About :
Repair of a wonderful amplifier Yamaha A-2000A born in 1983. It has good characteristics for that time 20Hz-20kHz 150W + 150W 6 Ohm 0.003% THD 170W + 170W 4 Ohm 0.005% THD 1kHz 160W + 160W 6 Ohm 0.002% THD 180W + 180W 4 Ohm 0.002% THD Damping factor - 200 Signal-to-noise ratio of the amplifier 106 dB This was achieved thanks to a circuit of two amplifiers per channel connected like a bridge. One half is class A with a low-voltage power supply of +-4V, and the other is class AB with a power supply of +-60V https://vk.com/@-122241235-remont-usi... you can read more about it here. The whole problem with this amplifier is in the crumbling soldering and hygroscopicity of the compound around the massive components. A lot of things have rotted under the latter.
