That's Ok Tom, I just appreciate you looking out for me. As it seems functional right now I'm content to just listen to the Beeb
It was obviously well loved and not at all abused, except for the curious burn mark on the grille cloth. Not even a dead varmint inside either - very rare to find a tube unit in Bermuda that hasn't become the tomb of the unknown cockroach.
It has now taken pride of place in my shelving unit, perfectly positioned within knob-twiddling reach.
Cheers
