A Rare Early Triode for Pre-War Radio RestorationThe Type 1005 is an early vacuum tube from the pioneering era of radio — a period when tube designations were still being standardized and each manufacturer brought its own engineering philosophy to the design. Tubes of this type were used in early broadcast receivers and experimental radio equipment of the late 1920s and early 1930s, making them essential parts for restorers working on the oldest and rarest sets in the hobby. Finding a functional example today is a genuine challenge, and having a tested, working tube in hand is the difference between a restoration that plays and one that sits on a shelf.Tested and Ready to InstallEvery Type 1005 we sell is individually inspected before it ships — checked for emission and functionality. You receive a tube that is ready to install and perform. One tube per order.

The Type 1005 is one of those parts — rare, correct, and increasingly difficult to source. If your set calls for it, don't wait. Stock is limited and these tubes are not being manufactured again.Specifications: Type: Early triode (pre-war era) Application: Early broadcast receivers, experimental radio equipment, pre-war restoration Condition: Tested and inspected Includes: 1 tube per order Premium brands available: +20% (inquire) Tested used tubes available: −20% (inquire) Note: The product photo is a representative example.
