RE: Circlotron with MOSFET output

You wrote: "Mr Paul Hynes SS Fet Circlotron circuit is basically correct , but need bias circuit for output Fets which is not present on schematic from your link ! , it could be driven with small SET for sure , but I think that tubes 45 / 2a3 / 300 b is not appropriate for this application since the power MosFet devices usually need only few Miliwat for full gate charge/disharge control."

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!
