What we have here is a Kenwood stereo synthesizer tuner KT-57 I’m not technician person but what I have here I try and show the buyers what I have by taking photos of the condition of the item as you can see in my photos it does turn on. I’m unsure if it works cause I don’t have speakers to put in it, to test it, but overall it’s in good condition for its age. Please look at photos.
