Voltage Pentode - Remote Cutoff (single) ·Pentode

6M7G

The 6M7G is a remote-cutoff radio-frequency pentode with a metallized glass envelope, designed for variable-gain RF and intermediate-frequency amplification. Its indirectly heated cathode, 6.3-volt heater, and remote-cutoff characteristic make it suitable for receiver stages employing automatic gain control.
