Features:
Single-ended pure Class A tube Integrated amplifier The body of Willsenton R300B uses classic blue piano paint.
• Pure hand-made, Point to point manual welding.
• Two 274B(274B is better at high voltage, it is more stable) vacuum tubes are used for high-voltage rectification. 1pcs of 6SL7 and 2pcs of 6SN7 vacuum tubes are used for the voltage amplifier and preamp stage.
The power amplifier stage uses two Willsenton custom-made 300B vacuum tubes for single-end Class A power amplification.
• Reasonable internal structure, with fever circuit, high frequency is clear and detailed, full frequency is full, low-frequency dynamic is loose and powerful
• Use a square power transformer specially developed for this R300B tube amplifier
• Two wide frequency high-end EI type single-ended output transformers with high-end special
• Provide professional equipment input ports, R300B is equipped with multiple signal input ports, which can facilitate you to connect a variety of audio source signals, so that you can have different audio sources and different experiences
• Brushed aluminum alloy panel, using brushed panel, exquisite workmanship, comfortable feel, high-grade and elegant.
• Gold-plated port, a design that integrates quality and beauty, reduces signal loss, and has good conduction performance; the metal mesh cover can protect the beauty of the electronic tube, making it safer for users.
• Power on mute delay function, soft-start feature to prolong tube life (about 30 seconds).
• Infrared function remote control
• Use Japanese ALPS high-end potentiometer
• Peripheral power tube bias current adjustment function and power output level meter sensitivity switch
• Negative feedback circuit design
• Use thick silver-plated signal leads
• Headphones output 6.5mm jack
