Mene jo rectifier banaya 25v 4700muf se 12 -0 -12, 3 amp transformer se, wo multimeter me 18volt DC kyu bata raha hai hai, kya ye board 18v se bhi chalega ?
Apne 25 volt capacitor lagaya hai isliye jada volt dekh raha hai... par wo open circuit me jada dikhata hai... ap jab use board se connect karenge to volt ghat jayega... no problem..

Ajkal jo 12 Volt transformer mil raha hai woh 14 volt Ac output deta hai jo filtering ke baad 19-20 volt peak output deta hai par amplifier board lagane ke baad 19 volt ho jata hai aur amplifier jab maximum sound deta hai tab around 16 volt ho jata hai. Tda7297 ke datasheet mein maximum voltage 20 v hai matlab transformer maximum voltage hi de raha hai
