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.
More Pre-tube Options
The feature of this machine is that there are 4 tube switches inside, which are used to select different pre-tubes: WE408A/WE403A, B/EF91, 92/CV131, 138/5654/EF95/6J1 and other tubes can be used directly through the switch, bringing more fun in changing tubes.
