Remarks[edit]

Most powerful model in Harman's PM series. Typical problem: scratching, noise and partial channel failure due to oxidized switches. Power transistors as spare parts only very limited available. Elkos usually no problem. One of the best integrated amplifiers ever built with an incredible amount of "steam and pressure" and a very good phono preamplifier. Even today, it does not have to hide from much more expensive noble devices.
