Hi,

Still fighting with the cp110, but in meanwhile I worked also on the md1.1. Afterall, it was a gassy tube. Beside the bad focus it also had problems with color smearing, some change in the caps at the emitter of the rgb drive improved things a bit, but focus remained avarage.

While Removing (carefully) the crt panel to try a rejuvenation, i heard some sissing/ticking noise. I think it was already leaking for a long time a very little, but removing de CRT panel made it worse so does the focus . .

End of the story for the md1 sadly . .
