Notes

Characteristics of the triode sections are close to those of the 12AT7; the diode sections are similar to the 6AL5.
The two triode sections are symmetrical and independent (separate cathodes), as are the two diode sections.
Designed for FM stereo multiplex circuits — linearity was not a primary design goal, so performance may be limited in applications requiring large voltage swings.
