LPS-T8
Nearly 90% Lower Output Ripple
A Complete Power Chain Rebuild
The upgrade is organized into three product sections.
DC Linear Power Regulator Board
This board handles the upgraded DC supply stage, converting the transformer output into a quieter, lower-impedance feed for the T8 audio circuitry. The materials below identify the key parts, while the table shows how they improve on the stock design.

EMI AC Filter Board
The AC filter board treats the incoming mains before it reaches the transformer and regulator stage. Its role is to reduce line-borne interference, preserve current delivery, and create a cleaner starting point for the rest of the power chain.

Installation Guide PDF
Download the official guide before installation and follow the screw sequence, wiring map, and final safety checks step by step.
Measured Under Controlled Bench Conditions
Ripple noise performance is verified with a dedicated bench setup and then reported under idle and full 2A load conditions, so the upgrade can be evaluated by measured electrical behavior as well as listening impressions.
Bench Verification Setup
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
Factory PSU vs LPS-T8 Ripple Noise
Lower microvolt ripple means cleaner current delivery and a darker electrical noise floor.
| Comparison Point | Stock Eversolo T8 | LHY Audio LPS-T8 | Result |
|---|---|---|---|
| Ripple Noise | Factory PSU reference: 32.09µV | 3.556µV even under full 2A load | Approximately 89% lower ripple than the stock reference. |
| Idle Floor | Stock switching architecture leaves more residual ripple. | 2.557µV static ripple at idle. | Cleaner background before playback begins. |
| Load Stability | Higher ripple rises against the upgraded linear supply baseline. | Maintains microvolt-level noise at full 2A load. | Stable current delivery with stronger dynamic headroom. |
