Yes Dan, you are correct. I often think backwards when discussing the stator. The rotor plates are connected to the frame by the spring leaves between each gang. Then the frame is grounded. The stationary plates are connected to their respective circuits. BTW be sure to swipe a small piece of solvent soaked printer paper between the leaf spring and the frame to remove contaminants. It clears up noise when tuning around the dial. But you said you don't have scratching when tuning. Maybe the 89 tuning cap wasn't advanced enough to have these refinements.

Terry, is that a rhetorical question? Doesn't the signal strength depend on the turns ratio (within limits of course)?
