TECHNICS SU 50A Stereo Integrated Solid State Amplifier Vintage 1969 GOOD LOOK TECHNICS EAA-2010/SU-2010/SU-50A/ TECHNICS 50A ¥95,000 (released in June 1969) ¥95,000 (around 1970) Working perfect, All Refurbished Work On 100/120/220/240 volts AC VERY RARE Vintage Amplifier with New GREEN LED lights Like MCINTOSH! This solid state pre-main amplifier was created by integrating the development technologies of the TECHNICS 10A, 20A, 30A, and 40A tube type amplifiers. The model number has been changed 3 times: EAA-2010, SU-2010 and SU-50A. The main amplifier section uses a two stage differential amplifier circuit and an OCL circuit with a two power supply system. All stages are directly connected. The circuit configuration without an output capacitor improves low-frequency characteristics and improves stability and linearity. The equalizer stage of the preamplifier amp section is composed of 3-stage direct connection NF type using low-noise PNP transistor, which solves the shortage of dynamic range and obtains high S/N. The tone control circuit is based on TECHNICS ‘s original method using special double volume. This system has a special structure that combines a silver conductor and a resistor. At the midpoint, both brushes touch the silver conductor, so that all capacitors are removed from the circuit to become a resistance-only circuit, resulting in a flat characteristic. A protection circuit using four transistors and two diodes is mounted. This circuit is equipped with an automatic control and protection device that detects the operating point of the power transistor to maintain safe operation, an automatic correction circuit for temperature changes, and an instantaneous recovery type so that even if an excessive current flows, the signal only clips and operation is not interrupted. The front panel features push-button input selection buttons and a large volume knob to improve usability. In addition, it uses a design in which the letters on the front panel come out when the switch is turned on. The pre-out terminal is equipped with two systems, a Low terminal with a rated output of 1 v and a High terminal with a rated output of 5 v. It is equipped with 4 AC outlets. Equipped with two types of speaker connection terminals.
