Drawing Request

It would be amazing to have an actual drawing of a totem-pole schematic here :)

Be amazed. Dicklyon (talk) 22:22, 14 April 2011 (UTC)[reply]

Too bad it's not illustrating a push-pull output. I don't know what it's illustrating. PNP and NPN transistors? Collector of one hooked to the emitter of the other? It'd be nice to acknowledge the bias problem, as well. An incorrect picture is worse than no picture. --Wtshymanski (talk) 13:20, 14 September 2011 (UTC)[reply]

Better picture found, showing + and - power supplies and load, also a tube-type amp schematic with center-tapped transformer. --Wtshymanski (talk) 15:32, 14 September 2011 (UTC)[reply]

Expansion

As usual, no history - push-pull amplifiers are designed with out comment in the 1945 Radiotron handbook, so doubtless the technique is nearly as old as vacuum tubes. I've tried to put in some explanation as to *why* you would want these various perversions in a circuit, but I can't find any history yet. --Wtshymanski (talk) 21:43, 29 November 2012 (UTC)[reply]
