LittleDot LD_4P1S Electronic Tube Headphone Amplifier 10W+10W Power Amplifier 2-In-1 Audio Amplifier
Description:
- This machine adopts a direct heating electronic tube: 4P1S. This is a good sound tube, known as the "Little 300B".
- This amplifier adopts a push-pull circuit, and due to the mutual cancellation of DC magnetic fields, there is no air gap and it will not cause magnetic saturation. In this way, the output transformer of the magnetic circuit closed-loop can be designed.
- From the perspective of anti-interference performance: non closed-loop magnetic circuits are easily affected by external magnetic field interference. After adopting closed-loop magnetic circuits, even if the output transformer is placed together with the power transformer, its noise will be more than half smaller than that of a split single ended Class A. In this way, the chassis becomes more compact, and for low resistance and high sensitivity headphones, there is no background noise.
- This amplifier adheres to the consistent principle of using materials: the input adopts for Swedish Lundahl transformer; The coupling capacitor adopts for German Mundorf capacitor; The front electronic tube adopts sound tube: for Russian 6H2N-EB; The output transformer adopts a Japanese Z11 iron core in a professional factory processing mode, which has achieved more accurate impedance matching. The chassis still adopts a whole aluminum alloy CNC hollow and carved scheme, which improves the stability of the entire machine.
- The volume of this device is not very large, but due to the use of a push-pull circuit, the maximum output power can reach 10W+10W, making it easy to drive difficult to drive flat headphones and direct drive speakers.
