FWIW, I contacted a person that I know who used to work for VAC (they used these tubes almost exclusively as stock in their products). This was his answer to my inquiry,
"The Chinese tubes that were labelled Golden Dragon were indeed the "pick of the litter" from the bulk tubes made by Beijing Radio. However, the factory converted to producing light bulbs exclusively about 4-5 years ago, so no more Chinese 9 pin miniature tubes. Assuming that Golden Dragon 6DJ8s continue to be sold, they may be leftover stock or they may be labelled Eastern European or Russian tubes."
