[QUOTE="Steerpike, post: 892667, member: 807"] It is practically* impossible to build an amplifier that uses NO negative feedback. You can omit global feedback, but there will always need to be several stages of local negative feedback. Almost all commercial amplifiers use a combination of these two types of feedback. * I mean practically in it's true sense, not meaning 'to a large extent'. My Philips AG9014 from 1958:[b] frequentiebereik 7 Hz tot 50 kHz, 0,5 dB[/b] HALF a dB ! not -3dB. [/QUOTE]
