AUDIO VALVES: KT63 6F6 ARP17 CV1186 CV1911 NR85 AUDIO PENTODE

Type 6F6 is a general-purpose audio output pentode intended for domestic and car radios. Its output is  similar to that of the  6V6 but it was more sensitive with the ability  to be driven directly from the detector output, thus saving one stage of audio amplification - a boon for car radio design. 

If a pair are used as an audio amplifier in push pull class A, 10.5 Watts are possible with 3% distortion.  The equivalent type KT63 is a beam tetrode.    Type 6F6 was first introduced in 1936.
