Re: Let's not face what?

The 10Meg resistor in series with the EHT supply helps suppress excess current to the panels when charge migration starts. This is not required with the original ESL given the extremely high resistance on the diaphgraghm and you see no series resistors in place with the original ESL EHT unit.

Charge migration will never occur with the original ESL no matter the drive condition. This is not the case with the ESL63. Heavy drive will cause charge migration from the diaphraghm to the stator. The spark arrestor will stop the migration once it starts, but some migration and sparking will generally always occur under these conditions. The 10Meg resistor lowers the available current to the panel(s) and reduces the chances of punching a hole in the diaphraghm when charge migration occurs.
