Just in case any of you have got some of the old Bye Bye Standby BBSB4AW sockets, and they have the standard failure mode - turns on, then immediately turns off again - take a look at BigCliveDotCom's "Fascinating failure mode of metallised film capacitors" video on Youtube.
Just in case you don't want to watch the whole video, you need to replace the large yellow 220nF capacitor !
I will sort through my old sockets to find a failed one, and replace the capacitor to see if that sorts it out. If anybody else is interested, I have just purchased 50 capacitors, so there will be some left over ! Just in time ! I was about to dump them !
