The EHT has gradually increased as I've been making improvements here and there, its now got to a point where it is high enough for the Visconel capacitor to break down. removing it from the circuit now completeley corrects the size and line linearity problems. And the brightness and focus are wonderful in comparison to how it was before.
There is still a small frame linearity problem which I think I'll try and track down next. I have an old EHT capacitor in my parts box - I wonder if it is man enough to replace the Visconel, it measures around 1nF but I cant see any voltage rating on it. I think it may be from a colour TV focus circuit. Any reccomendations for a suitable part to use for EHT smoothing?
First pictuer shows latest screenshot, secon shows capacitor I'm thinking of trying. David.
