My Acom 1000 manual says the 4CX800A and GU74B are different numbers for the
same tube.

IIRC
there never really was a 4CX800, that was just a label given to the
Russian
tubes since that described them in 'Eimac' terms.

At least in pictures, 4CX400 and 4CX800 had those numbers on the tubes.
Though it would not be hard to make a rubber stamp and roll the cooler
over it for pictures sake. Maybe use paint instead of stamping ink on
the stamp.
