(ge. 6AU6-A—3AU6—12AU6 3AU6 \\ J) 12AU6 p ET-T916A Electiant® PENTODE Page 1 4-60 TUBES sss DESCRIPTION AND RATING =" The 6AU6-A is a miniature sharp-cutoff pentode primarily designed for use as a high-gain radio-frequency or intermediate-frequency amplifier. Its low grid-plate capacitance and high transconductance make it especially suited for high-frequency wide-band applications. Except for heater ratings, the 3AU6 and 12AU6 are identical to the 6AU6-A.

These values are chosen by the tube manufacturer to provide acceptable service- ‘| ability of the tube, taking responsibility for the effects of changes in operating y conditions due to variations in the characteristics of the tube under consideration. .
