This 1973 Harman Kardon 50+ receiver is kind of a rare bird. It’s a really warm sounding low watt receiver in good working/cosmetic condition that I used to drive some 1985 Klipsch Heresy speakers or some early 70s Sony speakers and it never failed me. I have lubricated all of the pots and switches and added new bulbs across the front so it laminates nicely. I have soaked the knobs and they are nice and clean. I am including an original owners manual that I tracked down for this unit that is in excellent condition. This is a nice piece for any vintage audio setup.
