Sansui AU-8500 Integrated Amplifier

I have never been more excited to find a piece of vintage audio gear.

The Sansui AU-8500 Integrated Amplifier was manufactured in the early 70’s. Weighing in at a little over 45 pounds, this machine is a beast.

 

Here are the specifications:

Power output: 60 watts per channel into 8Ω (stereo)

Frequency response: 15Hz to 30kHz

Total harmonic distortion: 0.1%

Damping factor: 50

Input sensitivity: 2.5mV (mic), 2.5mV (MM), 100mV (DIN), 100mV (line)

Signal to noise ratio: 65dB (mic), 75dB (MM), 85dB (line)

Output: 100mV (line), 30mV (DIN), 0.8V (Pre out)

Speaker load impedance: 4Ω to 16Ω

Semiconductors: 58 x transistors, 2 x FET, 33 x diodes, 5 x zener diodes

Dimensions: 140 x 500 x 347mm

Weight: 20.5kg

This amp looks as good as it sounds. The black front plate and sexy stainless trim, these are commonly referred to as “The Black Face” amps.

This amp has two headphone inputs. The first will shut the speakers off when being used, but if the second one is used alone, the speakers will stay on. Nice feature.

Also there are two phono inputs in the back allowing me to have two turntables set up and ready to go. I love this feature as I like using my fully manual table for everyday listening but like to use my automatic turntable while relaxing in the evenings (so if I fall asleep listening, the player will shut off).

This is my new pride and joy of my collection and will definitely be my “main” amplifier for the foreseeable future.

My three year old daughter loved my new toy and insisted she take a picture of it. This last shot was taken by her!
