Output beam Power Audio Tetrode
Russia made
6P3S Output beam tetrode in a glass shell with an octal base. Designed for operation in the output stages of low-frequency power amplifiers. The 6P3S output tetrode is used in single-ended and push-pull output stages of receivers and low-frequency amplifiers. Can be used as a high-frequency generator in tape recorders, transmitting devices and other general-purpose equipment. Indirectly heated oxide cathode. Works in any position. Available in glass design. 6-pin octal socket with key.
Overall dimensions of the 6P3S tetrode: - lamp height - 110 mm; - lamp diameter - 38.3 mm.
Weight no more than 70 g.
Operating time no less than 1000 hours.
