How to remove the front panel on a Harman Kardon 330B

I just bought a Harman kardon 330B at a thrift store and it works great, but it looks like the power button took a pretty hard hit. I'd like to see if I can straighten it out, but am having a hard time figuring out how to remove the front panel so I can get to it. Has anyone taken one off? Any hints on how to do it?

Thanks, Mike
