Vintage Panasonic 8 Track Player 4 Channel Model RS-845US Play w/ Issue? READ

Description

No returns.
This is being sold AS-IS for parts/ repair only.
This 8 track player plays & changes track fine.
However I only get a tiny whisper of sound through the right channel.
When I have only the left channel plugged in I get stereo (2 channels of audio) through my amp?
I don't know anything about quadrophonic 4 channels 8 track players & how they're supposed to work.
There is some ware to the finish of the chrome plastic/ some scratches on the wood.
No returns.
This is being sold AS-IS for parts/ repair only.
You'll receive the pictured 8 track player &

else.
