I've got an old Arcam Alpha 7 amp and the potentiometers (knobs to you) were wrecked early on in their lives by swmbo drying the washing in front of the multi-fuel stove in the lounge :(
I've sprayed them with switch cleaner but I should imagine that they are kaput.
Should I bin the (excellent) amp.
Send it to Arcam 4 repair.
Take it to a TV/Radio repair shop.
Or get my soldering iron out and source some new knobs from Radiospares (if they're still going) or Maplins etc.
