Info needed on very large tube

(1/1)

mtnman37879:
I just acquired three very large vacuum tubes. They are Federal Telephone and Radio
F-124-A. All three of these tubes are in the shipping crates. I got them at the Y-12 plant at Oak Ridge National Labratory. I am in need of info such as what were these used for? When were they made? etc. Thanks in advance, Patrick
