Remote-Cutoff Pentode

EIA Base & Outline

EIA Base: 8NEIA Bulb: 8-1
Source ........................................ GE - 1973

Application

Metal type used as rf or if amplifier in radio receivers. It features single-ended construction and interlead shields. Because of the remote-cutoff characteristic, this type is able to handle

large signal voltages without crossmodulation or modulation-distrotion and are often used in receivers with avc. Requires octal socket and may be mounted in any position.
