PIONEER QX646 Stereo Receiver Description

Pioneer QX646 Fm Quadraphonic Stereo Receiver QX-646
Qx646 Pioneer Vintage Quadraphonic Stereo

It will be double boxed and shipped securely. A good clean signal and sound comes through the aux input with CD player using small set of PBS bookshelf speakers. I do not have the int ructions on how to patch or use quad system correctly. All controls that could be tested work fine.

I didn't see any burned out lamps but the 2ch is a little faint when lit. It is a little dusty and could stand detail cleaning. One of the balance controls has a faint scratching when turned that may go away with use or shot exit. The unit powers on just fine and has been tested a two channel set up.

The receiver comes fro a clean smoke free home. The signal is really faint and garbled. This is a one owner and has not been abused in any way. The cabinet is solid and only has small imperfections.

Thanks for looking. I did try to operate the quad system but it doesn't come through correctly using a 2 channel set up.
