Question about Cambridge Audio Azur 640A Amplifier
Often when turning the amp on, the sound from the right channel does not come through at all, but not always (i.e. sometimes the channel is fine when turning on). Switching between input sources usually solves this, sometimes just by switching once and then back, but mostly needing to switch multiple times back and forth before the sound comes through. It doesn't seem to matter which inputs you switch back and forth to get the sound back and also doesn't seem to matter if there are any active inputs on the input sources being switched to and back from.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.
