Marantz Model 7T (1967)
A fully transistorized stereo preamplifier introduced in 1967 as the solid-state successor to the vacuum-tube Model 7.
Overview
The Marantz Model 7T is a solid-state stereo preamplifier introduced in 1967 as the transistorized replacement for the original vacuum-tube Model 7. Marketed as a "fully transistorized stereo control center," it maintains the classic Marantz design language while upgrading to solid-state circuitry. Built with Marantz's signature attention to detail, the 7T was designed to deliver high-fidelity audio performance without the maintenance demands of tubes. It was produced from 1967 through at least 1970, marking Marantz's transition into the transistor era.
