Description Report Item Thank you very much for visiting  Electronic Tube Specialty Store Wishing you a pleasant shopping experience Brand new  Gold Lion PX300B Vacuum Tube Upgrade 300B 300BT 300BG 4300B WE300B for HIFI Audio Valve Electronic Tube Amplifier Kit DIY Factory Genuine Precision Tested and Matched Quad In the actual audition of this tube, PX300B gives people the impression that overtones are very rich, string details reappear very completely, and the texture is dense and sweet. The second impression is that it can emit a more touching IF than the 2A3. So far, I think the flagship status of PX300B should have been confirmed. The low frequency that ordinary triode players don't care about, the PX300B is very competent at this point. The deep and solid low frequency can match the impression of the Web 300B. Another advantage of this tube is that the tolerance of filament voltage is much better than that of the old tube. The pressure resistance is also much higher. You can save a lot of trouble whether you upgrade the old pipe or install the player's own machine.
