My buddy has a Quadzilla chip on his 02. The power level switch broke leaving it stuck on the highest setting. I heard Quadzilla went out of business does anyone know where I can purchase a new switch? Did another company take them over? He kept the box and here is the numbers Quaidzilla D02XZT 30272
Any help is appreciated.

 

Try taking it to an electronics repair shop such as Altex Electronics or possibly one that repairs stereos.
