marantz Model 2600 (1978) - A Powerful Monster

 

stereo receiver

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.

marantz Model 7700-2 - The Invisible Tape Recorder

tape recorder

The marantz Model 7700-2 is a unique tape recorder that was never mass produced for the general public. It only made a few appreances at audio fairs like the Japan Audio Fair from 1978 or the Consumer Electronics Show from Las Vegas. A few audio magazines (USA, Germany) gave more details about this special model that came much too late from a company that has never manufactured a reel to reel recorder. Only 10 machines were built in the Japan development laboratory. The marantz Model 7700-2 was a 3 head 3 motor dual capstan construction tape recorder. Recording was only possible in 2 track mode but the HBA-2 head assembly had also a 4 track head but for playback only. For optimal recording settings there was a built in test oscillator with 400Hz and 10,000 Hz signals while the needle type meter has VU, Peak and Peak Hold settings. The tape recorder has 3 speeds: 38, 19 and 9.5 cm/s and pitch control with a +/-6 % range. The azimuth of the recording head can be adjusted with the help of the built in test tone. Frequency response is (+/-3dB) 20 - 37,000 Hz (38 cm/s) 20 - 29,000 Hz (19 cm/s) and 20 - 17,000 Hz (9.5 cm/s). The initial price in 1979 of the marantz Model 7700-2 was 3200 DM in Germany and $2500 in the USA.
