Gold Note PSU-1 External Power Supply for PH-1
690,00 €
The Gold Note PSU-1 is an external inductive power supply for the Gold Note PH-1 phono stage. Dual inductive filtering, an inductive noise suppressor and low-noise ±14 V regulation help deliver cleaner power to its analog circuits. The separate enclosure also helps isolate the PH-1 from electromagnetic fields. For vinyl listeners, this can mean less background noise, clearer detail and greater dynamics.
The Gold Note PSU-1 is an external inductive power supply made specifically for the Gold Note PH-1 phono stage. It supplies cleaner power to the PH-1 circuits while placing the power supply outside the phono stage. For PH-1 owners, the result can be a quieter foundation for vinyl playback.
Dual inductive filtering removes impurities and interference from the mains supply. Low-noise ±14 V regulators then serve the analog circuits, supported by an inductive noise suppressor. Together, these elements reduce unwanted electrical disturbance before it reaches the PH-1.
The PSU-1 suits listeners seeking lower background noise and more audible detail from their records. Its external design also helps isolate the phono stage from electromagnetic fields. With less interference, vinyl reproduction can sound more precise, dynamic and natural.
Benefits
- Dual inductive filter – Filters incoming power to reduce disturbances reaching the PH-1 circuits.
- Dedicated Gold Note filtering – Addresses impurities and interference arising on the power line.
- Dual-mono construction – Uses an inductive design with two independent channels.
- Low-noise regulation – Provides ±14 V voltage regulation for the analog circuits.
- Inductive noise suppression – Works alongside the regulators to limit power-related noise.
- External enclosure – Helps shield the PH-1 audio signal from electromagnetic field effects.
- Stable output – Maintains 0.05% voltage stability across all outputs as mains voltage or load changes.
- Fast response – Reaches full power in less than 3 µs.
Who Is This For?
The PSU-1 is a separate power accessory for the Gold Note PH-1 phono stage. It is intended for listeners who already use the PH-1 to play vinyl records. The PH-1 handles the audio signal; the PSU-1 supports its operation by supplying power.
Choose it when background noise makes quiet passages or fine recording details harder to hear. Cleaner power reduces unwanted strain on PH-1 components that can disturb the signal. This can make subtle information easier to follow without changing the PH-1’s role in the system.
The Gold Note PH-1 is the compatible model named for this supply. Its dedicated application gives PH-1 owners a clearly defined upgrade path. The PSU-1’s black finish also keeps its appearance consistent with a compact stereo setup.

Why Choose the Gold Note PSU-1?
Power quality matters to the PH-1 because electrical disturbances can affect its audio signal. The PSU-1 combines line filtering, inductive noise suppression and regulation in a dedicated external unit. This arrangement gives the phono stage a cleaner electrical supply.
Its two independent channels follow a dual-mono approach within the inductive power design. Meanwhile, the external enclosure helps separate the PH-1 from electromagnetic fields. These choices target two sources of interference: noise carried by the mains and fields around the equipment.
The PSU-1 also responds quickly when full power is required. Automatic mains-voltage selection accommodates the stated 100/120 V and 220/240 V supplies at 50/60 Hz. In use, reduced background noise can reveal finer record details and a wider sense of dynamics.
