No ideas has been received about the original clone so this thread can be closed.

The developments on my new Circlotron project will be described in the relative web page on my web site.

I have a quick and dirty concept how the tube-part perhaps can be built

after tube2 is a Resistor as Levelshifter.

Trivial problem, feedback has to go from the other side of the circlotron. However, the phase then relies on the input transformer to do correct phase splitting. Otherwise, your input stage (1st) must be set up as a differential amplifier so it does the phase splitting itself. Feedback can still be connected to the 1st stage cathodes, but I'll leave it to you to figure it out, it's not too difficult
