Feet for a Crown XLS1000 Drivecore power amp?

[audiomitch]

Hi all,

I just picked up one of these amps and love it so far. The thing is that I don't care to rack mount it. I'd like to put some rubber (?) feet or something to set on top of my cab. I've tried the little self adhesive rubber feet from Home Depot before (on a different, heavier amp) but they seemed to scrape off pretty easily. Any suggestions?

I'm going straight from a Tech21 VT Bass pedal in to the Crown and have no use/desire for a multispace rack case.

Thanks!
