Psvane T-417 300B-T Reference Tube Pre-amplifier and Headphone Amp
Very clean and well maintained PSVANE T-417 Reference Tube Pre-amplifier and Headphone Amp with upgraded power tubes, a pair of Shuguang Treasure 300B-Z,
Other tubes are a pair of upgraded RAYTHEON JAN-5842's, a Psvane 12AX7 and a GE5670.
Wonderful sounding, excellent extension in both the bass and higher frequencies, this is a pre-amp that is truly deserving of the title 'Reference'!!!
This unit consists of two parts: amplification and power. The enlarged part is amplified by 1/255670, and the two 5842 are respectively output. The output has 600 ohm balanced output and unbalanced output. The balanced output uses a cassette socket and the unbalanced output uses an RCA socket. The power supply section has a 300B for high voltage rectification, and a 300B and a 12AX7 form a high voltage regulator. The power and amplification sections are connected by aviation plugs and cables. This set of pre-stages is used in high-end audio systems with strict matching requirements. It is recommended that the user select the T845 post-amplifier that the company is equipped with the machine. We have optimized the matching of the machine to make the machine perform better.
Balanced and RCA Single ended Outputs and 2 RCA Inputs.
