hello
i have assembled a video transmitter circuit. its not working. the base voltage of Q4 is zero. please see if the circuit is correct. i don't see how the base receives it's voltage, because there is no connection from the positive supply to the base. or does it turn on by the ac signal voltage? also verify the layout.i am a beginner to CAD. i have used long trace to connect L2 to base of Q1. does it have any effect on the inductor.please help.
