Hi, Tamura Kentai:
The example is NOT suitable to used in the real world, it's just a demo to see if the STR-A6100 could behave well.
It's absolutely not suggested to use it in real world.
Especially, the transformer was just roughly put parameters, it's meaningless and absolutely NOT proper-tunned.
And the model of STR-A6100 is just simple sub-circuit for behavior reference.
I really hope to see the day, those companies could release those models of SPICE to their customers to spread their application of those products.
For example, if I never use the STR-A6100 IC, I would never know there is a company called (sanken) exists in the world.
Thank you for your opinions.
Best regards.?
