I always recommend taking vintage stereo gear to a professional tech to look it over and ensure that it works 100%. Because it is a vintage unit I cannot guarantee that the unit is fully functional. I describe it to the best of my abilities, but I am not a tech --I am just a hobbiest. Because of the age of this unit it is being sold AS IS. Please send any questions you may have before bidding/making an offer. THANKS!
