6AG5
Sharp-Cutoff Pentode

EIA Base & Outline

EIA Base: 7BDEIA Bulb: 5-2
Source ........................................ RCA RC-29 - 1975

Application

Source ........................................ RCA RC-29 - 1975
Miniature type used in compact radio equipment as an rf or if amplifier up to 400 MHz. Tube requires miniature 7-contact socket and may be mounted in any position.

Source ........................................ RCA RC-29 - 1975
The two cathode leads facilitate isolation of the input and output circuits thus helping to minimize degeneration.
