Vacuum Tube - 6669 / 6AQ5A, Tetrode, Beam Power
New-Old-Stock (NOS) tube.
The 6669 is a miniature beam-power pentode designed for use as an audio-frequency power amplifier. Its electrical characteristics are essentially equivalent to those of the 6AQ5.
Intended specifically for use in mobile communications equipment, the 6669 may be operated without serious degradation under normal variations in supply voltage as encountered with automotive electrical systems. Also consistent with the requirements of this equipment, the tube is capable of withstanding appreciable on-off cycling.
