[Test-Equipment] replacement CRT for HP 8563E

[W2HX]

This is an interesting question. I have seen an 8560E (not EC) on ebay that was converted to LCD. As far as I know, Simmcon does not sell a model for the 8560E.  Does anyone know who made an LCD kit for the 8560E an does anyone know what resolution should be expected with such a kit? I know that Simmcon offers VGA and XGA.

To the original Op's question - if an LCD kit could be found, that might be a good solution to your weak CRT.

Thanks
Eugene

Hi All,

The CRT in my 8563E is getting dim, and I have been looking for replacements.  I have no other distortion, so I believe this is due to the CRT becoming weak rather than being a voltage problem.

The 8563E manual lists the CRT part number as 2090-0225 which cross references to a Panasonic 170XB31.

I have found some Panasonic 170XB31 parts that may be available, but they are labeled with part number of 2090-0236 (in addition to 170XB31).

Does anyone know if this change was just a change of part number without functional change?

The real question is whether or not the 170XB31 labeled will work in my 8563E which has listed CRT part number of 2090-0225.

I have not opened the SA to check what tube I actually have, because if the answer is a simple "you can use these tubes interchangeably", there is no need to do so.

And because I am not certain I can actually get these parts, I did not want to open it unnecessarily.

Thanks in advance,

Roger Rehr
