    Mas Sue [kalau ndak salah juga aktif di solfegio dan aktif juga di diyaudio.com sbg kroto] kalau tda1554 ini dibandingkan dg tda8561 atau tda1552 hasilnya mana yg terbaik? Trims..

      wah, dah lama sekali ga pernah lihat blog ini… hee
      lom pernah coba yang tda8561 sih, tapi kata yang sudah pernah bandingin (orang diyaudio) tda1554 bassnya lebih terasa.
      sekarang lagi sibuk jadi jarang OL & lebih konsen ke sites.google.com/site/tinemqu dari pada wordpress ini.
      makasih dah berkunjung.

    Hi there,

    what’s the purpose of the 220 ohm resistors on the signal inputs: pins 1&2, 16-17??

      wow, its been 2 years now.
      the purpose is to minimize supply rail noise injection (if any) via PCB trace and add some low pass filter/RF supression.
      it also add some sound character with respect with resistor type (subjective).

    at full volume it required how many amperes?

      depending on the load and supply voltage, with Vs +15V and 4 Ohm load per channel (BTL), it would be roughly 7A peak or 5A rms.

      probably it is your speaker that was damaged.
