These are a good source for anything exotic or old. Since you're in Framingham, I recommend the Heavy Hitter's Hamfest at the Topsfield fair grounds July 24-26. You'll need the usual tube voltages. As I recall, they are triodes, with the plate current (controlled by the grid voltage) controlling the amount of "wink" (or whatever you call it). I've got some schematics at home and can probably get pin-outs and voltages if you can't figure it out.
