Hi,

I tried, with a large range of capacitor...
I get roughly 2 cases

1/ the image is unstable...
2/ the image is stable
      but when the image is stable, I always have 6/7 columns missing on 
the left...
     the value of the capacitor does not change the number of missing 
characters...

all the converted I tried have the same problem with the same number of 
columns missing
