Vlauga, i think that your circuit is a good point to start, otherwise i think is necessary to start circuit with transformer on input, or need a balanced signal to drive the input devices properly.

Hi,understood the lesson because in the previous schematics transformers not work, it's my duty to post circuits that will work.
Also if i simulated its, these not are completed properly, since i not have a model of real transfomer, also i not have model parameter for other devices that i have thinking. Therefore, these circuit are presented only as an idea to start in the real applications.
Two circuits presents devices on the inputs, one with complementary pair, the other with full N devices.

This transformer thing is as old as the hills. Was used in tube radio audio stages in the 1920s using 201 (01) tubes. Was very poor, and had resonant problems with the transformers. They were 1 to 10 ratio.
