Cetron USA Made JAN 811A Vacuum Tube, New Old Stock

These are new tubes, and were part of the tube collection of an amplifier tech.  These were always kept in a good environment, and I have inspected each one.  White Richardson boxes, dated May, 1988.  All of the tubes in this listing are part of the same production run.  

This is a military grade vacuum tube (JAN means Joint Army Navy), and was manufactured under a 1988 Defense Logistics Agency contract.  

The box label shown in the photos is the same every tube box in this listing.

If you are replacing a tube in a radio amplifier, it's a good practice to replace them all with the same brand, as closely matched as possible.   

No returns on amplifier tubes.  Guaranteed not to be DOA, but otherwise, these are not returnable.    

Ships quickly and safely from Mississippi.
