Yup, ordered some parts couple weeks ago and received the invoice to pay yesterday. The site is up and working. I think Joe is often extremely busy, just be patient. It is amazing the amount of detail he puts into his kits. All components are separately bagged/tagged and leads are pre bent perfectly. Can't see how he does it all by himself, must have magic elves.
An ultra reliable 400 would use the 700 chassis and heatsinks with the bolt pattern of a 400 transformer. 10 outputs per channel = lower dissipation by each one. It would be hard to blow that one.
