Good question.................

My friend is an Engineer at Raytheon and very sharp. He explained the difference to me and advised to check and see if a GT or not is actual spec. People find all kinds of tubes in wrong sockets so not surprising in these old things someone sticks in a glass for a metal, same numbers right?
