Hi TJS
Not all Meridian Gear - seems to have more issues with the Switched Mode Supply gear.

I have never suffered any major power supply issues with my 500 series equipment - except a blown mini fuse which did not blow a second time - and am pretty sure they all use Linear Power Supply architectures.
