Checked and rechecked the filters for a miswire but came up empty. I've gone through the resistors from the sync tube through the vertical output tube and they are all where they need to be. This one's a real .

I recently acquired a B&K 1077 so I can show what a regular picture looks like now. I had prevously thought that the vertical was running too slowly but you can see now that is not the case. The horizontal white bands do not roll with this signal, instead they are steady right where you see them.



Any thoughts?
