Single piece, not matched. The price applies to one tube.

Ultra-long life, top-quality construction, and superior sonics make it the finest 300B available today. Like the original Western Electric 300B, our 300BEH has the 8 course directly heated filament, 40 watt plate dissipation, classic large shoulder tube glass, and are available singly or in precision matched pairs. The 300B EH's plate curves and static DC characteristics (plate resistance, transconductance, mu) also exactly match the originals so you can drop them into any vintage or modern 300B amp and realize the finest performance of any 300B made today.

Single tube, not matched
The tube was previously installed and shows signs of use, but it is technically in perfect condition.

With a massive plate dissipation of 70 watts, the Tung-Sol KT150 is the most powerful octal beam tetrode ever produced. A pair of KT150s can allow an amplifier with a power output approaching 300 watts to be built.

The Tung-Sol KT150 glass envelope is a special egg shaped balloon that was developed to improve thermal dissipation and maintain a superior vacuum for the best sound. The fact that the glass envelope has no flat sides means the Tung-Sol KT150 has no problems with microphonics.

These 6SN7GTB NOS (New Old Stock) tubes originate from various manufacturers, including GE, Tung-Sol, Sylvania, and RCA. Being vintage items, these tubes may differ in labeling and construction. Some will be supplied in their original packaging (OVP), while others may arrive in neutral packaging.
