Change from 20 pF to 82 pF, so that can be used in stock configuration with "small coils" (single-turn loop 8µH+1.5Ω AC resistance). Higher-inductance control loop tunings with lower crossover frequencies only need larger capacitances than this, so not being able to go lower than 82 pF isn't an issue.
