I don't know where you are located, but I had Ben from High End Audio Repair in Brooklyn NY http://highendaudiorepair.com/ replace output caps that were damaged in shipping by careless UPS. He is a authorised ARC repair shop and a dog lover (so I hope he can relate). It can not hurt to at least contact him. Sometimes these shops have units and or parts from pieces that the previous owners abandoned (kind of a long shot with a 5se) but you never know.
His price was more than reasonable in my estimation and turned the job around (after a shipping delay from ARC) and I have been enjoying it ever since.
