Review GENERAL ELECTRIC Vintage Portable Radio Tube Type Model #p-673

The General Electric P-673 is a high-performance vacuum tube, specifically designed for use in high-frequency applications such as radio transmitters and receivers. This tube falls under the category of a pentode, which means it has five active components inside the glass envelope.

The P-673 is known for its excellent electrical characteristics, including a high plate current capacity, low plate dissipation, and high gain. It operates at a fixed frequency of approximately 100 MHz and is particularly suitable for use in medium and high power amplifier circuits.

The tube's anode is made of thoriated tungsten, which ensures good thermal conductivity and a long operating life. The cathode is coated with a thin layer of barium oxide, which facilitates the emission of electrons and helps maintain a stable and consistent current flow.

The P-673 tube features a robust construction with a large glass envelope and sturdy metal base. It is designed to withstand high voltage and power levels, making it suitable for use in demanding applications. The tube also has excellent stability, with a low microphonic response and a low level of mechanical vibration.

The tube's electrical specifications include a plate voltage of 1250 volts, a grid voltage of -110 volts, and a plate current of up to 1.5 amperes. It has a maximum power output of 3 watts and a gain of approximately 30.

The P-673 tube is a reliable and versatile component for use in a wide range of radio frequency applications. Its high performance and robust construction make it an essential component for radio transmitters and receivers in various industries, including broadcasting, military communication, and amateur radio.

When used in a well-designed circuit, the P-673 tube can provide excellent signal amplification, ensuring clear and strong radio transmissions. It is also known for its long operating life, making it a cost-effective solution for high-frequency amplification needs.

Overall, the General Electric P-673 is a high-performance vacuum tube that offers excellent electrical characteristics, a robust construction, and a long operating life, making it an essential component for high-frequency radio applications.

Buying a General Electric P-673 radio tube can be an interesting choice for those who are into vintage radio restoration or for those who have a specific need for this type of tube in their audio equipment. Here are some pros and cons to consider before making a purchase:

1. Authenticity: The P-673 tube is a classic piece of electronic history. It was widely used in various radio designs from the 1940s to the 1960s. owning one can add value to your collection and bring a sense of nostalgia.

2. Sound Quality: Many audiophiles believe that vacuum tubes, including the P-673, produce a warmer and more natural sound compared to solid-state components. This can be especially noticeable in older radios where the tube amplifier stage is the primary driver.

3. Durability: Vacuum tubes, when properly maintained, can last for a long time. The P-673 tube, in particular, is known for its reliability and robustness, making it a good choice for those who want a long-lasting component.

4. Repairability: Since the P-673 tube is an older design, it may be more straightforward to repair than modern components. Replacement parts and repair services are readily available, making it easier to fix any issues that may arise.

1. Power Consumption: Vacuum tubes consume more power compared to solid-state components. The P-673 tube, for example, requires a filament voltage of 6.3 volts and a filament current of about 300 milliamperes. This can lead to higher electricity bills and may not be an ideal choice for those looking to save energy.

2. Size and Weight: The P-673 tube is larger and heavier than modern components. This can make it more difficult to integrate into modern equipment and can also increase the overall weight of the device.

3. Fragility: Vacuum tubes are delicate components that require careful handling. They can be damaged if dropped or subjected to high temperatures or voltages. This can make them more prone to failure and may require more maintenance compared to solid-state components.

The General Electric P-673 radio tube is a classic component with a rich history and a unique sound quality. It is known for its durability, repairability, and reliability. However, it also has some drawbacks, such as higher power consumption, larger size, weight, and fragility. Whether or not to buy a P-673 tube ultimately depends on your specific needs and preferences. If you're looking for a vintage component with a warm sound and a sense of nostalgia, then the P-673 tube may be a worthwhile investment. On the other hand, if you're looking for a compact, energy-efficient, and low-maintenance component, then a solid-state alternative may be a better choice.

If you're interested in buying a General Electric P-673 radio tube, I would recommend doing thorough research on the specific model you're considering and the intended use case. Make sure that you have the necessary equipment and knowledge to properly handle, install, and maintain the tube. Additionally, consider purchasing the tube from a reputable dealer to ensure that you're getting a genuine and functioning component. Finally, be prepared for the additional costs and considerations that come with owning a vintage vacuum tube.

Details:

Was a display item. The shipping costs for USPS, UPS and FedEx have risen again so if you are buying something similar to an item purchase a while or some time ago, the increase is not my doing nor attempt profit on. Please inquire to shipping costs prior buying. Please inquire as to cost before buying.

Sold as pictured and as-is. Although the final weight isn't known until boxing is complete, majority of times it spot on or more meaning overage comes out my pocket. Sold untested.

I would rather get the item to you safely than skimp and risk damage.
