Excellent condition package Includes: - Technics SE-A7000 MOS Class AA Power Amp, 240 Watts Per Channel Minimum Rated at 4 OHMS (.005 Distortion). 38 kgs/ 84 pounds. Using newly developed MOS class AA circuit MOS class AA circuit is mounted. The class AA circuit realizes high power and complete class A voltage control by amplifying the voltage of the music signal input from the source and supplying the current to drive the speakers with separate amplifiers. The MOS class AA circuit is based on this class AA amplifier. The voltage control amplifier uses a new element, MOS FET, which is an amplifier with extremely high input impedance and excellent high-frequency characteristics, to further enhance the linearity of signal control. The bipolar transistor improves the speaker drive power by supplying a strong current, and realizes a stable high output. Ten large-capacity electrolytic aluminum capacitors of the newly developed MASTER series with a total capacity of 75,000 ? F are installed. Mechanical properties of this condenser have been improved by using newly developed special damping aluminum for the case. Three power transformers are installed, one for each current supply amplifier for left and right channels, and one for voltage control amplifier for both channels. These transformers are made of oxygen-free copper wires and are highly regulated by high-density, high-efficiency technology. Furthermore, they are enclosed in a 3-layer magnetic shield case with special resin to suppress mechanical vibration and leakage flux and greatly reduce electrical noise. 3 mm thick weight class top plate, high rigidity chassis, large insulator, side wood with real wood mirror finish, etc. are adopted, and magnetic radiation and mechanical vibration are greatly reduced. Equipped with balanced input terminal. This terminal achieves stable transmission by using a balanced transformer method with a DL-type permalloy core and a tight shield to prevent the influence of external magnetism. It is equipped with a high precision large power meter with 10 mm thick bronze glass. This meter can read directly from 0.0001W to 300W. OFC bus c bus bars and LC-OFC internal wiring. Electronic speaker selector is used. Highly reliable gold-clad contact is used for terminal switching. In addition, large gold plated terminals mounted on an aluminum base are used for speaker terminals. The internal construction makes the left and right channels independent independent left and right channels to reduce noise and crosstalk between the two channels. Newly developed non-inductive resistor is adopted. By increasing the alumina content -frequency response by preventing signal reproduction from being hindered by Joule heat generated by itself by increasing the alumina content of the base insulator. Uses a PC-OCC power cord with polarity indication. - Technics SU-C7000 Battery Drive Control Amplifier (.001 Distortion). 17.5 Kg./ 38.6 pounds. A battery-driven power supply system is used for the power supply. By completely separating the AC power supply from the signal circuit, noise loops caused by the connection code and AC power supply and switching noise of the power supply circuit are eliminated. The battery can be fully charged for approximately four hours, and automatically switches to AC power when the battery is low and starts charging. R-core transformer is used for the power transformer. Since the cross section of the core of this transformer is circular, the magnetic flux is uniform and there are no joints in the core. Therefore, the leakage magnetic flux is extremely small. This reduces noise caused by the leakage magnetic flux entering the amplifier circuit. A resistor rotating volume is used for the volume. This volume has a unique structure that rotates the resistor, reducing by half the number of dissimilar metal joints that cause sound quality degradation. In addition, the resistor is made of fine-particle carbon, which greatly reduces distortion. In addition, vibration transmitted to the brush is prevented by the heavy case of zinc die-cast with gold plating. In order to reduce adverse effects caused by vibration outside the amplifier, a THCB (Technics Hybrid Construction Base) is adopted. Excellent vibration damping characteristics are realized by a multi-layer structure consisting of a chassis, a vibration isolation base and a copper-plated bottom chassis. In addition, a large ? 60 mm insulator and side wood using bulk mold compound protects small signals from external vibration, and a 2.8 mm thick top plate protects electromagnetic radiation. Equipped with balanced input / output terminals. Uses a balanced volume with an ON/OFF switch. The phono equalizer amplifier and flat amplifier use the classAA method. Equipped with a battery voltmeter with AC/DC/Charge display. The relay uses a silver-palladium and gold-clad contact relay sealed with nitrogen gas. Glass epoxy gold plated printed circuit board is adopted. Uses a very thick PC-OCC power cord with polarity display.
