Hi David,?
For folks not here in the US the adjustment as I described works fine but requires a way to monitor current draw. A bench supply is good or any of the small inexpensive meters will do inline for the Gemini power cord.?
The spring loaded OPWs resolve the issue once and for all, everything else is still a compromise and requires seasonal adjustment.
