Sony TA-313 Integrated Stereo Amplifier Japan 1979 upgraded to 2 x 50 watts

This is the second Sony TA-313 amplifier I restored. The first one is in daily use in my system, it has a fantastic clear, warm and powerful sound. The original SI-1125HD module was replaced with two LM3886TF ICs ensuring a stabile, clear, very rich and powerful sound and boost the performance to 2 x 50 watts.
A carefully designed and engineered member of the Sony ‘TA’ series with a characteristic pair of analog VU meters on the front. The amplifier has a clear, powerful sound, specially it’s bass is spectacular.
This is a completely cleaned and restored item in excellent condition.
