The 6AW8A is a high μ triode and a sharp cut-off pentode. The design use was as a sync separator and video amplifier. The electrically identical 8AW8A has an 8.4 Volt 0.45 Amp heater.The RCA data_sheet describes the 6AW8A thus: 'miniature type used in television receiver applications. The pentode unit is used as an IF amplifier, video amplifier, AGC amplifier or reactance valve. The triode unit is used in low-frequency oscillator, sync-separator, sync-clipper, and phase-splitter circuits'.
Here the three wire grids can be seen. The open pitch of the suppressor grid contrasts with the fine pitch of the control grid. Both inner grids are wound on copper supports for good thermal conductivity.
