Marantz SM1000 Stereo Power Amplifier
⭕ Marantz Sm1000 Stereo Power Amplifier (ESOTEC Series), which supplied all the technologies which a Marantz of those days has, eliminated all the cost restraints entirely and developed them.
The first and second stages of the Sm 1000 are push-pull differential amps with dual transistors, both stages are coupled with an emitter-follower buffer amp.
The final stage ouputs 2x 400W (8 Ohm) with 36 bipolar output devices (NEC 2SD555 / 2SB600, 200W each) driven by 12 drivers parallel-connected and organized in Super Linear 3-stage Darlington construction.
Theres a dual supply rail to cater for momentary high-output needs where a voltage which is higher than that fed to the final stage is fed to the main voltage amplification stage..
Also inside this 42 kg monster are glass-epoxy PCBs, oversized logarithmic compression meters, two cut-core 800VA transformers, four 20.500µF / 125V caps and the Tunnel Heat Dissipator and its low-noise fan, developped by NASA! The main capacitor array is hooked to a big, thick and fat copper plate.
The item is used, previous owner has damaged four upper binding posts to use a modern speaker cables with large spades, except this overall condition is excellent!
Designed In U.S.A., serial number 01F030004, AC 100V ~50/60 Hz!
MSRP in 1979 was 950 000 yen!
