H431 mergea minunat, rapid si precis. Mi s-a ars iesirea la unul , prin anii '80, si l-am desfacut din silicon. Era facut cu integrate banale (741, 555, etc.) si cu componente discrete la fel. I-am inlocuit BC-ul ars si i-am scos schema pentru a-l reproduce. Au mers bine si reproducerile, dar am pierdut schema. Poate o are cineva.
