>Is it SRPP??

No. The lower tube is working against constant current,
therefore single ended... The upper, a cathode follower
also working against constant current, single ended...

There is complete AC disconnect. They push and pull
against totally separate nodes. Not sharing the same
load equally, not a little bit unevenly, simply not at all...

You stack one atop the other as a matter of convenience.
That alone does not make it SRPP any more than makes
Cascode, or Mu-Follower, or Loftin-White, or Anti-Triode,
or anything else for that matter. Though its much closer
to maybe a Mu-Follower than anything else you could
quickly slap an existing label over it...

I still have to think of it as completely separate stages.
Current loaded plate. Current loaded cathode follower...
Isn't quite the classic Mu Follower. Cause the top triode
here is not moonlighting double-duty as current source.
