(under subclass 152) Subject matter wherein at least one of the interstage coupling means has a cathode follower signal output.
(1) Note. If only the coupling of the last stage is a cathode follower and none of the previous stages has a cathode follower output, classification is not in this subclass. For classification of cathode follower amplifiers and analogous subject matter see search notes immediately following.
SEE OR SEARCH THIS CLASS, SUBCLASS:
119, for push-pull vacuum tube amplifiers including cathode followers.
168, and 172+, for amplifiers having a cathode follower in the interstage coupling.
193+, for amplifiers with cathode follower output coupling.
310+, for cascaded semiconductor amplifiers which may have an emitter follower stage analogous to cathode follower in a cascaded vacuum tube amplifier.
