Description
The 6F4P (6Ф4П rus.) triode-pentode tube is designed for use in the output stages of video amplifiers and low-frequency power amplifiers (pentode section), in automatic gain control (AGC) circuits, and in preamplifiers of television and radio broadcast receivers (triode section).
6F4P is equivalent to tubes: ECL84, 6DX8 and 6DQ8.
