RE: Circlotron with MOSFET output

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.
Still I think that hybrid design from Mr.Andrea Ciufolly (Audiodesign) is the right one !, to rise the desired output power is enough to add few more 2SK1058 devices in parallel .
