Good progress. The sync separator fault has been fixed and now line timbase is locked to the sync pulses. It's not the same for the frame oscillator because the interlace circuits were removed during the early stages of the restoration process.
The ion burn: hopefully when the EHT is raised to the correct voltage the ion burn will become less visible.
