The 8AW8A is a high μ triode and a sharp cut-off pentode. The design use was as a sync separator and video amplifier. The 8AW8A has an 8.4 Volt 0.45 Amp heater. The 6AW8A is an identical device but has a 6.3 Volt 0.6 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'.
The image shows the triode section behind the C or RCA and the pentode anode fixing notches are seen behind.
The thin glass tube envelope is 20 mm in diameter, and excluding the base pins is 53 mm tall.
Reference: Datasheet. Type 8AW8A was first introduced in 1956.
