Remote Control for Nakamichi RE-2

I'm looking for the remote that came with this unit. Barring that,does anyone know which model of remote will, in the very least, let me adjust volume control on this receiver?
It's possible that a remote for an AV-300 or AV-500 would work. I know that the remote for my AV-300 worked just fine on my AV-500 but they are more closely related.
