Do you know where to get a replacement AC power adaptor?

We have an A2 and A3 cabinet. Up until today, we had a power adaptor for the A2 cabinet. Using the model number, we found another one on eBay.

But I don't know the model number for the A3 cabinet power supply, and the older power adaptors do not work. It looks like they changed the voltage, 27V instead of 15V, based on the install guide.
