Full maintenance has been carried out, including the replacement of 53 deteriorated capacitors. Mark Levinson's No. 331L dual mono power amplifier. Genuine Harman product. It boasts ample and stable driving power with a strong power supply. The well-balanced mid-low range unique to this period makes me feel a high level of musicality not found in modern amplifiers.
