    Power supply for little halogen light popped

    Sir bushtech . . . . . You say . . . Could it really be drawing 14.5μA Its possible . . . .in considering that the power oscillator configuration is not starting up with the voltage drop and the current starving , impeded by the presence of the incandescant lamp being placed inline with the...
