Review CUNNINGHAM Rare Detector Ge 300 Vacuum Tube H14 Untested Radio Valve Vintage

The C-300 Cunningham Detector, model number GE 300, is a vintage radio valve or vacuum tube that holds a significant place in the history of audio technology. This Cunningham detector, specifically the GE 300 variant, is a testament to the engineering prowess of the mid-20th century.

The C-300 is a Cunningham detector tube, named after its inventor, William Cunningham. It was designed primarily for use in early radio technology, specifically as a detector in radio receivers. The detector converts the radio frequency (RF) signal into an audio frequency (AF) signal, which can be amplified and played through a speaker.

The GE 300 variant of this tube is manufactured by General Electric, a renowned American multinational conglomerate that was a pioneer in the field of vacuum tube development. The GE 300 tube is known for its robustness and reliability, making it a favorite among vintage radio enthusiasts.

The C-300 GE 300 tube is a triode vacuum tube, meaning it has three electrodes: the cathode, anode, and grid. The cathode emits electrons, which are controlled by the grid. The anode collects these electrons and allows them to flow, creating an electric current. In the context of a radio receiver, this current represents the audio signal.

The C-300 GE 300 tube operates at a voltage of 300 volts and a current of 25 milliamperes. It has a plate resistance of 2500 ohms and a grid leak resistance of 100 kilohms. These specifications ensure that the tube can handle the signals it's designed to process without distortion.

In terms of physical dimensions, the C-300 GE 300 tube is approximately 7 inches long, with a diameter of 1.5 inches. It is housed in a glass enclosure, which protects the internal components and provides a vacuum to prevent the electrons from colliding with the walls of the tube.

In conclusion, the C-300 GE 300 vacuum tube is an essential piece of vintage radio technology. Its robust construction, reliable performance, and historical significance make it a valuable asset for radio enthusiasts and collectors. Whether you're restoring an antique radio or building a vintage AM radio from scratch, the C-300 GE 300 tube is an indispensable component.

Details:

I got some advice from an er about testing for continuity using old multi-meter have. Always happy to help people out with questions. Please see shipping details for listing or ask questions if you are unsure. Most items are sent via USPS first class or priority mail.

Since this is delicate, I will do my best to wrap it well with bubble in a sturdy box. Always happy to answer questions just send me a message. This listing: offer is for an untested Cunningham detector C-300 vacuum tube.

All information given is to the best of my knowledge. Looks okay to me, but I am barely a novice when it comes vacuum tubes. Sometimes heavier items are sent with other options.

I set it to ohms 1k and touched pins see if the needle would move. Colors may be slightly different from actual item due to lighting, screens being used view the item, and other variables that I am unable control.

On the side of base is stamped Cunningham detector model C-300 patented licensed for amateur or experimental use only tip and glass are in good shape. I used a lightly damp cloth to clean the dirt dust away, still some left. Looks like it has a brass base, with 4 pin connection.

About my photos: I shoot all of own photos. The needle did not move when two of pins were connected. I do not know the history of this item and have knowledge to test.

All photos are originals. Therefore it is being sold as untested. Inside the glass on element is written 14 one side and f other.

Take this info as you see fit, I still consider untested and am selling is.
