GE 6BW4, 1965, Hickok Tested Good

GE 6BW4 tube made in 1965, plant code 188-5, no dots.  Both tube tests (plate 1 and plate 2) were run successfully.  Gray plates, halo getter.

This tube has been tested on a Hickok 533A machine.
In order to be sold as NOS, it must be new old stock, filament continuity must check good, it must be free of shorts,and read solidly in the GOOD range.
If the tube is used, the same checks are made before marking it as good.
The sale is for the tube only, the box is included for good measure (if I have it).
If the original box shows in the photo, the tube will come in the original box. Expect boxes to show signs of wear and storage.
Shabby boxes are often replaced with newer white boxes for safer shipping.
This will be packed safely.
Ships quickly from Mississippi.
I have been selling on online for over 25 years, so buy with confidence.
