I have the same problem. The plastic casing around the power jack cracked and now it does not make a good connection, resulting in much noise. Please let me know if you can find where to get a replacement jack.

I’m not sure if the POG2 is 2.5mm or 2.1mm but here’s each one:

I think the center negative EHX stuff (like POG2) is 2.5mm & the center positive stuff is 2.1mm.

I’d urge you to be careful, I’m willing to bet you could damage your pedal if you do the plug wrong. Probably why tech support probably urged you just to buy a new power supply.

honestly, I’d recommend getting a Voodoo Labs Pedal Power 2+. They’re expensive (about the cost of a pedal) but a really good investment, & if one of your plugs break, you only have to replace a cable that costs a couple bucks instead of a 10 dollar wall wart.

I used to use a Onespot & a 3 or 4 wall warts on a strip, but the PP2+ got me down to it + one wallwart (40v for my frequency analyzer.) It also got rid of all my noise that my pedals were making, because I was able to isolate their power from one another.
