Pentagrid Mixer Amplifier
The 6L7 Vacuum tube is a metal type used as mixers to
superhetrodyne circuits having a separate oscillator
stage as well as in other applications where dual
control is desirable in a single stage.
The two separate control grids are shielded from each
other and the coupling effects between oscillator and
signal circuits are very small. It requires an octal
socket.
