    *LOCAL PICK UP PREFERRED*
    For sale:
    (1) Sansui AU-717 Integrated Amplifier (Professionally Restored — Scroll Down For Restoration Details) — unit was tested using an oscilloscope with a 1kHz signal — results: 110WPC output without any clipping! BEASTLY!
    (1) Sansui TU-717 Tuner
    Condition: excellent; from a non-smoking home; always loved and never abused. Selling as a set — I will not separate. Scroll down for disclosure and specs.
    Important Disclosure: I have described my gear for sale with the utmost accuracy — it is in great working order and ready to be enjoyed. The integrated amp had been professionally restored and is ready to be enjoyed for many, many years to come. The tuner is in good working condition, and pulls in radio stations with ease. That being said, vintage audio gear must be maintained and will likely require basic servicing at some point in the future.
    NO RETURNS.

    Sansui AU-717 — SPECS:
    Description:
    The AU-717 amplifier incorporates an advanced design feature which has extremely low inherent transient intermodulation distortion enabling negative feedback (necessary in traditional amplifier design but undesirable) to be reduced to the absolute minimum.
    Power amplifier design too, shows a departure from tradition resulting in the elimination of DC drift.
    Differential push/pull amplifier stage eliminates open-loop distortion. The driver stage is 3-stage darlington connected.
    Specifications:
    —Power output: 85 watts per channel into 8Ω (stereo)
    —Frequency response: 20Hz to 20kHz
    —Total harmonic distortion: 0.025%
    —Damping factor: 60
    —Input sensitivity: 2.5mV (MM), 150mV (line)
    —Signal to noise ratio: 78dB (MM), 100dB (line)
    —Channel separation: 60dB (MM), 65dB (line)
    —Output: 150mV (line), 1V (Pre out)
    —Speaker load impedance: 8Ω (minimum)
    —Dimensions: 430 x 168 x 389mm
    —Weight: 17.8kg
    —Year: 1978
    Sansui TU-717 — SPECS:
    Description:
