    Pioneer Sa 7800 power transistors burned out

    Hi everybody, yesterday, while my sa 7800 was playing some music, the protection went off and I saw a little smoke coming out... Upon inspection, the two power transistors of the right channel resulted shorted, three resistors seem a bit scorched and the driver transistors are dead as well...
