[Jukebox-list] Seeburg reversing switch contact problem

[Wesley Dean]

    Chad, any open leaf switch set should have follow through by the primary 
blade exerting pressure on the secondary blade. Earlier reversing switches 
had a .1 mfd.at 600 capacitor across the motor winding that is switched by 
the reversing switch.  Wes
