RCA 12AB5 Tube, New, 1966, Hickok Tested

Good, new 12AB5 tube from RCA.  Made 1966.   Tested good on a Hickok machine

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.
If you need the original box, be sure to let me know before ordering this.  Sometimes I will replace a shabby original box with a new, more durable white box for shipping, so if the box matters to you, be sure to let me know so I can include it (if I have it).
This will be packed safely.
Ships quickly from Mississippi.
I have been selling on online for over 25 years, so buy with confidence.
And yes, I will gladly combine shipping.
