Name: 6F6 Use: Metal tube type used in the audio output stage of ac receivers. It is capable of large power output with relatively small input voltage. Notes: Requires an octal socket and may be mounted in any position. It is especially important that this tube, like other power-handling tubes, should be adequately ventilated. |
