Hey AB

Are what you want to replace 2 amp or 1 amp mate? I've got a drawer full of 12v wall warts and other psus from old modems, hard drives, IT equipment etc. I can send 4 or 5 to you if you like (they will just go to the ewaste bloke otherwise)

More often than not the tip/barrell size is the same so it's just the amperage requirement that changes. If you're keen for some freebies, just send me a photo of the existing tip or its measurements.

Having said that, I've dremelled one that wouldn't fit for me with no negative outcomes - it's only removing plastic on the side and there is no exposed circuitry. Those little 12v/2amps don't get anywhere near hot enough to need large air gaps in my opinion and I see them all the time in my industry.
