Review GENERAL ELECTRIC Vintage Nos Valves Radio Tubes Vacuum Amplifier Tested Metal Ge

The NOs 12SG7 and 12SG7GT are dual triode vacuum tubes, specifically designed for use in radio amplifiers and audio applications. These tubes are part of the 12AX7 family, which is widely known for its excellent performance in various electronic devices.

The 12SG7 and 12SG7GT share the same electrical specifications, with a plate voltage range of 200 to 400V and a plate current of around 50 to 100 mA. However, the 12SG7GT is a high gain version, providing a higher amplification factor, making it an excellent choice for use in the driver stages of audio amplifiers.

The 12SG7 and 12SG7GT tubes are grown on a 9mm diameter, 6.3mm long glass base, featuring a metal filament and a triode-connected cathode. The glass envelope is made of hard borosilicate glass, providing excellent thermal shock resistance and durability.

The 12SG7 and 12SG7GT tubes offer a high input impedance, low output impedance, low microphonic sensitivity, and a wide frequency response, making them suitable for a wide range of applications. These tubes are known for their excellent sound quality, providing rich, warm, and detailed audio with a good dynamic range.

In summary, the NOs 12SG7 and 12SG7GT are high-quality dual triode vacuum tubes, offering excellent performance and durability for use in radio amplifiers and audio applications. Their high gain, low microphonic sensitivity, and wide frequency response make them an excellent choice for audiophiles and electronic enthusiasts seeking to build or restore vintage electronics or audio systems.

1. Authentic Vintage Experience: NOs (New Old Stock) tubes can provide a unique, vintage sound that is not replicated in modern solid-state devices.

2. Warm and Tube-like Sound: Vacuum tubes have a characteristic warm and rich sound, which is often preferred by audiophiles and musicians.

3. Durability: Vacuum tubes are known for their durability and long lifespan, making them a reliable choice for audio applications.

4. Customizability: Vacuum tubes allow for a high degree of customization and experimentation, giving users the ability to fine-tune their sound to their preferences.

1. Higher Cost: Vacuum tubes, especially NOs, can be more expensive than their solid-state counterparts.

2. Limited Availability: NOs tubes may be harder to find and more expensive due to their limited availability.

3. Maintenance: Vacuum tubes require more maintenance than solid-state devices, such as regular cleaning and replacement of parts.

4. Limited Power Handling: Vacuum tubes generally have lower power handling capacities than solid-state devices, which may limit their use in high-power applications.

NOs 12SG7/12SG7GT valves can provide a unique and authentic vintage sound that is often preferred by audiophiles and musicians. However, they come with a higher cost and require more maintenance than solid-state devices. If you are looking for a vintage sound and are willing to invest in the maintenance and potential replacement of parts, then NOs tubes may be a worthwhile investment. However, if you are looking for a more cost-effective and low-maintenance option, then solid-state devices may be a better choice.

If you are interested in trying out vacuum tubes for your amplifier, I would recommend starting with a lower-cost option and experimenting with different tube types to see what works best for you. Once you have a better understanding of your preferences, you can consider investing in higher-quality NOs tubes if you are willing to accept the additional cost and maintenance requirements. Alternatively, you can consider purchasing reissued or reproduced tubes, which can offer similar sound quality at a lower cost. Ultimately, the choice of whether to use vacuum tubes or solid-state devices depends on your personal preferences, budget, and audio needs.

Details:

I tested tubes on my calibrated encore mighty mite tube tester, which shows them strong and in new condition.

Those vacuum tubes were made in USA as indicated on the tube.
