I am pretty sure they are made in China .. Pretty decent tubes,,,but not better than any other cheapo new manufactured tube...I have used the 12at7 G.Dragon for years and it a decent tube but can't say its great...They are cheaper cost wise do to the low cost of labor in China...Should be the same company....

Has anyone tried the current Golden Dragon Kt-88, 300b or other GD power tubes? They are sold in England, are they the same as the old GD tubes from 10 years ago?
