T-6B4G-SOVT Vacuum Tube - 6B4G, Sovtek
Sovtek 6B4G power triode tube. Made in Russia.
Sovtek is proud to announce the release of the Sovtek 6B4G vacuum tube. Unlike traditional 6B4G's, which consist of dual triodes connected in parallel inside the tube's envelope, the Sovtek 6B4G utilizes a single triode design with a Directly Heated cathode element. This updated design eliminates differential resistance loading common to other 6B4G's, yielding a much more reliable tube. In addition, the Sovtek 6B4G has a lower inter-electrode capacitance, offering a wider frequency response with high sound detail.
