My thoughts entirely, surely both amps wouldn't have the same fault and even if there was a problem they should light up red or yellow if there was a problem.
Over the weekend I swaped them for my Beolab 8000, which will be my front speakers and they work, so I can assume the powerlink cables are ok and there is power, trouble is the Pentas are such big beasts to take to the shop, unless I dismantle the amps off of the bottom - and that will cost an arm and a leg.
ho hum, whatever at least I will have a decent set of speakers at the end of it.
Any other ideas - are there fuses inside the grey bit?
