I found this Pioneer KX 555 stereo reciever in a not to good cosmetic condition, no idea if it works or not and the owner of the store wanted to power it up directly from mains. i stopped him and said he might just blow something. any way as you can see cosmetically it needs some work. ive searched the google and found it to be rare (based on e-bay and likes) i would like to offer something on this and clean it up but i have no idea where to start with an offer. keep in mind we have no idea if it works. any suggestions on a reasonable offer?
