Voltage Pentode - Remote Cutoff (single) ·Pentode
6GK7
The 6GK7 is a high-gain, dual-control pentode designed for television video intermediate-frequency amplification. Its third grid permits sharp, semi-remote, or remote cutoff operation depending on circuit conditions, providing flexible automatic gain control and high amplification with very low control-grid-to-plate capacitance.
