Tak kuszą te schematy, osobiście to najbardziej jbl'a :D. Trzeba by się poradzić RoMana na czym by można zrobić te dławiki, może na jakichś dużych ferrytach proszkowych ... Wygrzebałem konstrukcje jbl'a Full-bridge ir2111 i ukochane IRFP250. Moc tylko 300W (500W peak) niestety pcb nie udało się znaleźć
