Enjoying my i20 but recently the power supply has been making weird noises. The noise is a like a super high pitched hum which happens totally independent of the dock. Once I unplug the wall wort it goes away. I'm thinking I need to replace it. Since I'm in the market I thought I'd ask around here. Any suggestions? Radio shak? Teradek? I'm open to suggestions. 
 
P.s I emailed pure three times no response.

Nobody has any thoughts? I'm a total electricity neophyte. I don't want to just plug something in only to have it ruin the doc.

So i know the i20 uses a power supply rated:
 
7.5v 
1.2a
effiency level V
input 100-240v 50-60 Hz 0, 4A
 
Do i want linear or switching? I have a switching but its making noise. It wasnt before. Anyway i've looked around and understand i need to know more about what i need before i can actually look for what i need.
