6FV8
Medium-Mu Triode - Sharp-Cutoff Pentode

EIA Base & Outline

Application

Source ........................................ RCA RC-27 - 1973
Miniature type used in color and black-and-white television receiver applications. Especially useful as combined triode oscillator and pentode mixer in vhf television tuners.

Source ........................................ RCA RC-27 - 1973
Requires miniature 9-contact socket. Except for basing arrangement and grid-1--to-plate capacitance of pentode unit, this is identical to 6U8A.
