Homebrew 6L6 Rig
  

I built the 6V6 oscillator rig with my son N2PNA when he first got his HF license. We finished it in 2 days on a Thanksgiving break from school. The first day, he worked VE3 Canada all the way down the east coast to Florida. Lots of fun!

This rig belongs to another ham. I helped him get it stabilized. It was oscillating. He now uses it with a nice Hallicrafters VFO. It uses a 6AG7 and a 6L6 for about 18 watts out on 80 meters. Plate voltage is 410 V to take advantage of the bigger tube.

Do not exceed 300 V on the 6AG7 plate. See 6AG7 specs and information:

Efficiency is better with the buffer stage. Chirp free on xtal or VFO. He is planning to add 40 meters with a plug in output coil. It has pi network output for easy matching instead of link coupling.

I plan to build one for myself when I have a chance.

Check out these pages for more information. This correct 6L6 information is not found anywhere else on the web. Further, there is a lot of inaccurate information out there which is explained. Before you build, read the specs!
