The Hybrid Structure of "front tube and back stone

LD1+ adopts the so-called "front and back stone" hybrid structure in the circuit design: the front tube uses 6J1 dual vacuum tubes (WE408A/EF92 available too) and the back stone uses a buffer amplifier circuit composed of op amp + discrete components mainly composed of transistors. The sweetness of the machine also has the speed of the stone machine.

High-Value Aluminum Alloy Chassis Structure

Little Dot LD1+ uses an aluminum alloy chassis structure with fine craftsmanship: the chassis adopts a secondary oxidation process with good smoothness and feel, and the electron tube is equipped with an aluminum alloy decorative ring.
