Get it out and enjoy it! Those capacitors age, whether it's used or not....We buy used Carvers to serve up our stereo AM stream to listeners, promoting the quality of AM signals when properly transmitted!
A carver, like any electronics can be likened to your "best china." You don't use the china because it may break, and you end up never enjoying it. Better to get out the Carver, USE it, ENJOY it, and let it age being used if still operable. Don't let a classic piece of equipment sit without being used. It's components are aging in the box! (Especially the caps which go bad and affect the sound.) You may as well enjoy it rather than have someone sell it at your estate sale some year!
