Tube size question
My understanding is that the WTDS indicates the visible size in centimeters. However, the Wells-Gardner D9205 monitor is described as being "33 inches," but has an A80AEJ15X08 tube in it, which is 31.49". 6That's quite a bit less than I'd expect would get rounded up to 33".
Is there something I'm missing here? Perhaps the size is measured laying directly across the screen, which would add an inch or so due to the curve of the face. |

US - it's the diagonal viewable area, as defined by US Code from 1967, first used in 1968 model adverts. Canada/Europe - I honestly don't know. A80 CRTs in the US are 32", A63 is 25", and A91 is 36". Rounding is allowed.

Maybe what you have is a post-sale-to-consumer Canadian import...The canucks never passed the screen size laws we did so their tubes are usually labeled as ~2" bigger than the same tube was here in the USA.

I am not sure if monitor tube sizes in the US were required to be stated as viewable diagonal rather than over-all diagonal at the same time as TV tubes. Anyone recall?
