Evo sheme nacrtane u Eagle-u. Nisam ubacio prekostrujnu zaštitu jer kod mene pojačala rade uvek ispod 1W snage i nema nikakve šanse da pregore. Zaštite stavljam više zbog turn-on i turn-off mutinga. Onaj ko pravi pojačala za koncertna ozvučenja može lako da doda na shemu potrebne komponente preko rezervisanih 1N4148 dioda i da napravi svoju pločicu. Ja sam predvideo dva 12V/15A releja kojima su kalemovi vezani redno zato što takve releje imam na lageru ali svako ko koristi Eagle može lako da prepravi shemu za njegove releje.

Preračunao sam LP filter za manju kapacitivnost (1u) i smanjio vrednost bleeder otpora za LP filter. Koristio sam Okawa online calculator. Male sive ćelije! Hercule Poirot!

Ako neko primeti grešku na shemi neka prijavi pre nego što postujem Eagle sch file.
