Willsenton R300 Plus 8W+8W Vacuum Tube Amp 300B Single-Ended Class A Integrated Amplifier (Silver)

Willsenton R300 Plus 8W+8W Vacuum Tube Amp 300B Single-Ended Class A Integrated Amplifier (Silver)

Description:
This R300 Plus series uses two 300B vacuum tubes for Class A single-ended power amplification, accompanied by one 6SL7 and two 6SN7 vacuum tubes for signal amplification and driving. It employs two 5AR4 vacuum tubes for full-wave rectification, achieving an output power 8W per channel.

Additionally, this series features handcrafted point-to-point wiring, a body and transformer cover finished with high-grade piano lacquer, a headphone output function, an external, independent BIAS ADJ current monitoring meter, a 30-second silent delay, headphone output capability, original motorized potentiometers for ALPS, and pure post-stage input functionality. It allows for independent pre-stage signal input.

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 motorized potentiometers made in Japan
* CNC-machined copper terminals plated with gold are aimed at further noise reduction and upgrades

Features:
* Aluminum: The body is made from aviation-grade aluminum alloy.
* 30s Mute Delay: The high-voltage mute delay can effectively protect the vacuum tubes
* BIAS ADJ: The high-end external, independent BIAS ADJ current display meter
* Manual Soldering: We employ artisanal hand-soldering techniques to solder each component manually.
* Quality Potentiometers: We use high-grade potentiometers made in Japan
* Power Amp Mode: We have added a power amp function to this series, allowing you to use your preamp

Sound of R300 Plus Series:
* Classical: This series has made every effort to restore classical music instruments, live performance ambiance, and vocal nuances.
* Pop/Contemporary: This series has made the greatest effort to achieve the mid-frequencies and high-frequency vocals needed for pop music.
* Symphonic/Live: This series makes the utmost effort to reproduce the sound stage and more wider dynamic range of live music faithfully.

Vacuum Tubes of R300 Plus Series:
* We use only high-quality vacuum tubes for our products!
* This series utilizes two 5AR4 vacuum tubes for full-wave vacuum tube rectification in the high-voltage section; the pre-stage employs one 6SL7 vacuum tube (for TUNG-SOL) for amplification and two 6SN7 vacuum tubes as the driver. And the power amp uses two 300B vacuum tubes for Class A power amplification. Every component is meticulously hand-wired and soldered, offering effective isolation and shielding. And its body is finished with piano lacquer. In this way, perfection is more fully achieved.
