Mitsubishi M-04 Mini Stereo System

The M-04 was a heavyweight, high-quality mini component system from Mitsubishi Electric. I'm pretty sure it's from the early 80s. It includes the M-P04 preamplifier, the M-A04 amplifier, the M-F04 tuner, and the M-T04 cassette deck. Just the amplifier alone weighs 7.2 Kg. Output power is 2x50W (minimum) into 8 ohms from 20Hz to 20kHz with no more than 0.02% total harmonic distortion. This increased to 2x60W if using 4 ohm speakers. The Dolby-equipped tape deck has a frequency response of 30 to 15,000 Hz when using metal or chrome tape.
