Sansui - AU-317 - DC Solid state integrated amplifier

Sansui stereo amplifier AU-317\r
Unit in good working condition and has been recently revised and serviced by a professional Technician. \r
This is what has been serviced to the unit for own records: \r
\r
- Recapped the audio output stage with state of the art Japanese Capacitors \r
from Japan. \r
- Replaced 2 x Power End stage Transistors. Replaced several signal Transistors. -- Replaced several rectifiers. \r
- Recalibrated the bias. \r
- I was able to get 59 Watts x 2 @ 8 ohms before clipping with 1 KHz sinewave \r
input source. \r
\r
\r
All this service comes to a cost for a good working machine. \r
\r
All pictures are original of this unit and part of description so what you see is what you get ! \r
