Hi all,

I've just re-connected my venerable Arcam Delta 290 amp to my speakers in the lounge and I'm getting a buzz coming through when I change the volume - its the same on multiple sources and the speakers are correctly connected. There are no shorts etc.

Is this a common issue on older Arcam amps ? Any idea how much to fix or am I better off looking for an eBay bargain ?

Cheers in advance

It happens whenever the volume knob is rotated...it doesn't matter if there is a source playing or connected.

Most of the time if the knob is left in place there is no crackle, but occasionally its constant...

Buzz or crackle ? If it's crackling when you turn the pot it's just a dirty pot. Get some contact cleaner, preferably with a lubricant in and spray a little in the pot. Run the pot back and forth 30 or so times then try listening again.
