I second the option to get the replacement from Vincent if only for practical purposes. However, and not contradicting... I never use mine, as my commands are programmed into my Philips Pronto 7500 and Marantz 9500 universals. This for me is more convenient and may be a simpler/cheaper option in your case. My SV-236 is in an equipment closet powering speakers in a second floor/zone location. Funny thing, the direct commands for volume did not program well but I was easily able to find them on Remotecentral.com
Now I'm looking into upgrading the tubes. Good luck!
