Review SYLVANIA Vacuum Tube Single Nos Nib Valvola Lampe Hre Valve Qty

The 12BF11 Sylvania Vacuum Tube is a single-noble-gas-filled valve that harks back to the golden age of audio technology. This vintage tube is a testament to the craftsmanship and innovation that characterized the early days of audio engineering.

The 12BF11 is a triode indirectly heated vacuum tube, designed to operate at a filament voltage of 6.3 volts and a plate voltage of up to 300 volts. It has a conveniently small diameter of 9.5mm, making it a versatile choice for various audio applications.

This valve is filled with a noble gas, which helps to reduce the risk of arcing and prolongs the life of the filament. This feature, combined with its robust construction, ensures reliable performance even under heavy load conditions.

The 12BF11 Sylvania Vacuum Tube is a popular choice among audiophiles and vintage audio enthusiasts due to its warm, rich sound signature. It is widely used in high-fidelity audio equipment, such as vintage amplifiers, preamplifiers, and radio receivers.

In summary, the 12BF11 Sylvania Vacuum Tube is a high-quality, vintage component that offers a unique and authentic audio experience. Its robust construction, reliable performance, and warm sound signature make it an excellent choice for any audio enthusiast looking to add a touch of vintage charm to their audio setup.

1. Authenticity: With a New Old Stock (NOS) vacuum tube, you are buying a tube that has been in storage since its manufacture and has not been used or tested. This ensures that the tube is in its original condition and has not been tampered with or degraded over time.

2. Quality: Sylvania is a well-known and respected brand in the vacuum tube industry. The 12BF11 tube is a high-quality tube that is often used in audio equipment and other electronics.

3. Durability: Vacuum tubes, when properly cared for, can last for many years. A NOS tube is likely to be in better condition than a used tube, which can lead to longer tube life.

4. Sound quality: Vacuum tubes are often preferred for their warm, rich sound in audio equipment. A 12BF11 tube can provide a rich, full sound that is difficult to achieve with solid-state electronics.

1. Cost: NOS tubes can be more expensive than used tubes. This is due to the fact that they have been in storage for many years and are in high demand by collectors and audiophiles.

2. Availability: Not all NOS tubes are readily available. Some tubes, such as the 12BF11, may be more difficult to find and may require searching online or contacting specialty retailers.

3. Compatibility: Vacuum tubes can be specific to certain types of equipment. Before purchasing a 12BF11 tube, it is important to ensure that it is compatible with your equipment.

4. Maintenance: Vacuum tubes require more maintenance than solid-state electronics. They can be sensitive to temperature and humidity, and they may need to be replaced more frequently than solid-state components.

If you are an audiophile or a collector, a 12BF11 Sylvania Vacuum Tube Single NOS Valvola Lamp can be a worthwhile investment. The tube's high quality, authenticity, and potential for delivering a rich, full sound make it an attractive option for those looking to improve their audio equipment. However, the tube's cost and potential difficulty in finding can be drawbacks for some. Before making a purchase, it is important to do your research and ensure that the tube is compatible with your equipment and that the cost is within your budget.

If you are looking to purchase a 12BF11 Sylvania Vacuum Tube Single NOS Valvola Lamp, I would recommend doing your research and shopping around to find the best price. It is also a good idea to familiarize yourself with the maintenance requirements of the tube and to ensure that it is compatible with your equipment before making a purchase. Overall, a 12BF11 Sylvania Vacuum Tube can be a great addition to your audio equipment, but it is important to approach the purchase with a critical eye and a clear understanding of your needs and expectations.

Details:

Testing: I test all tubes that sell in one way or another, will state untested. It give a percentage value of gm for the tube under test and checks shorts grid emissions.

I also use a tectonics curve tracer for testing tirades. Do not handle the tubes or hold them from cylinder. This is an honesty issue. I don't check each and every tube for noise or tone.

Always hold them from the ends. They average 5.

I have 40 tube testers. Sound quality is tremendously subjective.

You can calibrate a vintage tube tester all want.

The voltage needs to be 6. This is a mutual conductance tester.

On my tester a b k 747 tester: below 55 bad 55-65.

I will bend over backwards to make sure that you are a happy customer. Tube hunter vacuum gems these are the specifics of tubes for sale: manufacturer: Sylvania production city: USA type: 12BF11 designation: nos nib year: varies month: varies date code match single silk screen condition: 100 mica: 2 plates: grey gm 120 pair quad multi: fetter: fetter this offer is one.

If we sent the wrong tube will of course pay for return shipping. This is subjective and it too time consuming. And all the angels sang because heavenly music was playing it turned way up.

The lines show how tube conducts throughout that range. The tectonics curve tracer gives values within 3 of actual value. One evaluation is a screen shot of the tube with high voltage applied to plate.

Every tester I have ever bought is below 6 volts when selecting. I don't guarantee or imply anything else.

The curve tracer steps tried through 10 gate grid voltage s starting with 10 volts and going. At volt the tube is max conduction and top line on display. On all of them I have an outside regulated dc power supply that feeds the tube tester correct heater voltage .

I will work with you in good faith if there are any problems, or unsatisfied way. All tubes are tested for shorts, continuity, and emissions. It is easy at that point to take where top line intersects the plate voltage , find lamp level and compare data sheet.

Vintage tube testers almost always, due to age, have very low heater voltage s. The very best portable testers only can approach 10 accuracy.

It can be wiped off and destroyed very easily. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I have a b k 747 tube tester.

I give a number of evaluations for tubes. I give those numbers for you in the item condition box.

They say have a calibrated tube tester. If you are buying only one item this will not be an issue.
