Remote-Cutoff Pentode

EIA Base & Outline

EIA Base: 7BKEIA Bulb: 5-2
Source ........................................ RCA DS 8/59

Application

Miniature type used as rf amplifier in standard broadcast and FM receivers, as well as in wide-band, high-frequency applications. This type is similar in performance to metal type 6SG7.

The low value of grid-plate capacitance minimizes regenerative effects, while the high transconductance makes possible high signal-t-noise ratio. Requires miniature 7-contact socket and may be mounted in any position.
