There is provided a radio frequency signal amplifying device consuming less power and operable at a high voltage in a PA driving amplifying apparatus applicable to a PA amplifying circuit which amplifies power of an RF signal. The chemical drying time can be substantially reduced if such a catalyst system is added to the coating, wherein preferentially such a catalyst is a transition metal complexsalt, like Mn. The second edge E2 and the third edge E3 are disposed concentrically with the first edge E1. In another embodiment, the wine or spirits are in contact with the inner surface of the tubes and the atmosphere with the outer surface.
