Nakamichi SR-4E Remote Control Stasis Stereo Receiver (1987-89') Test after power and amp repair

The Nakamichi SR-4 redefines the word receiver. It offers the same convenience and economy but it&designed like separate audiophile components, each individually optimized, each individually powered, each isolated for minimum interference. And what a receiver: Stasis power amplification for uniform impedance, inherent stability and tremendous peak-current capability, a moving coil/moving magnet phono preamp with precise equalisation, an effective subsonic filter and more!
