The 6SN7GT-A-B tubes are designed with a 9-pin base and operate at a voltage of 6.3V with a plate current of 100mA. They have a heater voltage of 6.3V and a heater current of 450mA. The tubes have a maximum rated power output of 10 watts and a maximum plate dissipation of 60 watts.
The glass envelope of the 6SN7GT-A-B tubes is made of high-quality borosilicate glass and is sealed with a metal grid to prevent air from entering the tube during operation. The aluminum base is securely attached to the glass envelope with a metal cap screw, ensuring a reliable connection and long-term performance.
The 6SN7GT-A-B tubes are manufactured to strict quality control standards, ensuring that they meet or exceed the specifications set by the original manufacturers. The tubes are tested for leakage, heater voltage, heater current, plate current, and plate voltage, ensuring that they are in good working order before they leave the factory.
In summary, the 6SN7GT-A-B 6SN7 vacuum tubes are a high-quality and versatile addition to any audio system. Their dual triode design, excellent performance, and reliable construction make them a popular choice for audiophiles and electronics enthusiasts alike.
