baka nafry lang yung IC niyan or what.. ganun nangyari dati sa isa kong amp.. akala ko nga fuse lang apektado eh.. pero yung fuse niya got damaged as well as the IC..

pinagawa ko lang sa isang electronics store dito, buti meron sila nung IC na kagaya nung sa amp.. ayun.. total damage ko for repair was 300 petot..

patingnan mo muna, baka ganun lang din nangyari jan..

umiilaw pag naka-on pero wala talagang sound?
kasi pag fuse blown yan, hindi yan magpopower..

baka naman naka zero lang ang volume or sablay ang saksak ng cable.. common mistake ng iba yun eh..  :lol:

Patingin mo na yan sa repair shop kasi 1st do you have the right tools and knowledge to test the amp.Malamang open na Amp IC mo kasi nagoverheat try mo 40watts alam ko kasi 50% lang volume pwede mo gamitin dyan kasi solid state yan.Ganun kasi lagi setup ko sa vol 50% max ko na yun para di magoverheat yung Amp IC.Mura lang yan less than P50 lang yan IC.Meron nyan sa Raon.Kaso layo mo pamasahe pa lang luge na

kadalasan eh IC's yan..either the preamp or gain stage..mura lang yan sa electronics shop..kadalasan dual opamp ang ic niyan, like RC4558 or JRC4558.. you can replace them with the same IC or pwede ring TL072..mas ok for me yun..

suggestion ko po next time na buy a higher watt amplifier para hindi mabilis masira 8-)
dahil kapag max mo yung volume may tendency masira yan talaga
also i think a lot of music stores fix those type of problem.
Nangyari na ito saakin napaaus ko naman sa lyrics trinoma
pag balik saakin good as new ang tunog

check mo yung impedance (ohm) ng speaker.. if you don't know what impedance to get, kung ano nalang yung impedance ng stock speaker, dapat ganun din ang ipalit mo, to be on the safe side.. check mo rin yung wattage nung speaker, dapat 15 watts or higher..
