para malaman mo kung naka protect ang unit
pakinggan mo kung mag ciclick ang speaker relay
after powering on.
It will take a few seconds then saka pipitik ang relay
if not, then naka protect ka nga
kung sira ang ic mo like there is a dc offset
then mag poprotect ka talaga.
pero kung wala kang dc offset
tapos nde pa din nag ciclick ang relay mo
then possible may sira ka din sa protection.

tapos itong dalawang resistor, 100 ohms value pero pag sinukat ko 160 ohms na sa actual, hindi kaya sira na ito?

kung change value na yung resistor then replace it na din

it should be +/- tolerance % (assuming na metal film yung resistor na yan at 5% tolerance) hindi aabot ng 160 ohms. so yeah kung maari palitan yang resistor na yan.




inboard test mo ba yan?? o tinangal mo sa board?

normally pag nag sukat ka sa speaker terminal
dapat wala kang ma measure na dc
pag meron iyan ang tinatawag na dc offset in laymans term
dapat 0v or 10 mv depende sa design
