Unless someone else can come up with something, I'm not sure anything I know of will work. I thought maybe some digital receivers would fit, but the ones I checked- Panasonic, JVC, HK, were all 16.9" or wider, and over 17" deep. I think your depth is a problem too. The receivers with the least depth I know of are Marantz, but they're still 15 3/16"+.
