The aluminum chassis was made for me by Walt Martin, KB5HOV, out of 1/16" aluminum. The enclosure is a 1950s Bud hinged-top steel cabinet with black wrinkle finish. The PA plate and loading capacitors were made by E.F. The PA grid tuning capacitor is a vintage Hammarlund. The plate current meter is war-surplus item made for the U.S. The steatite crystal socket and 807 plate cap are James Millen parts. The tube sockets and coil sockets are steatite with silver-plated contacts, probably made by E.F. The oscillator and PA tank coils are wound on 1-1/4" diameter red bakelite 5-prong coil forms from an unknown manufacturer. I used as many vintage parts as possible during construction to ensure that the finished product would have a 1950s look. ![]() In early 2004, I modified the circuit so as to allow VFO operation. It started out with a 6V6 in the oscillator, but I rebuilt the oscillator section in the autumn of 2003 and changed the tube to a 6AG7. The note and keying are about as clean as you're likely to hear from a homebrew rig. The oscillator design is directly out of any 1960s ARRL Handbook, and the basic design for the final came from one of my favorite project books, "104 Ham Radio Projects for Novice and Technician" (TAB Books, 1968). I've built many transmitters over the years, but this one was definitely the most fun! It uses a 6AG7 crystal oscillator to drive an 807 final.
