A strange thing happened to me yesterday and I can't explain it..

[Lawrence001]

I was reaching down to switch off my system at the mains block and I heard a click from the rack that sounded like a relay. Each time my arm went near the block or away from it, there was a click. I positioned myself between the block and the rack to check it was.coming from there and it was. I moved my arm back and forth at different time intervals to make sure it wasn't a cooling noise and the clicks always coincided. Unfortunately when I moved close enough to the rack to try and work out which compenent was making the noise the angle of my arm no longer caused the clicks. When I moved back it started again. But after 30 seconds it stopped completely. Bizarrely half my components were on and half off but the only things I knew that had loud relays were my 2 amps which were switched off. The only out of the ordinary thing was a very bright sunbeam shining on the rack. So what was happening here any ideas?

You have a clicky arm!

[struth]

Yeah, maybe a ligament or gas in a joint. Can even get it in your ear. If not then hard to think what else it is unless you were actually touching something as you moved. Bad power connection etc

Cant be that it was my arm to the right and the clicks were coming from the rack on the left,a distinctive relay click exactly matching the movement of my arm. I meant to say my arm blocked the sunbeam as I moved it so was wondering if there were any opto electrical switches or relays in some gear.

Have you got an amp with a remote control mute function, or similar?

Heat on casing causing a rapid expansion then contraction as you block the sun?

I'm clutching at straws here.

Yes but it was switched off!

But it sounded just like the mute on it.

As I found it so weird I did the movement 30-40 times to investigate the direction it was coming from and make sure it wasn't my imagination or something else.
