    20180825_110224.jpg Tagging artifacts this morning from a US site used by US military, but also had civilian presence. I am guessing this is a radio tube deposited 1942 - 1945.

    If anybody has an suggestions as to tube age, use or ID, please give me a shout. Leaving lab around 3 cst.

    Thanks

    The size of the pins puts me in mind of the UX series of sockets. I was familiar with them earlier in my life in the UK. Some had four pins UX4 and some 5 UX5. That’s all I have for you. :)

    Thanks. Its an RCA tube. RCA UX 277 looks close, but its not it. Spent an hour looking last night. Fascinating stuff.
