Try a Google search for CRT suppliers. Can't recall the name of the one I
found, but there were a couple that are able to cross reference the numbers
and can tell you which of the two is actually the CRT number.

I need to replace the CRT in my Tenma 72-6602 oscilloscope.
It goes by two numbers. They are 75AWB31 and C312P31B.

Googling finds no one who sells them and very little info.

Anyone have a spare laying around or know of a more common
substitute? I would like to swap for or purchase outright.

Any help or suggestions appreciated.
