07/26/24 update on shipping,please send me your zip code and i will get you a quote,i removed the fixed shipping since that was a long time ago and shipping is more expensive now,ill post very soon pictures of the inside.Harman Kardon Vintage Citation Sixteen S Power Amp,will do my best to explain this unit,first theres no warranty is very very old unit from 1977,i paint the top metal and the bottom outside since it was fading the front plate has scratches nicks and marks that i retouched with black special marker and looks way better,i try not to erase the model and names so everything can be seen,the corners of the front plate are bent and the left side is separated from the chassis,all this does not affect the sound of the unit,both channels works and i just wait at least 5 minutes to raise the volume,after 20 minutes on the magic starts,wao the word i can say,super detail,huge background and very tight bass,this thing has power,the huge 4 caps from top looks fine but remember these are from 1977 dont know if the amp will need a refresh or something,but both channels works,ill be more than happy to answer questions and if want that i open the top and send pics of the inside i will do it,again no guarantee on this unit,no returns is huge and heavy and will be double box.
