The marantz Model 2600 from 1978 was the most powerful stereo receiver by marantz (owned by Superscope at this time) and it was almost the most powerful receiver from the "monster receiver" era. (The most powerful was the Technics SA-1000). The Model 2600 is an updated version (with added Quartz Locking tuner circuit) of the previous Model 2500. Powered by a Toroidal Dual Power Supply, Turbo-Flow heat dissipation system, 9 kHz 18 dB per Octave Bessel-derived high filter, 15 Hz 18dB per Octave Butterworth-derived low filter and variable tone turnover points will deliver 300 Watts per channel into 8 ohms, Minimum Continous Power from 20 Hz to 20 kHz with no more than 0.03% THD. The FM section features Quartz-Lock tuning system, Phase Locked Loop multiplex demodulator, 5-Gang dual gate MOSFET FM front end as well as a 2-inch Oscilloscope Display from Hitachi. True Power is the capability of a receiver to deliver more power into 4 ohms than into 8 ohms according to FTC regulation thus the Model 2600 will deliver 400 Watts per channel into 4 ohms. This huge receiver measuring 490*177*438 mm and with a weight of 32 kg was designed in the U.S.A. and produced in Japan. It's original sale price was 2998 DM in Germany. An optional walnut veneer cabinet, the WC-124 was also available.
