Reflex circuit ensures full use of available gain of two-stage relay control ampliler using 12AT7 twin-triode. Tube V2 controls relay in its plate circuit and also serves as a-c amplifier, increasing over-all sensitivity by factor approximately equal to a-c gain. Performs best about 400 cps.-Sensitive Relay Control Amplifier, Electronic Circuit Design Handbook, Mactier Pub. Corp.,N.Y.,p103.
