        Wow, thank you Mick Bailey: I'll post pics when I get home later today. I believe they are 6V6GT white logo's. I've never heard of Shuguang before. I imagine there are other major brands that use their tubes?

          They're rebranded under Ruby, Groove Tubes, TAD and many others as well as being house-branded by quite a few manufacturers. Also sold under their own name.

            There are only three companies that make the tubes we use today: Shuguang, JJ, and Sovtek/Reflektor.

            Shuguang is a conglomeration of factories in China, JJ is in the Slovakia (I'm not sure if the name of the country is correct - my geopolitics are a bit weak since 1992), and Reflektor is in Saratov, Russia.

            But basically, that's your three choices for current-manufacture tubes...

                  Coming from the audiophool oriented end of the Industry, they claim 40 or 50 different factories while we all know there´s actually 3.

                  Least offensive is counting different Shuguang plants as if they were independent factories, worst is counting resellers and rebranders as legitimate independent Factories.

                  Economics of scale demand minimum production for any type of 50000 a year ... hard to believe that a factory´s only output is a batch of 1000 KT88 , once a year or less often, which strongly smells of 1000 unit batch , labelled with own brand.

                  Oh well.
