Alam ko bro. kaya nga kailangan natin gumamit ng Automatic Voltage Regulator, just because the voltage
coming from Meralco ay pabago bago.
Very true. In the US you won't even see AVR's sold in the big electronics shops like Fry's. A line conditioner is all that is needed if you are anal about your precious gears. Line voltage is a solid 110V in our area (Nevada). None of our appliances are plugged in an AVR.
Sabagay if the local power company there manages to make a mistake a burns out the gears of any consumer they will face lawsuits left and right in which case they WILL lose.
Here....good luck in filing a case vs Meralco if you blame them from frying your amp, TV or anything because of over voltage.
