Re: Is this transitron really?

As a follow-up, I found few more circuits of the same type browsing old
books and googling for "tube oscilloscope" and now I believe the author
of the original description was really confused for supposedly this
schematic is some variant of what is called "Phantastron". Still I hope
to learn a bit more about it and perhaps research a bit more,
practically.
