Daca vrei alimentare asimetrica(simpla 0-40V) la amplif, poate sa fie si 50V, atunci poti sa folosesti o infasurare, o sa ai in jur de 45-48V in sarcina depinde de filtraj, daca vrei alimentare simetrica +-25V folosesti tot o infasurare 0-20 pentru o parte si 20-40 la celalalt, cu o singura punte, si filtraj pentru fiecare "canal".Pentru 40W este deajuns +-25V(sau 50V) si cu dif. de 8 ohmi.
