Where may I find a replacement power adapter for my 30" Cinema Display?
I have a 30" Cinema display and have lost the power supply for in process of moving and would like to find a replacement adapter.
I suspect your model is obsolete if it is the 30" model, double check that it is. Vintage and obsolete products - Apple Support
Contact an Apple store & see if they have any in stock or can source one for you. Otherwise search Amazon/ Ebay & the rest of the internet.
A final option is to build one yourself from a suitably rated LED power supply assuming you are able to handle high voltage electronics (or find someone who can)…
