Dead 8R

Just gone to switch on my trusty Arcam Alpha 8R and it’s as dead as a doorpost. No lights, sound or the initial solenoid click as it powers up. It is bereft of life. 🙁

Swapped the power lead to check that so I’m assuming it’s the power supply? If so is it an easy swap and are they available or should I start dropping hints to Mrs W that it’s time for an upgrade?
