Updated 8/30/2019:
Ran my first preliminary test of the new Legacy Powermaster for District 6. This device is connected to a PowerHouse 135 whose connector I repaired. The test went very well. The Powermaster took its address programming without incident and came up correctly at 20VAC. I will probably set the maximum power to the track at 18VAC.
The assembly of the Molex connector for the PowerHouse also proceeded without incident. So far, so good.
More when I know it.
