 Do not know if the power switch is faulty, it did switch the power amp off completely, no standby light was on but I could still hear the music normally. Surely with the power amp being completely switched off I should not have anything coming through the mains? I have a trigger connected between the two and this powers the amp on once the receiver is powered up. I have now tried a few times having the receiver on and switching the amp into standby and the mains are then switched off as they should be. My mains are only connected to the speaker terminals on the power amp. |
Hi,
Another thing you can try is to physically unplug the power cord of the power amp, then you KNOW it's not getting power. If that stops the sound from the mains, then it sounds like the power switch on the amp is stuck on, even when stwitched off (I've had this happen, as when you first switch the amp on, there is a huge inrush current to charge the filter capacitors in the power supply, and that current surge can sometimes weld the switch contacts together, causing it to be stuck on.)
