AMCRON/CROWN M-600
¥ 891,000 (around the late 1970 s)
Commentary
A monaural power amplifier developed by combining AMCRON's technological capabilities.
Especially designed for durability and stability, the minimum compensation value of 1 with minimum compensation value of 1 kW.
In addition, the newly patented output bridge circuit is adopted, and extremely stable characteristics are obtained even in continuous use at high power levels.
The power supply section uses two 1 kw power transformers and a computer-grade condenser.
The input section is modularized by plug-in method, and standard specification is equipped with AC-DC input selector switch and input gain control.
There were also filters, oscillators, servo amplifiers, etc. as options.
