An unused new old stock (NOS) GS-31b / GS31 transmitting tube.

Prior to sale we run each one up heaters only on a test rig with full cooling applied for a few hours. So when you get the valve it can be put into immediate use with full voltages.

Note this is for the valve only without the aluminium anode cooler. This is available as an extra if required.
