I have, at last, got around to dismantling and checking this radio. Everything seems to be working perfectly in as much as the radio can be powered both from internal batteries (4 x 'C' cells) or it's outboard 'wall-wart' PSU, and all wavebands & functions are working. It seems that the problem mentioned in my first post (display blank, but audio amp. on) is to do with the 'standby' circuit fitted to the R827 and isn't really a fault at all. If it's still available, I'll download the User Instruction manual, which should explain things!
