I'm writing this in the hope someone has had a similar experience and can offer some advice. I've got a set of KEF Eggs and sub woofer connected up to a Sony amplifier, but recently the sub has started humming (so it hasn't always done this), but it doesn't always hum from the outset. Observations I've made are as follows :
- test tone performed via the amp indicates sub is working
- if I leave the sun on but disconnect it from the Amp the humming stops
- switching off the amp doesn't stop the hum if it has started (though it does eventually stop after a period of time
- Amp, TV, sub, ps4, sonos etc are all plugged in to a power surge protected extension block. Unplugging the sun from it and connecting to a its own socket in the wall doesn't change the symptoms
I don't have a way of testing the sub independently in the Amp so can't determine if the fault is with the sub or amp.
Any thoughts or suggestions welcome. Thanks, Simon
