I was just thinking last night .... all old pre-aluminized B&W sets seem so
extremely dim. The ones I saw at the ETF convention were all about the
same brightness, no match for a modern LCD set. OF course even in 1949
a CRT could be very bright (e.g. the ones used in projection sets).
So I got out my camera and measured the brightness of a white area
on my LCD and the 9T246. It was 6:1.
Then I looked at the specs for the LCD set and the 10BP4A.
comparing the peak brightness spec for the 10BP4A to the spec for the
LCD ... they are identical! Is the LCD set being speced for
say an 18% gray? That would make the measurements match well.
Does anybody know?
