Glass octal type used as mixers to superhetrodyne circuits having a separate oscillator stage as well as in other applications where dual control is desirablein a single stage.
Source ........................................ RCA DS 08/05/35
The two separate control grids are shielded from each other and the coupling effects between oscillator and signal circuits are very small. Requires octal socket.
