• ONE YEAR WARRANTY. Willsenton R300 PLUS is an integrated Amplifier, it is a Power Amplifier too (there is a group Power amp input), it is a Headphones amp, too.
• Pure hand-made, Point to point manual welding.Single-ended pure Class A tube Integrated amplifier
• The body of Willsenton R300 PLUS use classic Black piano paint.
• Use a new Remoter CNC in one block aluminum alloy, easy to change the battery, and looks nicer.
• The high voltage uses two customized 5AR4 vacuum tubes for full-wave rectification.The front stage uses an imported Tung-Sol 6SL7 GT for amplification and two former Soviet 6SN7 vacuum tubes for push.The rear stage uses two customized 300B vacuum tubes for single-ended Class A power amplification.
• Simple troubleshooting: If you hear noise from your speakers. 1.Please try removing all the tubes and reinstalling them one by one to see if the problem exists. If the problem persists, proceed to the next step. 2. Please confirm which channel is coming from (left or right, or both).If the noise is coming from one side, please try switching the tubes of the left and right channels to check for tube damage.
