Thank you for this educational video. Im having problem sound, weak sound coming thru, when master volume raised to high, good and loud clear sound produce. What makes the weak sound?

Sorry for just replying to your comment. First check the power supply voltage try to fit the needs, the second check the final transistor is confirmed to be in normal condition, the third check the booster transistor and bias transistor, the fourth check the input signal enters normally, if everything is normal it is certain that the results are good.

Bagian R trimpot di setting ulang sambil ukur tegangan TR MOSFET pin source sekitar 2,8v

Jika masih serak naikkan sedikit demi sedikit dari vr trimp sampai suara serak hilang
