Radio Receiver Projects You Can Build Buy the Book Today! The volume potentiometer controls the grid bias voltage on the 6V6 tube, when the volume is all the way down, the grid is grounded.Construction Techniques, Component ID, Soldering, etc.īuild Your Own Intelligent Amateur Radio Transceiver by Randy Lee Henderson Buy the Book Today! The voltage then comes out of the tube through a interstage capacitor into the 6V6 tube that drives the audio transformer. ![]() This tube amplifier uses the dual triode 12AX7 tube to first amplify the small signal voltage that comes from audio in. As long as the circuit diagram is closely followed, this tube amp should work. ![]() Make sure all the solder joints are secure and make sure that all the necessary components have been used. When wiring, pay special attention to the voltage and wattage ratings of the capacitors and resistors. Wire all the ground connections to the the copper clad plate on the bottom and isolate any connections and solder joints from the ground using nails hammered into small wood cubes. Follow the lines in the diagram and connect the different shown components together by way of the the lines in the diagram. To wire the audio circuit, you mostly have to just follow the circuit diagram. ![]()
