i could not modify my message, anyway, will a 29 inch TV fit on the cabinet plastic bezel, Cu's if so i can get cheap TVs here, thanks allot.
I've done exactly this and it is actually much harder than it seems. Unless you get a tube of exactly the same size and shape as the original, you'll have to do some modifications to the hard black plastic bezel which is both a pain and very time consuming. What I did was to fit a Philips 29" tube, only to find that minor shape differences meant that the top lid would not close down properly 
A better bet might be to find an old 29" Toshiba TV, dead or alive, as I understand that Nanao sourced their tubes for the Astros from Toshiba. This way the tube is more likely to fit your Astro, and might even have the right yoke characteristics for your monitor chassis. Look at the dump or revolve/recycling station, scout ebay etc, All you need is a good screen, the rest can be kaput. There might even be other brand TVs that used Toshiba screens.
Even if the Toshiba tube won't work with your chassis, Joey at Jomac can probably fix you up with a new dual-res chassis at a reasonable price.
thanks for the advice,
