wa2ise is an invaluable source. His web pages have been very helpful.
I don't think the bandwidth of the CRT is as much of an issue as trying to get the CRT focused well enough. The bandwidth is limited by the grid capacitance. The higher frequency would require a change in the video output circuit. It needs to have a lower output impedance to drive it at the higher frequency. John
