Premium Vacuum Tubes

As of Feb 2021, we no longer directly resell Psvane branded vacuum tubes due to then declining re-tested specs for inventories we received, and no agreement can be reached then with the Psvane factory (rumor said that the factory was preparing for IPO hence chasing for sales volume and QC was oversighted. The IPO plan was eventually cancelled and not proceeded.)

Psvane now has adopted a more 'direct sales' mode and abolished much of the previous distribution method.
