Gold Dragon Tubes? Still in Business?

Does anyone know if Gold Dragon tubes are still in business. I used to see ads for them in Stereophile Magazine, but no more. I bought some 12at7 Gold Dragon's for my Curcio modified Pas 3x preamp from Welborne Labs years ago, but their new catalog doesn't carry them anymore. Does anyone know where I can find info on these and other Gold Dragon tubes? Thanks, Bob D.
