    I stated to use proteus for circuit drawing and simulation to learn different concepts. I tried a simple joule thief circuit using a 1.5DC to drive an LED which you can see just about anywhere on the net.

    I stated with just an LED to source which glowed. I added a transistor with base on the power source which also worked. When I tried to add the transformer and hoping the 1.5V input would light the bulb it gives no lighting or amplification. Is there something the program is needing regarding the transformer?
