diode and leak
The optimal tapping point ( or ratio of coil inductances ) depends on the amplifying device used, which may be a bipolar junction transistor, FET, triode, or amplifier of almost any type ( non-inverting in this case, although variations of the circuit with an earthed centre-point and feedback from an inverting amplifier or the collector / drain of a transistor are also common ), but a Junction FET ( shown ) or triode is often employed as a good degree of amplitude stability ( and thus distortion reduction ) can be achieved with a simple grid leak resistor-capacitor combination in series with the gate or grid ( see the Scott circuit below ) thanks to diode conduction on signal peaks building up enough negative bias to limit amplification.
