6J5 Vacuum Tube – Octal Single Triode for Vintage Radio Audio & Oscillator Stages

The 6J5 is a single-section octal triode — effectively one half of a 6SN7 in its own envelope — used for straightforward audio gain or oscillator duty.

• Tube type: Triode
• Base: Octal 8-pin
• Heater: 6.3V AC, 0.3A
• Typical use: Audio amplifier and oscillator stages in vintage radios and early audio gear

Useful where a circuit calls for a single triode rather than a dual-triode envelope.
