Audio T Verdict
The Rega PS1 is the genuine replacement power supply for compatible Rega turntables, phono stages and turntable power supplies requiring a 24 V AC, 350 mA adaptor.
It is ideal when the original PS1 has been lost or damaged, or when a genuine spare is required. This is a like-for-like replacement rather than a performance upgrade.
Compatibility must be confirmed before ordering. A generic 24 V adaptor should not be substituted, as many alternatives produce DC rather than the 24 V AC required by compatible Rega equipment.
Rega PS1 Replacement Power Supply
The Rega PS1 is a genuine UK replacement mains adaptor providing a 24 V AC output at up to 350 mA.
It is used with a range of compatible Rega products, including selected turntables, external phono stages and the Neo MK2 turntable power supply.
The PS1 is intended to replace the original Rega adaptor supplied with the product. It does not alter the motor circuit, add electronic speed control or upgrade the audio circuitry of the connected component.
Compatible Rega Products
This PS1 is suitable for Rega equipment that specifically identifies the Rega PS1 or a 24 V AC, 350 mA Rega supply as the required power source.

Check Compatibility Before Ordering
Do not choose a replacement supply from the voltage figure alone. The connected product must require a Rega PS1 with a 24 V AC output and the correct connector.
Some Rega products use different external power supplies even where their voltage appears similar.
Contact your local Audio T store
with the product name, approximate age and a photograph of the power input or original adaptor if you need help confirming compatibility.
24 V AC Output
The PS1 produces alternating current at 24 V AC, with a maximum available output current of 350 mA.
This is different from the 24 V DC output produced by many generic power adaptors.
The fact that another supply is labelled 24 V does not make it compatible. Using an incorrect AC or DC adaptor, unsuitable connector or wrong mains version could prevent operation or damage the connected product.
Do Not Substitute a Generic 24 V DC Supply
The Rega PS1 output is 24 V AC. It should not be replaced with a conventional 24 V DC adaptor.
Use the genuine PS1 or another replacement specifically approved by Rega for the connected product.
A Replacement, Not an Upgrade
Replacing a correctly functioning PS1 with another PS1 should restore the same intended power arrangement rather than change the performance of the product.
It is suitable when:
- The original Rega power supply has been lost
- The original adaptor or cable has been damaged
- A genuine spare is required
- A technician has confirmed that the existing supply is faulty
- The correct UK-market supply is required for compatible equipment
If the connected product remains inoperative with the correct replacement PS1, the turntable, phono stage or power supply may require inspection.
Connecting the Rega PS1
- Switch off the connected Rega product.
- Disconnect the original power supply from the mains.
- Confirm that the product requires a 24 V AC Rega PS1.
- Connect the PS1 low-voltage plug securely to the product's power input.
- Plug the PS1 into a suitable UK mains socket.
- Switch on the mains supply and then operate the connected product normally.
Do not pull the adaptor from the socket by its cable and do not place strain on the low-voltage connection.
Positioning and Reducing Hum
Power adaptors can generate electromagnetic fields which may be detected by a turntable cartridge or sensitive phono-stage circuitry.
Position the PS1 as far from the cartridge, tonearm cable and phono stage as the supplied lead reasonably allows.
Avoid placing it directly underneath the turntable, on top of a phono stage or beside loosely coiled turntable signal cables.
Where mains and audio cables must cross, arranging them approximately at right angles can help reduce induced hum.
Safety and Care
Use the power supply indoors in a dry and well-ventilated location.
- Do not expose the PS1 to rain, moisture or spilled liquids
- Do not cover the adaptor while it is operating
- Keep it away from radiators and other heat sources
- Do not use it if the case, mains pins or cable are damaged
- Do not open the casing
- There are no user-serviceable parts inside
- Disconnect it from the mains during extended periods of non-use
If the adaptor becomes unusually hot, operates intermittently or produces smoke or an unusual smell, disconnect it from the mains and contact Audio T.

Frequently Asked Questions
What is the Rega PS1?
It is a genuine external mains power supply for compatible Rega turntables, phono stages and turntable power supplies.
Is the output AC or DC?
The PS1 output is 24 V AC at up to 350 mA. It is not a 24 V DC adaptor.
Can I use a generic 24 V power supply instead?
Not unless Rega has specifically approved it. Many generic 24 V supplies produce DC and may also use an unsuitable connector.
Does it work with the Rega Planar 1?
Yes, where the turntable requires the Rega PS1 24 V AC supply. Check the original adaptor or product documentation if the model or age is uncertain.
Does it work with the Rega Planar 1 Plus?
Yes. Rega specifies a PS1 24 V AC, 350 mA supply for the Planar 1 Plus.
Does it work with the Rega Planar 2?
Yes, where the turntable was originally supplied with the matching Rega PS1.
Can it power the Rega Neo MK2?
Yes. Rega specifies the PS1 as the wall-plug power supply for the Neo MK2.
Can it power the Fono MM Mk5 or Fono MC Mk4?
Yes. Both models are designed for use with the Rega PS1, although their internal current requirements are lower than the supply's maximum 350 mA capacity.
Will a new PS1 improve sound quality?
It is a like-for-like replacement rather than a performance upgrade. It should restore the intended operation when replacing a missing or faulty original supply.
Why should the PS1 be kept away from the turntable?
The electromagnetic field produced by a mains adaptor may be picked up by a cartridge, tonearm cable or sensitive phono stage and heard as hum.
What should I do if the product still does not work?
Disconnect the equipment and check that the correct PS1 has been supplied. If the problem remains, the connected Rega product may require inspection.
Can Audio T confirm compatibility?
Yes.
