Thanks for the suggestions everyone. George I did ask my son to listen too, coz I certainly have done quite a bit of Led Zep high volume listening over the years! He thought there was a slight treble enhancement when the treble control was turned right up, but I think he was talking himself into it. And when I blind-tested him he was really struggling to convince me. Anyway, I sprayed out the switches and all the potentiometers with Servisol 10 and gave them a decent work-out. Sadly, this has made no difference. So I'm still stuck.
