Vacuum Tube Audio Preamplifier

With a small group of Electronics enthousiasts near Paris, we decided to build a simple Vacuum Tube Preamp (for Headphones), powered under 12V. (There are multiple schematic examples on the Web) . So we have done our own CAD Schematic and PCB Layout using EaglePCB Cad. The next step was to make the PCB, so we considered to use PCBWay, recommanded by a member of the group. Impatient to receive the PCBs, we selected a fast delivery option. The quality was very good, and we started the wiring immediately after receiving the parcel (could not wait..) . Except one missing wire (forgotten during CAD layout...) the Audio Preamp worked to perfection! The vacuum tube (ECC82/12AU7) really gives a magic sound (See picture)
