I take great pride in preserving all of the audio components I sell and believe them to be in fantastic shape to last for years to come. But the nature of all such vintage electronics is unpredictable and issues could always arise at any time (it is vintage after all, not brand new). As a result, this item is sold as-is without any explicit guarantees given about long-term function past when it is received and with no returns. Ive been selling quality used Audio and Stereo components (receivers, amplifiers, turntables, cd players, equalizers, speakers, etc.) from the 70s - mid 90s in the Sarasota area of Florida for several years. Most are in excellent condition, cleaned and tested with no known issues! I also sell items that are marked as non-working or possibly repairable as well as individual used parts. Thanks for looking and please check out my other offers. New items from ONKYO, JBL, Technics, Kenwood, Yamaha, Infinity, Sony, Denon, Pioneer, Bose, NAD, Nakamichi, Marantz, Teac, Audio-Technica, and Realistic listed every week!
