Little Dot LD1+ 6J1 Hybrid Headphone Amplifier Front Tube Back Transistor Amplifier 10Hz-50KHz
Description:
1. In the circuit design, the so-called "front tube back transistor" hybrid structure is used: the front stage uses WE408A (EF92 / 6J1) vacuum tube, and the rear stage uses op amp + discrete components mainly composed of transistor-based buffer amplifier circuit. The amplifier has the sweetness as well as the sense of speed of stone machine.
2. The Little Dot LD1+ adopts aluminum alloy case structure and fine craftsmanship: the case adopts a secondary oxidation process with good finish and feel, and the electronic tube is equipped with aluminum alloy decorative ring.
3. The feature of this machine is that there are 4 electron tube switch inside, which are used to select different fore-level tubes: WE408A / WE403A, B / EF91, 92 / CV131, 138/5654 / EF95 / 6J1 and other electron tubes can be directly used by switch, so that users can get more fun to change tubes.
