TOP Qing 300B High-Power 300B Vacuum Tube, Solid Bass, Full-Bodied Sound, Rich Musical Tone (1 pair)

1. Higher Power Output: While standard 300B tubes deliver around 8-9W, the Qing 300B stably outputs approximately 11W, resulting in a significant increase in sound pressure level when installed.
2. Tighter, More Solid Bass: Equipped with a metal carbonized anode featuring low resistivity and excellent heat dissipation, the Qing 300B provides ample current supply for low-frequency signals, with a large anode current rating of 130±10mA.
3. Uncompromised Sonic Refinement: A  electrode design ensures the tube operates within its linear region even with increased current output, fully retaining the iconic smooth, lush, and warm tonal character of the 300B
4. Dynamic and Punchy Performance: The high current output allows the Qing 300B to handle symphonic and complex musical passages with far greater ease than conventional 300B tubes, delivering precise soundstage imaging and clarity at high sound pressure levels without muddiness.
