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. The Sovtek 6B4G is identical to the original 6B4G in appearance, electrical specs, and overall and connecting dimensions, yet it yields 40% higher power at 30% lower non-linear distortion levels.

The 6B4G has a heater current of 1 A and a plate current of 60 mA. Transconductance is 5.5 mA/V while the tube has an amplification factor of 2.2 and an output power of 3 watts.

Maximum plate voltage is 450 v while maximum cathode current is 100 mA.
