    Bos IC LA 78XXXX hanya perlu VCC 8V, jadi kalo dr 12 V nya dah Droop mungkin Perlu di cek suuply 12 V nya. ( Coba Cut Dulu VCC IC LA 78XXXX trus Cek Tegangan Peak to Peak bagus ga ? )
    Intinya :
    - kemungkinan masalah dr input PS 12 V nya, sebab IC LA & 78XXX jarang ada yang short dari VCC,
    - Pengalaman saya ( ganti Capasitor dan Dioda + IC 78 12 nya )

    Smoga sukses.
