88+, and 91, for cascaded amplifiers having signal feedback to the cathode.
117, for amplifiers having unbalanced-to-balanced coupling including phase splitters with cathode coupled output.
119, for push-pull amplifier involving coupling from the cathode. 153, for different interstage coupling in cascaded amplifiers including a cathode follower stage.
156, for bootstrap coupled amplifiers.
172+, for interstage coupling from the cathode for other than transformer coupling.
