I'm actually fairly certain the amplifier will work - the only question now is dialling in the feedback. Aside from some tweaks that are likely to arise I would tentatively call the design complete.
What remains is correcting the various layout mistakes on the boards (inevitable) and finishing the design of the casework. There may be a few little gremlins in the circuit design but I don't think there's much left hidden - the design has been extensively modelled and the previous version had proved most of the concepts already.
