Thanks Jeffrey for the info.
At the moment I'm running just under 5kv final anode volts, the frame scan is pin sharp but a little duller near the centre of the tube. I'm aiming between 6.5-7kv which hopefully will cure the unequal illumination. The little Chinese EHT DC to DC converter can supply 50uA without sagging and I'm pretty sure it will do the job, so line scan can be independent of EHT. I'm also hoping that the eventual outcome will mean I can do at least 405 & 625 lines.
