🔊What is 5C4S Tube?
The 5c4s rectifier tube converting alternating current (AC) to direct current (DC). This tube features two anodes (positive electrodes) and one cathode (negative electrode) that are heated by a filament. Rectifier tubes like the 5c4s find extensive use in power supplies for radio and audio equipment, as they are capable of handling high voltages and currents. Amplifiers, receivers, transmitters, and oscilloscopes are examples of devices that employ the 5c4s tube to fulfill their rectification needs.

WHY DOES 5C4S CALL “COBRA”?
The distinction between a 5C4S figure flask and a soft rectifier tube lies in their nature and characteristics. The 5C4S figure flask refers to a specific tube model with a unique cobra shape. On the other hand, a soft rectifier tube pertains to a general category of rectifiers known for their soft recovery characteristic.

💡5C4S VS 5Z4
The 5c4s and 5Z4 are vacuum tube rectifiers renowned for their ability to convert AC to DC. Despite originating from different countries, the USSR and China respectively, they share similar specifications and are functionally equivalent. These tubes feature an octal base, a glass envelope, an oxide cathode, and two anodes. With a capacity to handle up to 500 V of anode voltage and up to 375 mA of anode current.
🎼5C4S VS 5Z4GT
Indeed, the 5Z4GT is another rectifier tube capable of converting AC to DC. It shares similar specifications and equivalence with the 5C4S tube. While the 5C4S originates from the Soviet Union, the 5Z4GT is a British tube. Both tubes feature an octal base, a glass envelope, an oxide cathode, and two anodes. They can take anode voltages up to 500 V and anode currents up to 375 mA. These shared characteristics make them versatile options for rectification purposes in various electronic circuits, delivering reliable performance for their intended applications.
5C4S VS 5U4C
The both vacuum tubes have similar specifications and are equivalent to each other, as well as to the 5Z4, CV1863 and 5Z4GT tubes.

🏭5C4S Tube Manufacturers:
The 5c4s tube is a type of vacuum tube rectifier that was produced by various manufacturers in different countries. Some of the biggest manufacturers that created such tubes are:
- Novosibirsk– a Russian factory that was founded in 1942 and specialized in producing radio tubes, semiconductors, lasers and other electronic devices. They made 5c4s tubes with a glass envelope and an octal base, equivalent to the 5Z4, CV1863 and 5U4C tubes. They also made an old type figural bulb version of the 5c4s tube.
- Foton– another Russian factory that was established in 1938 and focused on making vacuum tubes, lamps, photo cells and other optical products. They also produced 5c4s tubes with a glass envelope and an octal base, similar to the Novosibirsk ones. They had a logo of a light bulb with rays on their tubes.
- Tesla – a Czechoslovakian company that was founded in 1921 and became one of the largest manufacturers of electronic components in Europe. They made 5c4s tubes with a metal envelope and an octal base, equivalent to the AZ11, RGN2004 and AZ4 tubes.
💸Average prices:
5Z4 tube average price ranges from about $15
CV1863 Tube Price could range from approximately $15 – $27 USD
5C4S Tube price ranges in average from about $6-7 USD
