There are tubes, and then there are tubes!
Back in the "dark ages" (60's & 70's - my HS & college days), I used my 1st Class Radiotelephone license to work as an engineer for several 50KW clear channel AM stations in the Philadelphia area.
Their transmitters were so big in the pre-solid state days that we actually walked inside the room-sized cabinets and took off all our jewelry before entering (to prevent RF burns). We had to wear white linen gloves to touch any of the tube glass parts, because a broken tube could explode violently. (No OSHA in those days?!)
