Sansui AU-317 Integrated Amplifier w Rack Handles An 1978 Hidden Gem 50W RMS
Sansui AU-317 Integrated Amplifier w Rack Handles, made In Japan in 1978, a real hidden gem, rated at 50W RMS - Rated 5 Stars in many places by audio folks. This is a hard to find item, and this one has the optional rack mount handles (about $60 add). This AU-317 is in good working order, cleaned, reviewed and tested recently by DALAUDIO. Please see photos, this Sansui integrated is superbly manufactured inside and out. The original complimentary TO3 package Sanken 2SA745/2SC1403 transistors with close Mfg No. (730/740) are intact.
Why does this sound so good? A huge power transformer, Nichicon filter caps, Darlington arrange power output proceeded by a Sansui inspired/ patented differential push pull driver with current mirror circuit! That's what really makes this beast roar!
Features: This 1970s amp has some really nice features!
- Subsonic phono position on the actual input selector
- Tone defeat that truly removes the entire tone/equalizer sections
- Front panel TRS input mixer with level control
- Preamp/Amp Strapping - to place an equalizer post preamp, or to utilize the preamp or amp section independently
Sound: Fidelity is clean with lifelike presence. Volume is strong and clear, even at low levels. The clarity and depth of sound is hard to find in amplifiers today. The Sansui components of the late 70's were and still are truly awesome. The power rating on this AB amplifier is clearly conservative, as it will perform like amps with much higher power ratings.
