EMI-Netzfilterplatine
Die Netzfilterplatine behandelt die eingehende Netzversorgung, bevor sie den Transformator und die Regelstufe erreicht. Ihre Aufgabe ist es, netzgebundene Störungen zu reduzieren, die Strombereitstellung zu erhalten und einen störungsärmeren Ausgangspunkt für die übrige Versorgungskette zu schaffen.

Installationsanleitung als 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.
Prüfaufbau auf dem Messplatz
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
Ripple-Vergleich: Originalnetzteil und LPS-T8
Lower microvolt ripple means cleaner current delivery and a darker electrical noise floor.
| Vergleichspunkt | Eversolo T8 im Originalzustand | LHY Audio LPS-T8 | Ergebnis |
|---|---|---|---|
| Restwelligkeit | Factory PSU reference: 32.09µV | 3.556µV even under full 2A load | Approximately 89% lower ripple than the stock reference. |
| Rauschgrund im Ruhezustand | Stock switching architecture leaves more residual ripple. | 2.557µV static ripple at idle. | Cleaner background before playback begins. |
| Laststabilität | Higher ripple rises against the upgraded linear supply baseline. | Maintains microvolt-level noise at full 2A load. | Stable current delivery with stronger dynamic headroom. |
