Some months ago I "inherited" from my father a setup consisting of Quad 303, 33 & FM3, a Garrard 401 & SME 3009 and a pair of Quad ESL 57s. They have spent the intervening time up in the loft. A few days ago I brought them down and wired up the Quad items. I set them up with a CD player which I also inherited and have been listening to them.
Out of interest I turned up the amplifier today and noticed that on one of the speakers there were small, faint flashes (¿sparks?) on what I believe is the middle panel.
Can anyone tell me what the significance of these is and whether they will do or they indicate damage?
For what it is worth, the setup and the speakers sound absolutely wonderful - sadly, my wife is not entirely happy about having such huge speakers in the living room - but I will work on that.
