Mosyt likely GE.
"IBM did the final assembly, but more than 400 companies supplied parts and
subassemblies for its computers, including GE for vacuum tubes and 3M for magnetic tapes.?

Good question. They have an IBM logo and "Made in USA", along with the
part number (5965 or 5963) and a bunch of numbers that might give a hint
as to manufacturer. Any suggestions on how to decode them?
These came to me from my father, who worked in the Vacuum Tubes
department at GE for a while when I was growing up, so there's a good
chance the OEM was GE.
While
going through my assortment of old vacuum tubes looking for audio
treasures, I found a handful of IBM branded ones. Mostly 5965, but
there's one 5963 mixed in.
Who made them?
