Hi fellas hope ya can help, I just got this Pioneer CK-3 boombox it sounds great on both sides of the amp right and left when using the tuner but when I play a cassette it plays only on the right side only no sound comes out of the left side, I sprayed contact cleaner everywhere I even recorded rewind and then press play and still no luck. I wish it would be a simple fix. Any suggestions as always I'll really appreciate them all .
