I just built the JP1 unit that Glenn mentioned (well.. a different version). my 15-1994 now operates my Sherwood 6095 with code 0491. I suggest building this unit, its the only way you will get it to work. The easiest unit I found was in the JP1 Egroups message group. (a link to it can be found in
www.hifi-remote.com) this was remote powered unit. here's the link to the pictures:

[Link: groups.yahoo.com]This unit uses about $8-$10 in radioshack parts, and only took about 1 hour to build (since i am horrible at soldering it took a bit of time). Best of luck.

P.S. Glenn, thanks again for the programming info for the Sherwood, it has made my life so much easier. =o)
