407-050 BRZHIFI Bluetooth Tube Amplifier 2x40W Hifi Power Amp Assembled 6H3 Tube + STK407-050
Description:
It is designed with STK407-050 power amplifier module. The circuit of this model is special, the quiescent current is not low, but the operating temperature is not high. The sound is clear, sharp and not frizzy. When paired with 6H3 tube, the vocal string music is charming and friendly to ears. Designed output power is 40W+40W at 6Ω, and the distortion is THD0.05%. Pushing general bookshelves or floor-standing speakers can achieve satisfactory results. As a comparative LM3886 power amplifier chip, 68W power is obtained under a 4-ohm load, and the power is only 38W under an 8Ω load, which is much lower than the 45W of STK407-050.
This machine is equipped with Bluetooth 5.0 and USB input. The shell of the machine is made of CNC aluminum alloy, and the middle heat sink is thick enough to dissipate heat, and the transformer cover can ensure as little interference as possible. The appearance of the whole machine is exquisite and compact, which is convenient to use.
There are 3-way to input, that is, Bluetooth, USB and wired inputs.
