Double-bearing capacitors that turn freely are best. Try to avoid using capacitors that have aluminum vanes. These are rather temperature sensitive, and this causes drift. Plated brass or iron vanes are better. A variable capacitor that is tight or "lumpy" when adjusted will cause backlash and frequency jumps.

5 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance …
