About this model

Despite the title, the Marantz 7 is a preamplifier. It debuted in 1958, the year stereo records reached the public, and according to Sound & Vision it sold more than 130,000 units over a run of more than twelve years. Its six 12AX7s are the tubes owners most often change, and this original-owner example, serial 7-17912 from the early 1960s, had a matched set of Sovtek 12AX7s fitted.

It came in its original wooden cabinet. Serial numbers matter on Model 7s, so keep a note of it; collectors use them to date individual units.
