Tube Amplifier Headphone Amp P94573

Features: 1. pure hand made, the whole machine uses point to point welding 3. Use high power Z11 iron core Japanese EI type power transformer specially designed for this machine 4. Use 12AX7 and 12AU7 vacuum tubes for voltage amplification and phase inversion, use EL34 vacuum tube for AB1 push pull power amplification; provide triode and super linear selection function 5. peripheral power tube current adjustment button and current display header 6. infrared function remote control 7. boot mute delay function (about 30 seconds) 8. Japanese ALPS motor potentiometer 9. Easy to install plug in vacuum tube protection cover This machine replaces the vacuum tube model with the vacuum tube model. 12AX7 12AX7EH, ECC83, E83CC, CV4004, ECC803, 5751 12AU7 12AU7EH, ECC82, 5814, 6189, CV4003, EL34, 6CA7 technical parameter: rated output power: 20W (RMS triode working state) 35W(RMS super linear working condition) machine frequency response: 10HZ~40KHZ Total Harmonic Distortion: 1% (1KHZ) Signal to Noise Ratio: 90DB Input sensitivity: 260MV Input impedance: 100 KΩ Output impedance: 4Ω, 8Ω Headphone output impedance: 30Ω 300Ω Power supply voltage: ~230V±5% (50HZ) ~115V±5% (60HZ) machine size (WxDxH): (396 X 340 X 200) MM Vacuum tube: EL34X4, 12AU7X2, 12AX7X2 Net weight: 18KG Power consumption of the whole machine: 260W Bleutooth version part: Bleutooth chip: CSR8635 Bleutooth Specifications: BLUTOOTHV4.0 Support Bleutooth protocol: HFPV1.6, HSPV1.2, A2DPV1.2, AVRCPV1.4 Audio Performance: Support AAC, MP3, SBC, Stereo Transmission distance: Valid range 10 meters Power supply: 110V - 120V 60Hz/50Hz.(For United States) If you need to use it in Europe, there is The selector is inside the machine to set it to be 220V-240V ,It works well in Europe too.
