You shouldn't run amcheck as root, but it should be suid'ed,
and owned by root.

        $ ls -l /usr/sbin/amcheck
        -rwsr-x---  1 root disk 89212 Apr 22  2005 /usr/sbin/amcheck

To change the device, first note what device it is, say /dev/sg99, and
your tapedrive perhaps /dev/st88 and /dev/nst88.

Then logged in as user amanda (or "su - amanda"), the dash is important,
determine the group identity of the amanda user, perhaps:

        $ id
        uid=33(amanda) gid=6(disk) groups=6(disk)

So group 'disk' in this example.  Now make the changes to the device.
As root do:

        # chgrp disk /dev/sg99 dev/st88 /dev/nst88
        # chmod 660  /dev/sg99 dev/st88 /dev/nst88
