The New LPS-T8
Linear Power Upgrade Kit for Eversolo T8
From AC input to regulated DC output, give the T8 a more robust internal linear supply path.
A low-ripple, low-impedance internal supply path for Eversolo T8
LPS-T8 follows the real power path inside the player: the EMI AC filter board first treats line-borne interference, the LHY AUDIO hand-wound shielded toroidal transformer provides isolation, LT4320 rectification with Nichicon reservoir filtering and LT3042 linear regulation forms the DC stage, and OCC copper internal wiring completes the connection into the T8. It does not change the T8 digital platform; it focuses on supply noise, path impedance, and an internal installation that fits the chassis without cutting.
Why Upgrade To LPS-T8?
The T8 already uses a linear power architecture. LPS-T8 is for owners who want to take that foundation further: a production power design must balance cost, space, heat, reliability, and consistency, while LHY AUDIO focuses this upgrade specifically on power-supply engineering.
Common Owner Feedback
These are subjective listening notes from upgraded systems; the exact result will vary with system matching, cables, music, placement, and room conditions.
From AC Input To Regulated DC Output
For buyers who want to verify the engineering, each stage is detailed with component choices, factory reference points, and the intended electrical benefit.
Dedicated EMI board with RIFA X2 / Y2 safety capacitors and large OFC-wound common-mode chokes.
LHY AUDIO hand-wound toroid with OFC copper, copper shielding, and controlled vibration damping.
LT4320 rectification, Nichicon filtering, and LT3042 regulation for lower-impedance DC delivery.
Single-crystal OCC copper harness completes the internal connection path after the regulated DC stage.
Controlled bench data shows ~90% lower measured ripple versus the stock PSU reference.
EMI AC Filter Board
The EMI board treats the incoming mains before it enters the transformer and regulation stage. Its role is to reduce line-borne interference, preserve current delivery, and give the rest of the power chain a cleaner starting point.
