Brand: SONY
Model: TA-F777ES
Year: 1983

The TA-F777ES was introduced in 1983 for the Japanese market and it marks the start of a long series of ES integrated amplifiers. Responsible for the design of this model was Mr. Takashi Kanai (died in 2022) whos' first product designed for Sony was the TA-AX6 from 1981 but, he was still active with Sony in 2002 when he was working on the S-Master Pro digital amplifier. One of the highlights of the TA-F777ES was the "Audio Current Transfer" construction. As a consequence of the adoption of the Audio Current Transfer circuit and the linear gain control type attenuator, allowed the volume adjustment so the impedance decreases as the gain is reduced. As a result, various characteristics at the volume position in actual use are improved.
