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 much higher
to take advantage of the bigger tube. 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
I plan to build one for myself when I have a chance.
