6J5 and 6J5GT Vacuum Tube New and Used

- Description
- Specifications
The 6J5 and 6J5GT are medium-mu single triode vacuum tubes designed for general-purpose voltage amplification, phase inversion, and detector/oscillator service in vintage radio receivers and audio amplifiers. The standard 6J5 features a metal envelope construction for superior RF/AF shielding, while the 6J5GT (Glass Tubular) utilizes a compact T-9 glass envelope. Electrically identical, both variants represent a single triode unit equivalent to one section of the 6SN7GT dual triode. They operate on a 6.3V heater and fit standard 8-pin octal sockets. Available NOS and tested used.
