Let everything follow the wind from Black Voice Tube Preamplifier plus SE 6P1 Tube Amplifier

Let everything follow the wind, the song is Cantonese one, and it is played from a tube preamplifier with 6N3(replacement US GE5670) plus 6N5P ( replacement GE 6080), plus single-ended 6P1 tube amplifier. Also, the tube amplifier is a headphone amplifier with 1W output.

And the music sourcing from Bluetooth receiver that is Bluetooth 4.2 version CSR64215, which is connected wireless with the  virtual CD player of notebook played.

Tube Headphone Amplifier with Black Voice

Tube Headphone Amplifier with Black Voice

The sound is grand and magnificent, open and wide; performance of each frequency point perfect! In particular, when the use of imported tube like as RCA6080 (or Beijing 6N5P tube), more delicate high-frequency, low frequency more powerful!

The circuit design of "Black voice " is very concise, whole unit only took three tubes, the input stage and amplified by the two pairs of polar transistor 6N3 (or 5670) to constitute SRPP amplification circuit, each one just only for a channel 6N3.The output stage is a low resistance dual triode 6N5P (available 6080 U.S. direct replacement) cathode follower constituted, the same every 1 / 2 6N5P responsible for one channel, nothing more. Plus several external RC components and the power section constitute all the circuits. The greatest feature of this unit is no output transformer, the transformer windings out of the two exchanges, a direct supply tube filament, another group rectified and simple multi-level RC Buck, after filtering for tube anode voltage. Although not using filter chokes, filament still used AC power supply. This tube earphone amplifier cannot hear the slightest hum, even when the volume is turned up no signal, the background is quite clean, showing excellent signal to noise ratio.
