I got some cheap things from currys of all places, although of course I couldn't get proper hifi stuff to do the huge extension to the turntable lead to feed into the nest!
Still, I learned what an F plug is and the WiFi seems to have back to life as well as the tv. Hurrah. Think I'd like some virgin sponsored kit later though as wot I got seems well flimsy compared to what I had.
Thanks.
