Thanks for looking at our item!

This is an Eimac 2X1000A High Vacuum Rectifier Diode Electron Tube. The tube is NOS, in its original packing material. Its missing its box. Its in very good condition - a beautiful tube. The tube's cooling fins have some slight denting (see pictures).

We used a current-limiting power supply to carefully functionally test the filament/heater. We momentarily applied the specified voltage and observed that it was drawing current, and we have every confidence that this is a functional NOS tube and back it with our warranty.
