Willsenton R200 32W+32W Vacuum Tube Amplifier Bluetooth Vacuum Tube Amp (Black) w/ 5881 Vacuum Tubes

Willsenton R200 32W+32W Vacuum Tube Amplifier Bluetooth Vacuum Tube Amp (Black) w/ 5881 Vacuum Tubes

Description:
The R200 series utilizes four 5881 vacuum tubes for class AB1 push-pull power amplification, followed by one 12AX7 and two 6N1 tubes for signal amplification and driving, achieving an output power of 32W per channel.

This series adopts a pure vacuum tube design and is manufactured with manual soldering processes. It includes an external, independent BIAS ADJ current monitoring meter and adjusting BIAS monitoring functions, which helps maintain the vacuum tubes in optimal condition at all times. Additional features include a 30-second silent delay function, ALPS potentiometers, Bluetooth 5.0 connectivity, a headphone output function, and easy-to-install plug-in vacuum tube protective covers.

Advantages:
- The body is made from aviation-grade aluminum alloy with piano paint.
- The external independent BIAS ADJ current display meter and current adjustment points.
- High-grade ALPS motorized potentiometers made in Japan.
- CNC-machined copper terminals plated with gold are aimed at further noise reduction and upgrades.

Features of R200 Series:
- Aluminum: The body is made from aviation-grade aluminum alloy
- Manual Soldering: We employ artisanal hand-soldering techniques to solder each component manually
- 30s Mute Delay: The high-voltage mute delay can effectively protect the vacuum tubes
- Potentiometers: We use high-grade ALPS potentiometers that are made in Japan
