Harman Kardon Pm650 Review, The majority of Japanese transistor amplifiers are biased cool, typically between 10-30mA per output device. Suggestions appreciated. If the value is not available, then Nippon Chemi-con KZN. The PM660 is perhaps unique among modern amplifiers in its use of discrete transistor circuits rather than integrated circuits throughout. It also features a high-cut filter and two-way tape copy capabilities. I would suggest that you check and adjust the bias and offset as it does tend to wander over the years and replacement outputs are not easily found. They are superb e-caps.
