The DC Restorer caps are C881, 2, 3, 5 and 7. They go between the main (A1) board and the HV auxiliary (A5) board. In my experience, they are more likely the problem than the diodes on the A5 board. But replacing the caps is a bear. By coincidence, I am doing the final edits of a video on replacing two tantalums on the main board which are under the A5 board and require removing the A5 board. I will add this intensity problem to the video, which I hope to get out today.
