Hi,
I am trying to get my Cambridge Audio A3i amp working for this weekend for a party. The speaker protection circuit will not kick in. I know about the problems with the LED's and current sources etc, not any of that, all been replaced. There is only a few millivolts of DC offset, the bias is correct nothing overheats but the relay will not close. I think the problem lies in the protection circuit itself. Does anyone know what this might be or have the schematic covering this part of the circuit they could e-mail me?
