Description
Hot Little Dot LD1+ Headphone Tube Amplifier Pre- amp Vacuum Tube Headphone Amp
Features:The front stage adopts the vacuum tube,and the post-stage transistor is the main buffer amplifying circuit,which has both the sweetness of the biliary and the speed of the stone machine.
In the circuit design using the so-called "Pre-Tube Back Stone" mixed structure: the former use of WE408A (EF92 / 6J1) vacuum tube, after the use of op amp + discrete components to the main component of the buffer amplifier circuit, both the machine Of the sweet, but also a sense of speed of stone machine.
Small point I + aluminum chassis structure, fine craft: chassis with finish and feel a good secondary oxidation process, the tube is equipped with aluminum alloy decorative ring.
The machine is characterized by four internal tube switch, used to select a different pre-tube: WE408A / WE403A, B / EF91, 92 / CV131,138 / 5654 / EF95 / 6J1 and other tubes can be switched directly through the switch , So that users get more fun from the exchange.Main Specifications:
