The Chinese have been infamous for dumping junk quality parts on the rest of the world. The same was true of vacuum tube production. If you wanted to see smoke from your electronics, a set of Chinese output tubes was sure to get the job done. They were even worse than the Russian consumer crap.
Once perestroika took effect, Russian tube manufacturers were forced to look for other clients, outside of their military. Turns out that Russian military tubes were very well built. Many of their tubes are interchangeable, or very close to European/American tubes. They have pretty much been the go-to guys for quality new production.
Someone finally convinced the Chinese to try making and selling a high quality line of tubes. they hired the right people from England, locally and elsewhere and now there are superb Chinese tubes to be had.
Psvane, Treasure, Genalex Golden Dragon are a few examples. They are not cheap, but they are high quality.
Bottom line is that the Chinese CAN make high quality parts for our consumption. Trick is finding the correct sources. Speedmaster has evidently done just that. I wish them well!
