Default Re: Matched Transistors

I believe it depends on the output p-p circuit, whether the match is important or not. Complementary circuits where the output devices are used as emitter followers don't worry too much about matching but the transformer driven transformer output configuration is more fussy about reasonable matching.

Not sure where the transformer driven totem pole types fall.
