My ears are bleeding
I may have to check the rivets on my AR3a speakers. I didn't detect any issues, but once open, may as well check to play it safe. Definitely some of the easier pots to service, though not necessarily the easiest to get at or remove (hate having to De-solder stuff, time consuming).Stay off the pot! Drugs are bad! M'Kay
Maybe somebody's has bypassed the pot and removed it, or it a earlier version. Can you see the hole wher the pot was? Post some pics. My Ar4x's had bad solder joints at the tweeters and one also needed the rivet on the connection terminal on the tweeter soldered to make a connection.
