MARK LEVINSON No29L 595,000yen(1990 release)

Stereo power amplifier which supplied the know-how acquired by No20.5L, and was developed.

The highest-class switching grade filter capacitor of the quality toroidal transformer per single-sided channel "rated 320VA" and a total "60,000 micro F" is adopted as a power-source part.

The filter capacitor of an input stage, a balance input stage, the voltage amplification stage, an output stage, and a power-source part is arranged on one substrate for every single-sided channel from the input terminal,The wire product line in which a signal flows is only only 26.7cm (cross-section of 10mm 2OFC) from an output stage to an output-terminal. The failure by the interference and impossible leading about between product lines is suppressed by this.

By always considering it as a Class-A operation, the voltage amplification stage and the driver stage have controlled the output stage, and are suppressing distortion. In addition, the output stage serves as AB class operation.
