I Have a problem with this Mixer. Sometimes when i'm using it, it starts to turn on and off too fast... I'm not shire if it is a problem with the transformer inside, or a problem about one peak when one friend of mine put one Jack inside it and that jack was broken... I don't want to loose that mixer because it is the only one that i have and i don't want to buy another one. Thank You
