Not sure if I've posted this on the right forum, apologies if I haven't. After many years of faultless use my trusty Roksan Kandy KA1 mk3 integrated amplifier. It has suddenly started, and continues to, constantly switch itself to standby mode. When I try to bring it out of this, it does so for a few seconds before putting itself back into standby. I have tried a number of different power leads, and have disconnected it but to no avail. This is afar as my technical skills stretch!! Has anyone come across this or is able to shed any light? Cheers.
