Military versions are highly sought after because they are made to military specifications and go through testing before they leave the factory.

Actual picture. I have been asked why my tubes mostly read 120, I literally go through thousands of tubes and find the rarest tubes that read at the highest readings I will be selling groups of used tubes in the future.This tube is tested on a sencore mighty mite VII to be 120/120 on both sides. 50-70=Questionable  70-100=Good 120 is the highest reading possible!  Feel confident in the readings because the MightyMite VII tests at full load current drawn through the tube and can detect weak tubes that other testers might not. These are tested to be in guaranteed working condition   Returns accepted only if not as described, see details below. I have had great luck with USPS delivery and I always use delivery confirmation, However you purchase is 100% your responsiblity after I put it in the care of the delivery service, which means your only 100% assurance of refund if your item does not arrive safely is insurance. This is my way of saying that I cannot be held resposible for lost or damaged shipments. I reiterate that I have not had a problem but that actually increases the probabily of one occuring and also indicates the low occurance of lost or damaged shipments:}   If you have any questions or comments contact me on E-bay Presence01     Check out my other 12Ax7 12AT7 12AU7 12AZ7 12AY7 6V6 6L6 2A3 ECC81 ECC82 ECC83 6DJ8 6SN7 6SL7 422A 421A including Military tubes AND OTHER GREAT TUBES FROM THE 40'S 50'S AND 60'S Check out my other items!
