lijep dar,bravo!
.
vidi na guglu kakvi rezultati bi izašli i šta se sa njima obično radi. nemam ni jednu šemu/pločicu/podatke za pojačalo sa njima mada ne sumnjam da će se lijepo upotrebiti.

možda ovako nešto?

posalo sam ti veći podatak na skajp,tamo imaš neki "remake" sa sve pločicom i ostalim potrepštinama - jedino su tamo korišteni 2SK15030/2SJ201 u TO3P kućištu. vidi da li su odgovarajuće zamjene jedan drugom i ako jesu precrtaj si pločicu u sprintu za to3,i uživaj!
