Thanks John

OK this is good info for me. This 30Khz signal, I see that I am comparing to vertical and horizontal signals. Is this 30kHz a refresh rate?

For instance here is a spec of a recent 17" CRT monitor, viewing on ebay.

Synchronization Range - Vertical 50 - 120 kHz
Synchronization Range - Horizontal 30 - 70 kHz

I presume the scandoubler can increase the frequency x2 so this is how you get 31kHz? Could the above spec CRT cope with A1200 output with scandoubler ?

Im finding it difficult to find a NEC CRT within sensible driving distance...
