Just got this Pioneer from member Larry (upbnsffrfan). He received it after buying it but didn't have room so he sent it straight to me in original packed box that he never even opened. Well I received it today and it was packed so so but that wasn't the real issue. When I went to test it I got nothing at all. So I opened it up and to my amazement the power wires and antenna wires were unhooked. Then I noticed something else. Tons of wires that were from deck were all cut. I mean every single wire including the head and erase head wires. Some dumb A$$ cut all of them. I was in awe but the restoring must go on 
It's too much to type so lets just put it this way. I was able to reattach all wires by soldering them back to board. Luckily the moron who cut them did it close enough and because wires were long enough it wasn't to hard. The only other issue was the wires from heads. I ended up using a set of heads that came out of parts GF777 deck with all wires still intact. The heads were the same only difference was the grounding of head but I used ground wire off the 777 deck and everything is fully attached, maybe close to 15 wires total were cut. I have pics of most of them
I also cleaned everything because it was pretty dirty. I also put new belts on and cleaned and demagnetized head. I painted grills and used black permanent marker on speakers. Cleaned up all chrome and straightened out pause button. To my amazement after I was all done getting it back together and replacing broken antenna the box worked excellent. I adjusted azimuth on tape head and it sounded beautiful. I just couldn't how stupid some people are. Well here are the pics. Enjoy
