You are bidding on a vintage HF-81 Eico tube intergrated amplifier. Item is being sold as is as found with no returns. I cannot guarantee anything on this unit because of its age. I did plug it in and it did power on. The red light came on. I hooked up one speaker and used a Bluetooth device hooked up to my iPhone. The one speaker did play. I’m sure it needs some kind of tune up I opened it up and took some pictures of the inside. I don’t know much about this unit . So I will try and answer your questions as best as possible. NO RETURNS . Item weighs about 25 pounds.
