Substitute Data

Preferred Substitutes ......................... 4AU6
Substitutes ................................... 4BC5 4BZ6 4CB6 4CF6 4DK6 4DE6
Source ........................................ RCA RC-29 - 1975

Application

Source ........................................ RCA RC-29 - 1975
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.

Source ........................................ RCA RC-29 - 1975
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.

Electrical Data

Heater Voltage ................................ 4.2 V
Heater Current ................................ 0.45 A
