The fire was August 2019. The Changsha city government will not let the factory rebuild in its original location, so they are planning to possibly rebuild in a different location.
Glad they're offering a wider variety of Russian 6L6 tube sets now. There was a fire at Shuguang, where the 440 was produced, and the factory is closed.
For the record, I've been using Reflektor-made 12AX7 tubes in the cathode follower stages of my Dual and Triple Rectifier Solo heads for years with no problems at all. I use Electro-Harmonix and Sovtek LPS types.
