Sorry. But I found that funny considering the difficulty I had making extension cables and propping up the chassis so I could test it. I made a high voltage extension with a length of high voltage wire and connectors made from strips of metal from an orange juice can shaped to make a receptacle for the wire to the CRT and a plug to fit the socket at the HV rectifier. The receptacle is covered with multiple layers of heat shrink tubing. It works well with no corona discharge and allows me the flexibility to prop the chassis vertically to the rear.
Perhaps if there is sufficient improvement with the DC coupling it may justify your pulling the chassis again?
