When we aquired the van the left speaker did not work.
It's an 80's tape deck with 80's speakers so no biggy.
The speaker that worked sounded terrible anyway, so two new speakers here we come.
Left speaker still didn't work.
Swap speakers over and again left speaker still didn't work.
Fiddle with the wiring and the knobs, nup nothin.
Oh no, time to bin the tape deck.
Start pulling things apart and hang on, what's this.
FADER.
Rotate knob from "all right" to "central", and wham, stereo sound.
