Description

Features: Refer to the new design of domestic and foreign circuits, using the classic name of the noble voice 300B for power amplification, 6N8P preamplifier, shuguang rectifier tube, Thick aluminum alloy panel, Classical double VU meter, Solid aluminum knob, 3 channels of audio input switching, Fever grade pure copper plated socket Pure copper plated crystal terminal, Imported fever-grade capacitors Performance parameters: Rated output power: 9W × 2 Frequency response: 20Hz--25KHz Total harmonic distortion: < 1% (1kHz) Input sensitivity: 500mV--2000mV Input impedance: 100KΩ Output impedance: 4Ω, 8Ω Signal to noise ratio: 88dB Power Supply Voltage: AC 100V - 240V / 50Hz-60Hz Volume (width × depth × height): 370 × 250 × 200mm Net weight: 19kg Package weight: 20Kg Pre-stage tube: 6N8P × 2 /6H8C X2 After-stage power tube: PSVANE 300B-se×2 Rectifier: shuguang 5Z3PAT/5U4G Tube Amplifier Precautions: 1. Tube amp must connected with speakers before turning ON. Strictly prohibit send signals to amp without connected loads(speakers) or load short circuit when the switch is ON. 2. Too high or too low power supply voltage does irreversible harm to the amp,preferably less than 5% of the specified voltage. If your mains voltage exceeds this value, often best to use with the AC power supply. 3. Temperature is higher when tube amps working, placing attention to ventilation, cooling. 4. In the boot or just shut down for a period of time (within 30 minutes) Do not spill liquid on the tubes. 5. You should take about 100h time to operate the amp.RUN-IN to the amp gives it's best and stable sound.so during the first 100h use time the sound maybe is not the best,you can also use your own run-in method. 6. If you donot sure how to plug the tubes, please contact us before try it Speakers connection: All tube amplifier used with stereo mode: L(left) and R(right) speakers. Normally there are 6 speaker cable connectors: +8L, +4L, -0L, -0R, +4R, +8R Example: +8L and -0L are for connecting with your Left 6-8ohms speaker -0R, +4R is for connecting with your Right 4ohms speaker
