Description
ДВУХВАТТНЫЙ транзисторный усилитель МОЩНОСТИ ЗЧ
Сырая!
Налаживание. Предварительно установить R7 в среднее положение. Проверить напряжение на эмиттерах VT3 и VT4. Подбором сопротивления R6 установить в этой точке напряжение равное половине напряжения питания, то есть, 6V (при питании 12V).
Подстройкой R7 установить минимальный потребляемый ток покоя при минимальных искажениях.
