Features:
Single-ended pure Class A tube Integrated amplifier
The body of Willsenton R300 PLUS use classic Black piano paint.
• Pure hand-made, Point to point manual welding.
• Two Willsenton custom-made 5AR4 vacuum tubes used for high voltage rectification. 1pcs of TUNG-SOL 6SL7 and 2pcs of Willsenton 6SN7 vacuum tubes are used for the voltage amplifier and preamp stage. TUNG-SOL 6SL7 can be better optimized circuit. 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 R300 PLUS tube amplifier
• Two wide frequency high-end EI type single-ended output transformers with high-end special. Optimized production process of output transformer with Z11 imported iron core.
• Provide professional equipment input ports, R300 PLUS 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 a new Remoter CNC in one block aluminum alloy, more convenient to change batteries.
• 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
