VERY BIG UNIT & HEAVY

Vintage Pioneer 4 Channel Reciever Model QX-9900 When transporting the unit, the power cord got stuck on something and ended up ripping off at the entry point of the receiver. The top wood paneling isnt in greatest shape. The front of the unit appears to be pretty good though all the knobs are present no major scratches or dings or anything. Because of the cord issue, it is untested condition was unknown before I bought it. I just dont have the time to do anything with it right now have a lot of family things going on, and such selling it as is a low price. It is sold as is working condition unknown no warranty no return.
