Acoustic research ARAU amplifier. This unit is apparently completely original and appears to have never been serviced. As the photographs will show, this unit has been lovingly taken care of with almost no physical imperfections noted whatsoever. I ran it for over three hours, and the heat sinks never got warm to the touch. All that being said, this unit is over 50 years old and should be recapped appropriately. With the appropriate electrolytic capacitors replaced, this should last a very long time. If you are looking at this listing, you know what this amplifier is. Due to the age of this unit and the unrestored fully original nature of it, it is being sold as is as described. I make no warranty whatsoever as to the longevity of its operation in the condition that it sits, although it sounds very good to me at this point. Please consider that this is a candidate for a full restoration, and not something to be used long-term in its all original condition.

Tested for power. Seems to work based off of the source. Not tested further

Gorgeous AR amp with wooden case. Powers on, have not been able to verify output, I dont have any thing to plug into inputs. May or may not work how its supposed to, sat for many years in the closet. Audiophile
