LPS-T8
Комплект модернизации линейного питания для Eversolo T8 без резки корпуса
LPS-T8 — комплект модернизации линейного питания для Eversolo T8 без переделки корпуса. It replaces the stock power path with three coordinated modules: a DC linear regulator board, an EMI AC filter board, and a shielded Sedlbauer toroidal transformer. The design focuses on lower output ripple, improved power-path stability, and cleaner current delivery for high-resolution playback.
Замена без переделки корпуса: installs without irreversible modification, helping preserve the original T8 service path.

Точная стабилизация
LT3042-based linear regulator stage with PNP current boost for ultra-low-noise regulation and stronger load handling.
Low-Loss
Идеальное выпрямление
LT4320 ideal-rectifier controller reduces voltage drop and power loss compared with conventional diode rectification.
Dual-Stage
Two-Stage EMI Filtering
RIFA X2/Y2 safety capacitors and common-mode chokes help suppress line-borne interference at the AC input.

Условия и результаты испытаний
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.
Схема стендовой проверки
The measurement setup verifies the upgraded power path under controlled input, load, and probing conditions before the ripple results are reported below.
