Chuck Phillips, the MacCaps guy above is a diagnostics and repair resource for Apple (from the Apple II up to current Macs) and it seems NeXT computers. His recapping covers all vintage motherboards and will do an A4000D for $55 and an A3640 for $20 (plus shipping); his current turn around time is about a day shipping to and from Southfield Michigan. He would do Amiga repairs if he had one to work with and I sent him the plugs to make an A4000D and A500/600/1200 PSU harness along with a bootable IDE HDD. With some help from the Amiga community, he may be an North American resource at reasonable prices ($36/hr) and quick turn around. I have an A4000D motherboard in the mail to him at this moment.
