@Dragan83
Imaš li šemu ovog pojačala?
Čini mi se da si ovo mogao mnogo bolje da složiš pa bih probao da malo ispremeštam elemente...

@ronovar
Vidim da će ovo biti ozbiljna spravica. Smile

Za kolegu, na kraju on odustao jer smo dugo čekali da se odradi graviranje na kutiji pa ostalo meni (na moj trošak Big Grin). Šta sad? Moram ubacit mali amp unutra. Kutija je visoka 150, razmak od hladila do hladila je 100mm pa je dosta uska. A ništa, A klasa 10-ak W.

Kutija na slici izgleda dosta veća nego je u stvarnosti.

I na Draganov post još dodati još jednu taku kutiju istih dimenzija i odraditi spoljašnje, trofazno napajanje Smile

To je to. Samo si dodao drajvere i malo zaštitio FET-ove.

Skockaću lepu pločicu za ovo kad nađem malo vremena.
