Cats hate to walk or lie on sticky things, so put some wide tape on top of the amp, sticky side up (you can wrap in it a loop around the amp, so the sticky side never touches the amp). Use just enough so that the cat can't sit comfortably on the amp. After a while, the cats will probably come to perceive the amp as an unpleasant place, and you'll be able to remove the tape.
How do I keep my cats off my amplifier?
Since my amplifier is too large for an equipment rack, I keep it on a seperate amplifier stand. There is nothing above it to keep my two cats from climbing on top when it is turned on, which they always do, attracted by the warmth. At first I didn't mind until my Rotel RMB-1095 Amplifier shorted due to a build-up of cat hair falling inside. Now my front right channel is gone. I just bought an Integra Research RDA-7 to replace it.
Is there a good way (short of the cat pound) to keep them off?
