for. Trimmer capacitors are still the best way to achieve optimum circuit performance at the least overall cost. For instance, after burn-in and temperature cycling, crystals can drift but can be brought back to the exact frequency with trimmer capacitors. Trimmers have taken their share of knocks over the years on several counts.
