re: Power Line Four

My favorite amp for the last dozen years. The PS400 is the same circuit with some external changes for the pro market such as 1/4" inputs, terminal strips in addition to binding posts and a round socket for add on modules. A thorough update of the Crown DC300A, the circuitry from the input jack to the drivers was changed. The tough output section was retained.
