Today, I drill some acrylic and heatsink to mount the regulator PCB. What a tiring drilling job! Not too easy to drill a lot of holes on the heatsink, though (not included the wrong holes one!).

Finally, the PCB could be mounted beautifully. The pass transistor mounted on the separate heatsink on the bottom. I just need to wire them to the PCB, add the main transformer, then we can evaluate its performance.

    itu diodanya berapa ampere (IFnya) dan resistornya berapa watt ?

    Ya secukupnya kamu mau pake aja bro kalo dioda mah.

    Resistor 1/2W cukup koq, kecuali yang buat jengkolnya kasih 5W.

    Thanks.

    salam,
    saya ada toroid made in usa 2x36v 500va, mau dipakai untuk power amp with +/-25v rails, so daripada mubazir terpaksa saya regulasikan saja, kira2 apa ada rangkaian regulator terbaik untuk menghandle 500va current?
    dan apakah pengaruh ke suara akan lebih baik atau buruk?

    trims.
