Quote:my 4 gang stators to frame measure 307.1 / 307.8 / 3.9 / 10.5 ohms not infinite.

These numbers do not look right. The first two sections should read a few hundred K. I see a 490K plus two 51K resistor in series to the chassis. The third section, has two coils and a 51K to ground. The oscillator section has two coils to ground so it will have a low reading.
