The bias circuit is not an issue since my friend can take care of it. However, for few milliwatt, I guess a step up transformer is more appropriate than any tubes, right? However, we still need gain from the driver, is it?
Anyonbe can think of any small DHT tube that will work in Paul Hyness circlotron output circuit assume we have a step down phase splitting interstage transformer between the circlotron output section and the DHT driver?
Thanks for the info!
