Good people,
got a harmon kardon amplifier, which has been sitting gathering dust for the last couple of years, when I use it (which isn't that often) I get a load of crackle and static, through the music when I turn up the volume, which continues for as long as I use it.
Any hints and tips on how to clean it, remove dust, make it sound like its brand new, friend wants to use it for a housewarming, and I'd like to get it back into tip top shape for them.
Many thanks in advance...
