hz.
P5 60Hz (USA) TT PSU - this is supplied for the upgrade for the P5
Turntable where the line & mains supply is 60Hz (this is not useable with
the P7).
The aesthetic design of the TT PSU was as important as the quality of its
electrical capabilities, so it benefits from the same aluminium case as the
Rega Ear Head phone amplifier and Fono pre-amplifier, giving it a design
which offers a familiar family feel and moreover brings it in line with its
illustrious bigger brothers.

Setup - Getting Started
Remove all Packaging.
IMPORTANT: when up-grading the P5 make sure the Rega PSU 1 is dis-
connected from the turntable power socket before connecting the TT
PSU.
Connect the turntable power interconnect from the TT PSU into the
turntable.
Make sure the PS1 mains transformer is plugged in and connected to the
24v AC input terminal in the back of the PSU. Switch the mains power on.
Push the power button on the back panel to turn the PSU on - When the
power supply is switched on, the front power L.E.D. switch will light up
red. This also indicates that 33 rpm is selected. To deactivate 33 rpm
press the button inward's, this will turn the L.E.D. to green and will have
selected 45 rpm.

To deactivate 45 rpm press the button again and the L.E.D will return to
red, re-selecting 33 rpm, (NOTE: When changing between speeds,
please do not adjust the belt drive from 33rpm on your P5!)
When changing speed from 33 to 45 RPM on the P5 60Hz up grade sup-
ply we suggest you observe the following:
It is advised to turn power supply & turntable on with 33 RPM selected on
the power supply, and then selecting 45 RPM using the speed control
switch on the power supply unit.
We suggest you avoid selecting 45 RPM on the speed switch on the
power supply box and then turning the TT PSU or turntable power switch
on, this could under some circumstances cause the motor to stall and the
turntable may not reach the correct operating speed of 45 RPM.
When using the P5 it is still possible to turn the turntable off using the
switch on the turntable, this is perfectly ok for short periods of non use,
but for longer periods of non use it is advisable to turn the TT PSU off as
well (see Setup - getting started section for information on the P5 60Hz
(USA) TT PSU)

To switch off at any time, simply press the power switch on the back of the
TT PSU.
To minimise the risk of hum pick up by the cartridge, the power supply
should be situated as far from the P5/7 as the interconnect cable will
allow.

Do's and Don'ts
Do not unplug the power supply from the turntable whilst the unit is on -
turn off the power supply before unplugging anything.
Do not operate the power supply without the turntable connected.
As you would expect there is a 24V AC plus a 20V DC signal present on
the pins of the plug - if these are shorted it will cause damage to the power
unit.
Do not connect both the P5/7 up-grade power supply box and the Rega
PSU1 power supply to the turntable - this will damage the P5 PSU unit.

Specifications
The all new TT PSU and motor anti-vibration circuit is a combination of the
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 therefore keeping the sources of hum &
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 stabilised DC
power supply, generates a 24Volt AC balanced signal of less than 0.05%
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 33/45-RPM DC relay control voltage used to
activate the anti-vibration circuit.
