Nikko NA-550 Integrated Amplifier in good condition. Sounds excellent, warm sound common to Japanese stereos of this era. Fifty (conservative) watts if power into 8 ohms. I used it to power a pair of Vandersteen 2s (inefficient and sometimes difficult to drive) with no issues. Cleaned every pot, slider, and mechanical electrical interface with deoxit, no popping or hissing when operating any of the functions. A few nicks here and there as to be expected on a 45 year old piece of equipment but overall good condition.
