Model 65 alignment
#8

As you open (counterclockwise) the trimmers, you should be able to tune the main tuner down the dial to get the same station. This is because opening the trimmers reduces the capacitance in the circuit, so you need to add more with the main tuner to compensate. That your trimmers are not allowing for this is puzzling. Even more puzzling is that looking at the Rider's schematic for this chassis, it shows no trimmers at all. :-/
