Hi, darling! I slightly corrected your circuit so that Q1 would not fly out, put R1

thank u so so much for correcting the circuit. But i still have the question about how to set the number of rbe.

My teacher says if u set rbe of 3 BJT as the picture down there goes, there should be a perfect wave of Trigonometric Functions(sry for my poor english)

Поскольку анимированные транзисторы создают плохую сходимость, меняем их на другие модели. Снимаем ограничения синусоиды путём установки в схему дополнительных резисторов

и проверяем, не нарушены-ли режимы транзисторов по мощности:
