Default Re: Yet Another Bush TV22

Looking at my line scan it is compressed in the region that I assume is that corresponding to the transition from scan current taken from the boost capacitor to that from output valve. The nominal value of the boost cap is 2uF so I thought I would experiment with its value to see if I could alter my compressed region. I tried increasing to 3uF and also decreasing to 1uF but was very surprised at how little effect there was on the line scan.
