I left a post on the forum here, in the manufacturers section under Kessil.
I did manage to find a used one on ebay right after I posted my message. Got lucky.
But I'd really like a new back up as all I run are these a360s.
I'll give them a ring tomorrow as well.
The power brick is not unique and as result there are alternative available. I lost one over year and half ago and purchased this as a replacement and has worked. Unfortunately it's not currently available. The key is matching the barrel and volts/watts.
