I just bought 2 Amperex 7119 to replace the 5687 in the I/V stage of my DAC-end. They have identical date code 81/20 on the glass.

I'm not quite acquainted with tubes. I noticed that all Amperex tubes are marked with "Amperex" in orange, but mine are marked with "AMPEREX", all alphabets are capitalised. Are they remarked tubes?

Can some kind soul help me out? Thanks in advance.

Hmm.. I wonder if mine are fakes ;)

I guess they change the markings from time to time. I don't know my date codes but I do observe that these two 7119s are identical except for the printing. They also have no marking etched into the glass.
