12В ЭПРА для люминесцентных ламп мощность до 20Вт, проверка с ЛБ 8-3
Транзисторы немного греются, примерно до 60...70 градусов. Так что радиатор все же нужен. Потребляемый ток составил 1,12А (источник выдает почти 13В, насколько помню). В процессе настройки и исследования схемы было пробито два IRF540Z, два танталовых конденсатора 2,2мкФ 25В и два 3А предохранителя.
