6A3sUMMER,
The 20.5 gain stage was measured on unloaded transformer, so it should be (almost) equal to u.
It's possible the model might be off with a .5 gain. Which in real life is completely normal.
The 47k loaded stage will be of course, lower.
I used LTSpice for this with an Ayumi model

50AE,
Why use an unloaded transformer for calculating gain?
What is the impedance at 1 kHz of an unloaded "47k" transformer?
