    Try to heat up the amplifier with a heating gun and check if it fails. Do not heat it up to much with the heating gun!! 135-140 dgr F (55-60 dgr C) is enough.

    What is the brand of the new power pack for 43 dollar!! Check if it is a Chines manufacturer. In my opinion keep away from Chines aftermarket parts. It is crap, buy a OEM, Sierra or CDI part and you will not be disappointed.
