RF tubes, also known as vacuum tubes or valves, are essential components for many ham radio operators, especially those running older equipment or building high-power linear amplifiers. These tubes are critical for generating and amplifying radio frequency signals across various bands, from HF to VHF, enabling strong QSOs and effective DX operation. Many hams prefer the robust performance and unique characteristics of tube-based transceivers and amplifiers for their stations.

This category lists suppliers offering a wide range of RF tubes, from common types used in vintage amateur radio gear to specialized power tubes for high-QRO amplifier projects. Operators can find new old stock (NOS) tubes, often from manufacturers like Svetlana, and even Russian-made tubes for specific amplifier designs such as the GU-43B or GS-35B. Resources also include suppliers for related components like sockets, capacitors, and even manuals for tube testers, supporting both restoration projects and new homebrew equipment builds.
