NOT electrolytic. It is a standard paper/foil capacitor. The line, as said previously, indicates the connection that is connected to the foil that is on the outside of the rolled foil/paper. This end of the capacitor is normally connected to the lower impedance to ground in the circuit. By doing that, the outside foil acts as a shield for the higher impedance side of the circuit, thus reducing the chance of outside interference (hum.)
