Ezekial had a great sugestion, the Sylvania WGT's. They work pretty good. But, the metal base W's, and the Tungsol round plate black glass are the reigning champs in the Supratek camp. Also the short bottle brown base Sylvania W's. I'm sure you would get the same results in the Rouge.
I imagine these should sound pretty good too, for what they cost. One other brand that I really like but can never find are Toshiba's. I haven't compared the plate structure to others, but they are a GTB with a chrome top. I was extremely surprised at how good they sound and also are as close to noiseless as you can get.
I only use the tube dampers on my phono tubes, but I imagine they should help also.
