Does anyone have a schematic of a "butler" amplifier?
Google turns up alot of audio buffs talking about it but I have yet to see one. Apparently, it is (was) popular is some audio amplifiers as a low noise, high linearity front end input stage. It utilizes JFETS & bipolar's
It's called "butler" due to it's inventor?? Also used in some low noise opamps like OP275.
Does anyone have a schematic for one? I'd like to see it.
Thanks
