*Golden Dragon are very good tubes. Some selected power tubes are probably the best value among current production, IMHO. I have used with great success the double plate 2A3 (not the current version). About 8000 hours service without any issue and perfectly efficient. It also has gold plated grid to minimize grid current. I don't know about signal tubes though as NOS types are still in abundance....
Several of those tubes are made with original British tools by GEC or similar under strict British specifications . It's really true. The KT66 in particular is really beautifully made thing using quality materials so much that buying originals at stellar prices is just silly, unless one wants them for his collection.
Also Valve Art sells this and I think the origin is the same.....
Back in the late nineties, for a few years, they used to make a special version of the 300B. It featured a titanium plate and was called 4-300BLX that they copied from a Japanese re-make, I think, before WE decided to come back in business. Nice stuff!

*中國的 Golden Dragon KT66非常接近GEC,是GEC的忠實副本
棕色玻璃底座是優秀的閥門，非常接近原件，尤其是 Golden Dragon透明玻璃版本....................。
