While searching on the Internet, I came across an article from "The Heart of Texas DX Society" about building a simple one tube transmitter using a common 6L6 Power Beam Tetrode Tube. This got my creative juices flowing and I decided this will …

The kit includes terminal strips, solder lugs, tube sockets, wire, newly manufactured variable capacitor, resistors and tested NOS or imported 6V6 or 6L6 vacuum tube, and a very detailed step by step manual.

I originally built this rig in 1998. 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. In early 2004, I modified the circuit so as to allow VFO operation.

cw transmitter schematics. a classic cw transmitter design, using only the 6ag7 tube.... the 6l6, 6f6, or the 6v6 tube can be used in this circuit for another excellent cw transmitter....

Many of us started with these - a single 6V6 and a single 3S4. A Novice T.R. Switch by Lew McCoy, W1ICP. While this switch passes too much power for modern solid state rigs, this 6AH6 pentode switch is perfect for vintage tube stations.

In general, the 6V6 output power measured into a 50 ohm load runs about 9W on most bands (depending on whether the final is doubling or running straight-through) down to 8 watts on 10m. Output on both 160 and 80m is 5 watts.

This simple transmitter used a 6V6 (or 6L6) vacuum tube on a chassis made of orange crate wood. It was designed for the amateur radio operator to send CW (code) on 80 or 40 meters. Our more recent kit uses a metal chassis and an improved oscillator kit introduced in …

My transmitter runs at 60 ma. A 6V6 tube is typically 30-35 ma. I use FT-243 crystals and have had no problems. The variable capacitors came from junked broadcast sets and work well for lower voltage transmitters. Most are around 365 pf. which will allow tuning into most antennas.

The 6L6 transmitter is now installed at LA9LE. The 6L6 transmitter is connected to my automatic RX / TX switch.

Apr 4, 2017 · We started the Pine Board Project with a 6X5 vacuum tube rectifier to change the secondary AC voltage of the transformer to D.C. That tube is a half-wave rectifier. See below for a great video explanation from George Thomas about how and why this works.
