Not that kind of hum.
It's been happening for some years now and I suppose I ought to get new speakers. The strange thing is, if I tap the woofer, the hum goes away temporarily. Then, v-e-r-y slowly, it starts to come back, sometimes taking 20 minutes to get up to full pelt.
I've done a bit of research (Googling) and I've read about ground loop hum, but wouldn't it just hum all the time regardless of whether I've given it a good hiding?
I've disconnected the other speakers, put the volume down and made sure the woofer is away from other cables and interference, but it still does the same thing.
Any ideas? Cheers.
