Wound 25 turns on the Ameritron filament choke with approximately 25.5uh inductance at 1.900mHz.  This is the 3rd winding.  Couldn't wind it exactly in the space between the existing turns because they were spreading apart.

Test results
1K ohm carbon resistor
1.900mHz
Before resistor- 6.4v
After resistor- 2.8v

Carbon Potentiometer set to 600 ohms.
Before Pot- 6.2v
After Pot- 3.2v

Thoughts?
