Ensure that the drive belt is set to the 33 1/3 R M setting on the pulley.
Connect the turntable interconnect between the TTPSU and the turntable.
Make sure the S1 mains transformer is plugged in and connected to the 24V AC input
terminal in the back of the TTPSU. Switch the mains power on.
ush the power button on the front panel to turn the TT SU on - When the power supply
is switched on, the Rega logo will illuminate RED, This indicates that 33 rpm is selected.
To change to 45R M press the 33/45 button, this will turn the Rega logo to GREEN and
will select 45 rpm.
To select 33 1/3 R M press the button again and the Rega logo will return to RED.
PLEASE NOTE: hen using the TTPSU always leave the belt in the
top position as illustrated.

The TT SU has been designed to be easy to use, and above all to reproduce music.
There are two different versions of the TTPSU (Turntable ower Supply Unit):
TTPSU STANDARD - Used as an upgrade for 50Hz 3-24 classic, 5, and RP3 models,
supplied as standard with all RP6 turntables.
TTPSU SPECIAL - Used as an upgrade for 60Hz 3-24 classic, 5, R 3 Models.
The aesthetic design of the TTPSU was as important as the quality of its electrical
capabilities, so it benefits from the same aluminium case as the Rega Ear Headphone
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 - IMPORTANT
Only use one S1 mains transformer, NEVER connect a S1 to the turntable and to the
TTPSU simutaneously. The S1 supplied with your turntable is no longer required when
you use the TTPSU.

INTRODUCTION
The TTPSU and motor anti-vibration circuit is a combination of the long established 9
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 9 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-R M DC relay control voltage used to activate the anti-
vibration circuit.

DO'S AND DON'TS
-NEVER connect both the upgrade power supply box and the Rega S1 power supply to
the turntable at the same time - this may damage the TT SU unit.
-Do not unplug the power supply from the turntable whilst the unit is on - turn off the
power supply before unplugging.
-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.
The TT SU incorporates resettable fuses in the driver amplifier to protect it from over
current faults, which will cause the turntable to run erratically or not at all. If in the rare
circumstance these are activated, they are reset by turning off the TT SU by the front
panel for approximately 10 seconds. If the fault should persist consult your dealer.

Notes on the TTPSU special only (60hz):
When changing speed from 33 1/3 to 45 R M on the TTPSU Special upgrade supply we
suggest you observe the following:
It is advised to turn power supply & turntable on with 33 R M selected on the power
supply, and then selecting 45 R M using the speed control switch on the power supply
unit.
We suggest you avoid selecting 45 R M on the speed switch on the power supply box and
then turning the TTPSU 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 R M.
When using the RP3 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. For longer periods it is
advisable to turn the TT SU off. (see Setup - getting started section for information on
the RP3 TTPSU Special).
To switch off at any time, simply press the power switch on the front of the TTPSU.
To minimise the risk of hum pick up by the cartridge, the power supply should be situated
as far from the turntable as the interconnect cable will allow.
