Krell remote substitutes


I have an older HTS 5.1 I bought a while ago that didnt come with a remote. Pulled it off the shelf last night and hooked it up and realized it is useless without the remote to set it up with. I have PLENTY of universal remotes around the house. If you have kids you understand. Need help either with codes to try or a remote that will work with it. Thanks.
