Crapapples: which DC socket?

[bobbletrox]

I bought a DC socket from DSE today, but I'm not sure if it's the right one for pedal powerin'.  

The one I bought is a 2.5mm, but I just realised they also sell 2.1mm sockets.  They were all jumbled into each other's boxes when I was at the store so I didn't realise there were 2 kinds!  Do I need to haul my butt all the way back to the store to see if they stock the 2.1mm socket?

Also, do boss adapters have the + in the center or the - ?  

Danke

Boss is 2.1mm with centre negative.
Crapapples indeed.... I've been there!

Thanks Paul!  I hope they've got the 2.1mm in stock...because anything's possible with DSE.  The sockets are just like the one's I've seen other people use, except they've got a plastic nut instead of metal.

Where are you situated, Bobbletrox? jaycar is usually a better bet.

I'm in Brisbane, and there's a Jaycar nearby...but they only seem to have metal, and rectangular plastic DC jacks.  Although, I drill my boxes before they're powdercoated, so I wonder if the powdercoated holes would isolate a metal DC jack?

I wouldn't chance it.  A small chip when you do the nut up could create a short to your case.  

Whenever I shop at Jaycar and see those metal DC sockets I wonder why anybody would buy them?  I also wonder why Jaycar's buyers haven't thought of stocking the insulated type?
