ℹ️ Overview This is a stereo power amplifier released by Technics from 1975 to 1976. The unit's dimensions are width 450 x height 173 x depth 380.5 mm, and it weighs approximately 15 kg. The rated output is 76W + 76W (stereo both channels operating) at an 8Ω load. It's 93W + 93W at a 4Ω load. The frequency response range is 5 Hz – 100 kHz, the total harmonic distortion (THD) is 0.08%, and the signal-to-noise ratio (SN ratio) is 110 dB. Features and Design A major feature of this amplifier is the "4-step output impedance switching" function. By switching the output impedance, the speaker's damping factor can be adjusted, designed to bring out the speaker's performance. The circuit configuration is a direct-coupled configuration of "differential amplification → fully complementary OCL". This enables low-distortion, highly stable amplifier operation. The power supply uses a ±42V constant voltage power supply and is equipped with a large-capacity transformer and large capacitors to ensure the output stage's headroom and stability. Built-in output meter (peak meter). Because you can check the output level in real-time, it is favored by audio fans who "want to visually grasp the volume/output." 【Condition】 Sound output from main/remote has been confirmed. Left/right levels are OK. There is some crackling when adjusting the level. Other detailed operations have not been confirmed.
