Question about Cambridge Audio Azur 540A Amplifier
Get hold of a Servisol freezer spray, from either Maplin or Radio Shack, depending where you live. Take the top off and look inside. Locate the output transitors for the right channel and with it powered up wait for the fault to go away. Then with the spray, squirt any of the transistors you suspect. If it starts up (the fault) after the spray, that part has gone!
Do them one at a time and wait a while before spraying the next part. If you find one that acts up, to make certain, warm it back up by touching it with a soldering iron. Then freeze again.
