Opamp with Class B output stage distortion. I am just trying to understand what is going on in my very simple amplifier. I am following a post on the internet. So I got to the first schematic and i added a buffer at the input. And measuring the output with my oscilloscope gave me a nice output with no load.
EL34 simple push pull class B : why 100W ? | diyAudio
https://www.diyaudio.com/community/threads/el34-simple-push-pull-class-b-why-100w.146654/
Very approximately, Class A offers about 25% efficiency and typical Class AB about 40-50%. The highest efficiency you're likely to get from Class B is about 68%. That means that for 100w output the total power input will be 100w x (100 / 68) = 147w. This means that the tubes themselves will dissipate 47w between them, or 23.5w per tube.

Class B Power Amplifier - Tutorialspoint
https://www.tutorialspoint.com/amplifiers/class_b_power_amplifier.htm
The circuit of a push-pull class B power amplifier consists of two identical transistors T 1 and T 2 whose bases are connected to the secondary of the center-tapped input transformer T r1. The emitters are shorted and the collectors are given the V CC supply through the primary of the output transformer T r2.

Noir Headphone Amplifier – diyAudio Store
https://diyaudiostore.com/products/noir-headphone-amplifier
Noir exploits the well known advantages of class-A operation and a minimalist all-discrete circuit design. The amplifier consists of only two transistors (each operated in single ended class-A) giving a very short and linear signal path. There is a 1/4" headphone jack on the front panel, and preamp outputs (RCA jacks) on the rear panel.
