1. Introduction
The GOLD NOTE PSU-5 is an external inductive power supply specifically designed to enhance the performance of the Gold Note PH-5 phono stage. It provides ultra-clean power to optimize audio signal integrity and improve the overall vinyl reproduction experience.
Inspired by the design philosophy of other Gold Note external power supplies like the PSU-10 and PSU-1000, the PSU-5 features a linear power supply with custom-made transformers and an inductive filter to effectively prevent noise and interference from the AC power grid.

3. Setup
Follow these steps to properly set up your GOLD NOTE PSU-5 Inductive Power Supply:
- Placement: Place the PSU-5 on a stable, level surface, away from direct sunlight, heat sources, and excessive moisture. Ensure adequate ventilation around the unit. Avoid placing it directly on top of or underneath other audio components to minimize potential interference.
- Power Off: Before making any connections, ensure that both the PSU-5 and your Gold Note PH-5 phono stage are powered off and disconnected from the AC mains.
- Connect to PH-5: Connect one end of the supplied connection cable to the dedicated power input port on the rear of your Gold Note PH-5 phono stage. Connect the other end of this cable to the corresponding output port on the rear of the PSU-5. Ensure a firm and secure connection.
- Connect to AC Mains: Connect the supplied power cable to the AC inlet on the rear of the PSU-5. Then, plug the other end of the power cable into a suitable AC wall outlet. It is recommended to use a high-quality surge protector or power conditioner.
- Power On Sequence: First, power on the PSU-5 using its power switch. Wait a few moments for the unit to stabilize. Then, power on your Gold Note PH-5 phono stage.
Important: Always ensure all connections are secure before powering on the units. Incorrect connections can lead to damage or improper operation.
4. Operation
The GOLD NOTE PSU-5 is designed for straightforward operation, primarily serving as a dedicated power source for the PH-5 phono stage.
- Power Indicator: A small LED indicator on the front panel of the PSU-5 illuminates when the unit is powered on and operating correctly.
- Automatic Operation: Once connected and powered on, the PSU-5 automatically provides the optimized, ultra-clean power to the PH-5 phono stage. There are no user-adjustable settings on the PSU-5 itself.
- Power Off Sequence: To power down your system, first power off the PH-5 phono stage, then power off the PSU-5. This sequence helps prevent any potential transient noises or stresses on the components.
For detailed operation of your PH-5 phono stage, please refer to its dedicated user manual.
5. Maintenance
To ensure the longevity and optimal performance of your GOLD NOTE PSU-5, follow these simple maintenance guidelines:
- Cleaning: Disconnect the unit from the power outlet before cleaning. Use a soft, dry, lint-free cloth to wipe the exterior surfaces. Do not use abrasive cleaners, waxes, or solvents, as these can damage the finish.
- Ventilation: Ensure that the ventilation openings are not blocked. Do not place the unit in an enclosed cabinet without proper airflow.
- Environmental Conditions: Avoid exposing the unit to extreme temperatures, high humidity, or dusty environments.
- Cable Connections: Periodically check all cable connections to ensure they are secure. Loose connections can degrade performance.
The PSU-5 contains no user-serviceable parts. Do not attempt to open the chassis, as this will void the warranty and may expose you to dangerous voltages.
