Can't see it... could you post it somewhere else that is universally
accessible?

You won't be hearing much until you sort out the connections to that
output transformer.


Looks to me like there are two separate identical output transformers,
which has the disadvantage of not cancelling out the partial saturating
effect of the output tube's quescient current, and not maximizing the
cancellation of even order harmonics.


Whoops! I didn't notice that the secondary of one output transformer is
basically connected to the air. That basically negates the existance of the
one half of the output stage!

Hopefully, this is all a consequence of a overly-simplistic modelling
program, as others have pointed out.
