{"title":"Marantz","description":"\u003cp\u003eMarantz was founded in 1953 in Queens, New York, by Saul Marantz, after demand for his hand-built Audio Consolette preamplifier led to the Model 1 preamplifier in 1954. The company followed with the Model 7 stereo preamplifier in 1958 and the Model 9 power amplifier in 1960, and became one of the best-known names in high-fidelity audio. Marantz was sold to Superscope in 1964, merged with Denon in 2002, and has been part of Harman since 2025. This collection carries Marantz-marked replacement parts, including TO-3 audio output power transistors, for service and restoration of vintage Marantz receivers and amplifiers.
