  1. First of all, where're connection of your load or smoothing inductor? Sound like u r reversing both output transistor. both of them are NPN transistor, they need higher voltage at Collector and lower voltage at Emitter to switching. any mean, U must have some pull up transistor at Collector (pin 12&13) to forward bias them. regard.
