Here is one of my better units in my collection, it's the Marantz 4140. They were made from 1973 until 1977, and the Marantz dealer MSRP was $549.95 in 1975. It pushes a true and clean 25 watts x 4 channels, or 70 watts x 2 channels. The power bandwidth is from 7hz to 70 khz, and only has an IM (Intermodulation Distortion) and Total Harmonic Distortion (THD) of 0.5%.
They don't make them like use to, that's for sure.
