the voltage is correct. if not, the avr is blown the minute it is plugged. my situation is, it rarely sparks. ive been using it for a month and today is the second time it happened. when it sparks, there is a red light blipping. i turned off the receiver and when i turned it back on, everything seems fine. the receiver works fine and i cant find any problem with it.
i really dont have a clue why it happened.
