We blew out our amp this year and were planning on tossing the thing. I was looking at it and figured that it would probably be the perfect height for a monitor stand. The only real problem was that the thing weighed a ton. It was easy weight to get rid of though. Old electronics were a lot more serviceable than they are now. I took out five screws on the bottom and the whole thing slid out from the wooden case. It took about five minutes to remove all the knobs and the faceplate. Link. Flickr photos here.
