I am a silly *********! The primary of the mains transformer was open circuit, probably due to a failed thermal fuse somewhere in the winding. Borrowing a similar, but larger transformer from a different DENON model proved that the various functions all work, and there is good quality sound from the CD player, though, for a reason I haven't yet established, no sound at all from the radio. I've been told by someone at Charles Hyde that the mains tranny is no longer available, so either a suitable substitute will have to be found, or the set is scrap. What I don't understand is why the lack of the main and supplementary DC supplies due to an o/c primary, should cause protection circuits to trip, and the standby/on LED to flash.
