I did check continuity on all coils that were accessible. I should have checked the second coil in the IF when I was replacing the 4 Meg resistor with the 2 Meg. Guess I have to take the IF back out since there is no way to test it without a resistor in the circuit. However, I just noticed a wiring discrepancy - The second IF coil shows a center tap connecting to the trimmer (15). My trimmer only connects to the IF at one spot (not two) and the bottom connector of the trimmer is grounded, but no second wire. Any idea why it's missing?
